しかしながら、特許文献1に開示されている位置合わせ装置では回動手段の内部に温調手段を設けているため、回動手段が重くなることで回転駆動に負荷がかかってしまう。
また、回動手段の回転を考慮して温調手段に温調用チューブや制御ケーブル等の配線を接続する必要があるため、構造が複雑化してしまう。
そこで本発明は、駆動における負荷を低減すると共に、簡易な構造で基板の温調を行うことができる位置合わせ装置を提供することを目的とする。
However, in the positioning device disclosed in Patent Document 1, since the temperature control means is provided inside the rotating means, the rotating means becomes heavy and a load is applied to the rotation drive.
Further, since it is necessary to connect wiring such as a temperature control tube and a control cable to the temperature control means in consideration of the rotation of the rotating means, the structure becomes complicated.
Therefore, an object of the present invention is to provide an alignment device capable of reducing the load in driving and controlling the temperature of the substrate with a simple structure.

本発明に係る位置合わせ装置は、第一面に基板を保持する基板保持部と、基板保持部を介して基板を温調する基板温調部と、基板保持部を移動させる駆動部と、駆動部を制御する制御部とを備え、基板温調部は、第一面とは異なる、基板保持部の第二面と接触した状態で基板を温調することを特徴とする。 The alignment device according to the present invention includes a substrate holding portion that holds the substrate on the first surface, a substrate temperature controlling portion that controls the temperature of the substrate via the substrate holding portion, a driving unit that moves the substrate holding portion, and a drive unit. A control unit for controlling the unit is provided, and the substrate temperature control unit is characterized in that the temperature of the substrate is controlled in a state of being in contact with the second surface of the substrate holding unit, which is different from the first surface.

本発明によれば、駆動における負荷を低減すると共に、簡易な構造で基板の温調を行うことができる位置合わせ装置を提供することができる。 According to the present invention, it is possible to provide an alignment device capable of reducing the load in driving and controlling the temperature of the substrate with a simple structure.

以下に、本実施形態に係る位置合わせ装置を添付の図面に基づいて詳細に説明する。なお、以下に示す図面は、本実施形態を容易に理解できるようにするために、実際とは異なる縮尺で描かれている。
なお、以下の説明では、基板保持部3の基板保持面(第一面)に垂直な方向をZ軸としており、Z軸に垂直な平面内において互いに直交する二方向をそれぞれX軸及びY軸としている。
The alignment device according to the present embodiment will be described in detail below with reference to the accompanying drawings. The drawings shown below are drawn at a scale different from the actual ones so that the present embodiment can be easily understood.
In the following description, the direction perpendicular to the substrate holding surface (first surface) of the substrate holding portion 3 is defined as the Z axis, and the two directions orthogonal to each other in the plane perpendicular to the Z axis are the X axis and the Y axis, respectively.

近年、半導体デバイスにおけるパターンの更なる微細化を達成するために、所定の製造プロセスにおいて基板の温調が行われている。
特に露光装置では、基板位置合わせ工程の前に基板温調工程を行うことで基板の温度分布を均一にすることによって、重ね合わせ精度を向上させることができる。
In recent years, in order to achieve further miniaturization of patterns in semiconductor devices, the temperature of the substrate has been adjusted in a predetermined manufacturing process.
In particular, in an exposure apparatus, the overlay accuracy can be improved by performing a substrate temperature control step before the substrate alignment step to make the temperature distribution of the substrate uniform.

しかしながら、基板位置合わせ工程の前に基板温調工程を設けると、基板温調工程を行うための装置へ基板を搬入した後、基板位置合わせ工程を行うための装置へ搬送するための時間が必要となるため、基板の処理速度が低下し生産性が下がってしまう。
そこで、生産性の低下を抑制するために、基板位置合わせ装置に基板の温調機能を持たせる技術が提案されている。
However, if the substrate temperature control process is provided before the substrate alignment process, it takes time to carry the substrate to the device for performing the substrate temperature control process and then to transport the substrate to the device for performing the substrate alignment process. Therefore, the processing speed of the substrate is lowered and the productivity is lowered.
Therefore, in order to suppress the decrease in productivity, a technique has been proposed in which the substrate alignment device has a substrate temperature control function.

また、例えば基板を回転させるための回動手段内に温調手段を設けると、回動手段が重くなるため、基板の回転速度が低下すると共に、回転させるための駆動装置に大きな負荷がかかることとなる。
また、回動手段の回転を考慮して温調用チューブや制御ケーブル等の配線を温調手段に接続させる必要が生じ、構造が複雑化してしまう。
そこで本実施形態に係る位置合わせ装置は、そのような課題を解決することを主な目的としている。
Further, for example, if the temperature control means is provided in the rotating means for rotating the substrate, the rotating means becomes heavy, so that the rotation speed of the substrate is lowered and a large load is applied to the driving device for rotating the substrate. It becomes.
Further, it becomes necessary to connect the wiring of the temperature control tube, the control cable, etc. to the temperature control means in consideration of the rotation of the rotation means, which complicates the structure.
Therefore, the alignment device according to the present embodiment has a main purpose of solving such a problem.

これにより、基板温調部8に設けられた不図示の温度計測部を監視しながら、基板保持部3との熱接触を介して基板1を所定の温度に温調制御することができる。つまり、基板温調部8は、基板保持部3の基板保持面とは反対の底面と接触した状態で、基板1を所定の温度に温度制御することができる。また、基板温調部8が接触する面は、基板保持面と反対の底面だけに限らない。例えば、基板保持部3の側面であってもよく、基板保持部3の基板保持面とは異なる面(第二面)であればよい。
また、基板1の温度を調節する方法は流体を基板温調部8へ流入させる方法に限られず、基板温調部8にペルチェ素子等の熱電素子を設けて電気的な操作を行うことで基板1の温度を調節してもよい。
The substrate temperature control unit 8 has a mechanism capable of adjusting the substrate 1 to a predetermined temperature, and in the alignment device 60 according to the present embodiment, a fluid such as water or antifreeze at a predetermined temperature is applied to the substrate temperature. It is flowing into the tuning part 8.
As a result, the temperature of the substrate 1 can be controlled to a predetermined temperature through thermal contact with the substrate holding unit 3 while monitoring the temperature measuring unit (not shown) provided in the substrate temperature adjusting unit 8. That is, the substrate temperature control portion 8 can control the temperature of the substrate 1 to a predetermined temperature in a state of being in contact with the bottom surface of the substrate holding portion 3 opposite to the substrate holding surface. Further, the surface that the substrate temperature control portion 8 contacts is not limited to the bottom surface opposite to the substrate holding surface. For example, it may be the side surface of the substrate holding portion 3, and may be a surface (second surface) different from the substrate holding surface of the substrate holding portion 3.
Further, the method of adjusting the temperature of the substrate 1 is not limited to the method of allowing the fluid to flow into the substrate temperature control portion 8, and the substrate is electrically operated by providing a thermoelectric element such as a Perche element in the substrate temperature control portion 8. The temperature of 1 may be adjusted.

また、基板温調部8は、基板保持部3に対して十分大きな面積で接触するように配置することが好ましい。
さらに、基板温調部8は、温調を行う基板1より大きい面積で基板保持部3に接触することがより好ましい。
このため、本実施形態に係る位置合わせ装置60では、基板1が載置されている基板保持部3の底面に接触するように基板温調部8を配置させており、その接触面積は基板保持部3の底面積と略同一であると共に、基板1の面積より大きくなっている。
Further, it is preferable that the substrate temperature control portion 8 is arranged so as to come into contact with the substrate holding portion 3 in a sufficiently large area.
Further, it is more preferable that the substrate temperature control portion 8 comes into contact with the substrate holding portion 3 in an area larger than that of the substrate 1 for temperature control.
Therefore, in the alignment device 60 according to the present embodiment, the substrate temperature control portion 8 is arranged so as to come into contact with the bottom surface of the substrate holding portion 3 on which the substrate 1 is placed, and the contact area thereof holds the substrate. It is substantially the same as the bottom area of the portion 3 and is larger than the area of the substrate 1.

これにより、底面全体が基板保持部3に接触している基板1を基板温調部8によって均一に温調することができ、基板1の温調におけるムラを抑制することができる。 As a result, the substrate 1 whose entire bottom surface is in contact with the substrate holding portion 3 can be uniformly temperature-controlled by the substrate temperature control portion 8, and unevenness in the temperature control of the substrate 1 can be suppressed.

また、基板保持部3と基板温調部8との間の接触は、基板1に対する温調性能に大きな影響を与える。
そのため、基板保持部3と基板温調部8とを互いに物理的に締結する、両者の界面の摩擦係数をなるべく小さくする、両者を互いに真空吸着させる等を行うことによって、有効接触面積をなるべく大きくすることが好ましい。
また、基板温調部8の基板保持部3に対する接触部、すなわち基板温調部8の上面の材質は、例えば、銅に代表される金属や熱伝導性の高いセラミックス(例えば、SiC)等、熱伝導率が高いものであることが好ましい。
Further, the contact between the substrate holding portion 3 and the substrate temperature controlling portion 8 has a great influence on the temperature controlling performance with respect to the substrate 1.
Therefore, the effective contact area is made as large as possible by physically fastening the substrate holding portion 3 and the substrate temperature controlling portion 8 to each other, reducing the friction coefficient at the interface between the two as much as possible, and vacuum-adsorbing the two to each other. It is preferable to do so.
Further, the material of the contact portion of the substrate temperature control portion 8 with respect to the substrate holding portion 3, that is, the upper surface of the substrate temperature control portion 8 is, for example, a metal typified by copper, ceramics having high thermal conductivity (for example, SiC), or the like. It is preferable that the thermal conductivity is high.

次に、本実施形態に係る位置合わせ装置60による動作について説明する。 Next, the operation by the alignment device 60 according to the present embodiment will be described.

まず、図1(a)に示されているように、位置合わせ装置60に基板1が搬入されると、基板保持部3上に基板1が載置される。
そして基板1が基板保持部3上に載置されると、まずZ軸駆動部7を駆動させることによってθ軸駆動部6が上昇する。
それにより、図1(b)に示されているように基板保持部3及び載置されている基板1が上昇し、基板保持部3が基板温調部8に対して離間する。
First, as shown in FIG. 1A, when the substrate 1 is carried into the alignment device 60, the substrate 1 is placed on the substrate holding portion 3.
When the substrate 1 is placed on the substrate holding portion 3, the θ-axis drive portion 6 is raised by first driving the Z-axis drive portion 7.
As a result, as shown in FIG. 1B, the substrate holding portion 3 and the mounted substrate 1 are raised, and the substrate holding portion 3 is separated from the substrate temperature controlling portion 8.

そして、基板1に形成されているノッチ1aが所定の検出部2の検知範囲内の所定の位置に位置づけられるように、θ軸駆動部6を駆動することによって基板保持部3及び載置されている基板1をZ軸周りの回転方向、すなわちθ軸方向に回転させる。その後、残りの2つの検出部2が基板1のエッジ(縁部)を検出する。
このようにして、三つの検出部2によって検出された基板1の各位置に基づいて、位置合わせ装置60上に配置された際の基板1のX軸、Y軸及びθ軸における位置が決定される。
Then, the substrate holding portion 3 and the notch 1a formed on the substrate 1 are placed on the substrate holding portion 3 by driving the θ-axis driving portion 6 so that the notch 1a is positioned at a predetermined position within the detection range of the predetermined detection unit 2. The substrate 1 is rotated in the rotation direction around the Z axis, that is, in the θ axis direction. After that, the remaining two detection units 2 detect the edges of the substrate 1.
In this way, the positions of the substrate 1 on the X-axis, Y-axis, and θ-axis when placed on the alignment device 60 are determined based on the positions of the substrate 1 detected by the three detection units 2. NS.

次に、上記のように決定された位置に基づいて、以下のように基板1の位置合わせを行う。
まず、基板1のθ軸における位置合わせを行うために、上記のように決定された基板1のθ軸における位置に基づいて、基板1がθ軸における所定の位置に移動するように、θ軸駆動部6を駆動させる。
これにより、基板保持部3及び載置されている基板1をθ軸方向に回転させる。
Next, the substrate 1 is aligned as follows based on the positions determined as described above.
First, in order to align the substrate 1 on the θ axis, the θ axis is moved so that the substrate 1 moves to a predetermined position on the θ axis based on the position of the substrate 1 on the θ axis determined as described above. Drive the drive unit 6.
As a result, the substrate holding portion 3 and the mounted substrate 1 are rotated in the θ-axis direction.

その後、θ軸駆動部6が下降するようにZ軸駆動部7を駆動させることによって、図1(a)に示されているように基板保持部3及び載置されている基板1が下降し、基板保持部3と基板温調部8とが互いに接触する。
そして、基板1のX軸及びY軸における位置合わせを行うために、上記のように決定された基板1のX軸及びY軸における位置に基づいて、基板1がX軸及びY軸それぞれにおける所定の位置に移動するように、X軸駆動部4及びY軸駆動部5を駆動させる。
これにより、Z軸駆動部7及び保持されているθ軸駆動部6がX軸方向及びY軸方向それぞれに移動し、基板温調部8、基板保持部3及び基板1がX軸方向及びY軸方向それぞれに移動する。
After that, by driving the Z-axis drive unit 7 so that the θ-axis drive unit 6 descends, the substrate holding unit 3 and the mounted substrate 1 descend as shown in FIG. 1 (a). , The substrate holding portion 3 and the substrate temperature controlling portion 8 come into contact with each other.
Then, in order to align the substrate 1 on the X-axis and the Y-axis, the substrate 1 is predetermined on the X-axis and the Y-axis, respectively, based on the positions of the substrate 1 on the X-axis and the Y-axis determined as described above. The X-axis drive unit 4 and the Y-axis drive unit 5 are driven so as to move to the position of.
As a result, the Z-axis drive unit 7 and the held θ-axis drive unit 6 move in the X-axis direction and the Y-axis direction, respectively, and the substrate temperature control unit 8, the substrate holding unit 3, and the substrate 1 move in the X-axis direction and the Y-axis direction. Move in each axial direction.

なお、本実施形態に係る位置合わせ装置60では、上記のように基板1のX軸及びY軸における位置合わせの際に基板保持部3を基板温調部8に接触させることで、基板保持部3との熱接触を介して基板温調部8によって基板1を所定の温度に温調することができる。 In the alignment device 60 according to the present embodiment, the substrate holding portion 3 is brought into contact with the substrate temperature controlling portion 8 when the substrate 1 is aligned on the X-axis and the Y-axis as described above. The substrate 1 can be temperature-controlled to a predetermined temperature by the substrate temperature control unit 8 through thermal contact with 3.

また、上記のように基板1のX軸及びY軸における位置合わせを行うと、基板1がθ軸方向に微少量だけ移動する可能性がある。
そこで、基板1の位置合わせにおいて更なる精度が求められる場合には、再度、Z軸駆動部7を駆動させることによって基板保持部3及び載置されている基板1を上昇させた後、基板1のθ軸における位置合わせを行う。
なおこの時、θ軸方向の移動は微少量であるため、Z軸駆動部7を駆動させずに、基板保持部3と基板温調部8とを互いに接触させたまま、基板1のθ軸における位置合わせを行ってもよい。
Further, when the substrate 1 is aligned on the X-axis and the Y-axis as described above, the substrate 1 may move in the θ-axis direction by a very small amount.
Therefore, when further accuracy is required for the alignment of the substrate 1, the Z-axis drive unit 7 is driven again to raise the substrate holding unit 3 and the mounted substrate 1, and then the substrate 1 is placed. Is aligned on the θ axis.
At this time, since the movement in the θ-axis direction is very small, the θ-axis of the substrate 1 is kept in contact with the substrate holding portion 3 and the substrate temperature control portion 8 without driving the Z-axis drive unit 7. You may perform the alignment in.

また、θ軸における位置合わせを行う場合、基板保持部3が基板温調部8から離間することで、基板保持部3と基板温調部8との間の熱接触は弱まってしまう。
しかしながら、互いの間のクリアランスを十分小さくすることで、プロキシミティ効果によって基板1の温調効果の低減を十分抑制することができる。
Further, when the alignment on the θ axis is performed, the substrate holding portion 3 is separated from the substrate temperature controlling portion 8, so that the thermal contact between the substrate holding portion 3 and the substrate temperature controlling portion 8 is weakened.
However, by sufficiently reducing the clearance between each other, it is possible to sufficiently suppress the reduction of the temperature control effect of the substrate 1 due to the proximity effect.

以上のように、本実施形態に係る位置合わせ装置60では、基板保持部3が基板温調部8上に載置されていない状態(第二の状態)になるように、Z軸駆動部7が基板保持部3を基板保持部3の基板保持面に垂直なZ軸方向に移動させる。
次に、基板保持部3が基板温調部8上に載置されていない状態で、θ軸駆動部6が基板保持部3をZ軸方向のまわりに回転させる。
As described above, in the alignment device 60 according to the present embodiment, the Z-axis drive unit 7 is in a state in which the substrate holding unit 3 is not placed on the substrate temperature control unit 8 (second state). Moves the substrate holding portion 3 in the Z-axis direction perpendicular to the substrate holding surface of the substrate holding portion 3.
Next, the θ-axis drive unit 6 rotates the substrate holding unit 3 around the Z-axis direction in a state where the substrate holding unit 3 is not placed on the substrate temperature control unit 8.

その後、基板保持部3が基板温調部8上に載置されている状態(第一の状態)になるように、Z軸駆動部7が基板保持部3をZ軸方向に移動させる。
そして、基板保持部3が基板温調部8上に載置されている状態で、X軸駆動部4及びY軸駆動部5がそれぞれ、基板保持面に基板保持部3の平行なX軸方向及びY軸方向に基板保持部3及び基板温調部8を移動させる。
After that, the Z-axis drive unit 7 moves the substrate holding unit 3 in the Z-axis direction so that the substrate holding unit 3 is placed on the substrate temperature control unit 8 (first state).
Then, in a state where the substrate holding portion 3 is placed on the substrate temperature controlling portion 8, the X-axis driving portion 4 and the Y-axis driving portion 5 are respectively in the X-axis direction parallel to the substrate holding surface of the substrate holding portion 3. And the substrate holding portion 3 and the substrate temperature controlling portion 8 are moved in the Y-axis direction.

なお、不図示の搬送装置によって本実施形態に係る位置合わせ装置60へ基板1を搬送する場合、搬送装置が基板1の上面を保持する場合には、上記の構成で十分である。
しかしながら、搬送装置が基板1の下面を保持する場合には、搬送をサポートするために基板温調部8にピン等を別途設けてもよい。
When the substrate 1 is transported to the alignment device 60 according to the present embodiment by a transport device (not shown), the above configuration is sufficient when the transport device holds the upper surface of the substrate 1.
However, when the transfer device holds the lower surface of the substrate 1, a pin or the like may be separately provided in the substrate temperature control portion 8 to support the transfer.

また、本実施形態に係る位置合わせ装置60に設けられた不図示の制御部によって行われる位置合わせ動作での基板1のX軸、Y軸及びθ軸における現在位置の計測及び所定の位置への移動のための各駆動部の駆動タイミングや順序は、上記の構成に限られない。 Further, measurement of the current position on the X-axis, Y-axis and θ-axis of the substrate 1 in the alignment operation performed by the control unit (not shown) provided in the alignment device 60 according to the present embodiment and to a predetermined position. The drive timing and order of each drive unit for movement is not limited to the above configuration.

以上のように、本実施形態に係る位置合わせ装置60では、基板1と基板温調部8とが互いに直接接触しておらず、基板温調部8が基板保持部3の基板保持面とは異なる面と接触することで、基板保持部3を介して基板温調部8による基板1の温調が行われる。
そして、θ軸駆動部6によって基板1のθ軸における位置合わせを行う際には、基板保持部3と基板温調部8は離間して、基板温調部8は回転せず、基板保持部3及び載置されている基板1が回転する。
As described above, in the alignment device 60 according to the present embodiment, the substrate 1 and the substrate temperature control portion 8 are not in direct contact with each other, and the substrate temperature control portion 8 is a substrate holding surface of the substrate holding portion 3. By coming into contact with different surfaces, the temperature of the substrate 1 is controlled by the substrate temperature control unit 8 via the substrate holding unit 3.
When the θ-axis drive unit 6 aligns the substrate 1 on the θ-axis, the substrate holding unit 3 and the substrate temperature control unit 8 are separated from each other, the substrate temperature control unit 8 does not rotate, and the substrate holding unit 8 does not rotate. 3 and the mounted substrate 1 rotate.

これにより、θ軸駆動部6上の回転体(すなわち、基板保持部3及び載置されている基板1)の重量を低減することができ、回転体の回転速度が増加することで、スループットを向上させることができる。
また、θ軸駆動部6上の回転体の重量が低減することで、各駆動部への負荷を低減させることもできる。
As a result, the weight of the rotating body on the θ-axis drive unit 6 (that is, the substrate holding unit 3 and the mounted substrate 1) can be reduced, and the rotational speed of the rotating body increases, thereby increasing the throughput. Can be improved.
Further, by reducing the weight of the rotating body on the θ-axis drive unit 6, the load on each drive unit can be reduced.

さらに、基板1のθ軸における位置合わせを行う際に基板温調部8を回転させないことにより、基板温調部8に接続される温調用チューブや制御ケーブル等の配線8aを簡単な構造で設けることができる。 Further, by not rotating the substrate temperature control portion 8 when aligning the substrate 1 on the θ axis, wiring 8a such as a temperature control tube and a control cable connected to the substrate temperature control portion 8 is provided with a simple structure. be able to.

また、本実施形態に係る位置合わせ装置70では、基板1のX軸、Y軸及びθ軸の位置合わせにおいて第2の基板保持部3bは基板温調部8に接触したままである。
そのため、第一実施形態に係る位置合わせ装置60に比べて、基板1の温調性能をさらに良好にすることができる。
Further, in the alignment device 70 according to the present embodiment, the second substrate holding portion 3b remains in contact with the substrate temperature control portion 8 in the alignment of the X-axis, the Y-axis, and the θ-axis of the substrate 1.

[Third Embodiment]
FIG. 3A shows a schematic cross-sectional view of the alignment device 80 according to the third embodiment. Further, FIG. 3B shows a schematic cross-sectional view of the alignment device 80 according to the modified example of the third embodiment.
Since the alignment device 80 according to the present embodiment has the same configuration as the alignment device 60 according to the first embodiment except that the configuration of the substrate holding portion 3 is different, the same members are attached with the same components. Numbers are given and explanations are omitted.

図3(a)に示されているように、本実施形態に係る位置合わせ装置80に設けられている基板保持部3は、第1の基板保持部3aと第2の基板保持部3bとから構成されている。
そして、軸部6aの先端部が第1の基板保持部3aの底面に当接するように、θ軸駆動部6の軸部6aが基板温調部8の貫通孔を通って延在している。
As shown in FIG. 3A, the substrate holding portion 3 provided in the alignment device 80 according to the present embodiment is composed of the first substrate holding portion 3a and the second substrate holding portion 3b. It is configured.
Then, the shaft portion 6a of the θ-axis drive portion 6 extends through the through hole of the substrate temperature control portion 8 so that the tip portion of the shaft portion 6a abuts on the bottom surface of the first substrate holding portion 3a. ..

すなわち、本実施形態に係る位置合わせ装置80では、基板保持部3の中心部に位置づけられる第1の基板保持部3aがZ軸方向に移動可能であるように分割されている。
そして、Z軸駆動部7を駆動させることによってθ軸駆動部6が上昇すると、第1の基板保持部3a及び載置されている基板1が上昇し、第1の基板保持部3aが基板温調部8に対して離間する。
That is, in the alignment device 80 according to the present embodiment, the first substrate holding portion 3a located at the center of the substrate holding portion 3 is divided so as to be movable in the Z-axis direction.
Then, when the θ-axis drive unit 6 rises by driving the Z-axis drive unit 7, the first substrate holding unit 3a and the mounted substrate 1 rise, and the first substrate holding unit 3a raises the substrate temperature. Separated from the tuning portion 8.

また、本実施形態に係る位置合わせ装置80では、図3(a)に示されているように、第1の基板保持部3aの厚さ(Z軸方向の大きさ)が、第2の基板保持部3bより大きくなっている。
換言すると、本実施形態に係る位置合わせ装置80では、複数の基板保持部のうち、一部の基板保持部である第1の基板保持部3aの厚みは、残りの基板保持部である第2の基板保持部3bとは異なっている。
Further, in the alignment device 80 according to the present embodiment, as shown in FIG. 3A, the thickness (size in the Z-axis direction) of the first substrate holding portion 3a is the second substrate. It is larger than the holding portion 3b.
In other words, in the alignment device 80 according to the present embodiment, the thickness of the first substrate holding portion 3a, which is a part of the substrate holding portions, is the remaining substrate holding portion. It is different from the substrate holding portion 3b of.

これにより、基板1が図3(a)に示されているような凸形状、すなわち外側にいくにつれて下方に偏位している場合において、第1の基板保持部3a及び第2の基板保持部3bがそれぞれ基板1を良好に保持することができる。
そのため、本実施形態に係る位置合わせ装置80では、凸形状を有する基板1に対して良好に温調を行うことができる。
As a result, when the substrate 1 has a convex shape as shown in FIG. 3A, that is, when the substrate 1 is displaced downward as it goes outward, the first substrate holding portion 3a and the second substrate holding portion 3a Each of 3b can hold the substrate 1 well.
Therefore, in the positioning device 80 according to the present embodiment, the temperature can be satisfactorily adjusted with respect to the substrate 1 having a convex shape.

なお、第1の基板保持部3a及び第2の基板保持部3bの厚さを互いに同一にし、凸形状の基板1を位置合わせする際に第1の基板保持部3aを上昇させるような構成を採ることによって、凸形状及び平坦形状それぞれの基板1の位置合わせを行うこともできる。
この時、凸形状の基板1を位置合わせする際の第1の基板保持部3aの上昇位置は、基板1の保持や温調の程度を考慮して決定すればよい。
The thickness of the first substrate holding portion 3a and the second substrate holding portion 3b are made the same as each other, and the first substrate holding portion 3a is raised when the convex substrate 1 is aligned. By adopting it, it is possible to align the convex and flat substrates 1 respectively.
At this time, the ascending position of the first substrate holding portion 3a when aligning the convex substrate 1 may be determined in consideration of the degree of holding of the substrate 1 and the degree of temperature control.

またそのような構成において、凸形状の基板1を位置合わせするために第1の基板保持部3aを上昇させた際には、第1の基板保持部3aは基板温調部8に対して離間するため、第1の基板保持部3aと基板温調部8との間の熱接触は低減することになる。
しかしながら、第1の基板保持部3aと第2の基板保持部3bとは依然として互いに熱接触している。そのため、第1の基板保持部3aと第2の基板保持部3bとの径方向におけるプロキシミティによって第1の基板保持部3aの温調性能を維持することができる。
Further, in such a configuration, when the first substrate holding portion 3a is raised in order to align the convex substrate 1, the first substrate holding portion 3a is separated from the substrate temperature controlling portion 8. Therefore, the thermal contact between the first substrate holding portion 3a and the substrate temperature controlling portion 8 is reduced.
However, the first substrate holding portion 3a and the second substrate holding portion 3b are still in thermal contact with each other. Therefore, the temperature control performance of the first substrate holding portion 3a can be maintained by the radial proximity of the first substrate holding portion 3a and the second substrate holding portion 3b.

一方、基板1が凹形状、すなわち外側にいくにつれて上方に偏位している場合には、図3(b)に示されているように、第1の基板保持部3aの厚さを第2の基板保持部3bより小さく設計すればよい。
また、図3(b)に示されているような本実施形態の変形例に係る位置合わせ装置80では、所望に応じて第1の基板保持部3aを上下移動させることで、平坦形状、凸形状及び凹形状のいずれの基板1も良好に保持することができる。
On the other hand, when the substrate 1 has a concave shape, that is, the substrate 1 is displaced upward as it goes outward, the thickness of the first substrate holding portion 3a is set to the second thickness as shown in FIG. 3 (b). It may be designed to be smaller than the substrate holding portion 3b of.
Further, in the alignment device 80 according to the modified example of the present embodiment as shown in FIG. 3B, the first substrate holding portion 3a is moved up and down as desired to have a flat shape and a convex shape. Both the shaped and concave substrates 1 can be held well.

なお、本実施形態に係る位置合わせ装置80において基板保持部3を分割する個数や分割された部分の形状は上記に限られない。
また、第1の基板保持部3a及び第2の基板保持部3bの基板1に対する接触面、すなわち上面はそれぞれ平面形状である必要はなく、所望に応じてそれぞれ曲面形状に設計しても構わない。
In the alignment device 80 according to the present embodiment, the number of divided substrate holding portions 3 and the shape of the divided portions are not limited to the above.
Further, the contact surfaces of the first substrate holding portion 3a and the second substrate holding portion 3b with respect to the substrate 1, that is, the upper surface, do not have to have a planar shape, and may be designed to have a curved surface shape as desired. ..

以上のように、本実施形態に係る位置合わせ装置80では、基板1と基板温調部8とが互いに直接接触しておらず、基板温調部8が基板保持部3の基板保持面とは異なる面と接触することで、基板保持部3を介して基板温調部8による基板1の温調が行われる。
そして、θ軸駆動部6によって基板1のθ軸における位置合わせを行う際には、基板温調部8及び第2の基板保持部3bは回転せず、第1の基板保持部3a及び載置されている基板1が回転する。
As described above, in the alignment device 80 according to the present embodiment, the substrate 1 and the substrate temperature control portion 8 are not in direct contact with each other, and the substrate temperature control portion 8 is a substrate holding surface of the substrate holding portion 3. By coming into contact with different surfaces, the temperature of the substrate 1 is controlled by the substrate temperature control unit 8 via the substrate holding unit 3.
When the θ-axis drive unit 6 aligns the substrate 1 on the θ-axis, the substrate temperature control portion 8 and the second substrate holding portion 3b do not rotate, and the first substrate holding portion 3a and the mounting portion 3a are placed. The substrate 1 is rotated.

これにより、θ軸駆動部6上の回転体の重量をさらに低減することができ、回転体の回転速度が増加することで、スループットをさらに向上させることができる。
また、θ軸駆動部6上の回転体の重量がさらに低減することで、各駆動部への負荷をさらに低減させることもできる。
As a result, the weight of the rotating body on the θ-axis drive unit 6 can be further reduced, and the rotational speed of the rotating body is increased, so that the throughput can be further improved.
Further, by further reducing the weight of the rotating body on the θ-axis drive unit 6, the load on each drive unit can be further reduced.

さらに、基板1のθ軸における位置合わせを行う際に基板温調部8を回転させないことにより、基板温調部8に接続される温調用チューブや制御ケーブル等の配線8aを簡単な構造で設けることができる。 Further, by not rotating the substrate temperature control portion 8 when aligning the substrate 1 on the θ axis, wiring 8a such as a temperature control tube and a control cable connected to the substrate temperature control portion 8 is provided with a simple structure. be able to.

また、第2の基板保持部3bに対する第1の基板保持部3aの厚さを調整することで、平坦形状に限らず、凸形状や凹形状の基板1も良好に保持し温調することができる。 Further, by adjusting the thickness of the first substrate holding portion 3a with respect to the second substrate holding portion 3b, not only the flat shape but also the convex or concave substrate 1 can be well held and the temperature can be adjusted. can.

しかしながら、位置合わせ機構の構成を改良することによって位置合わせ時間が短縮し温調時間より短くすることができると、今度は温調時間も短縮しないとスループットを向上させることができない。
そのような場合において、本実施形態に係る位置合わせ装置90のような構成を用いれば基板1の温調制御を最適化することができるため、スループットを向上させることができる。
In the alignment device as in the present embodiment, the time for aligning the substrate 1 is generally longer than the time for adjusting the temperature of the substrate 1.
However, if the alignment time can be shortened and shorter than the temperature control time by improving the configuration of the alignment mechanism, the throughput cannot be improved unless the temperature control time is also shortened.
In such a case, if a configuration such as the alignment device 90 according to the present embodiment is used, the temperature control of the substrate 1 can be optimized, so that the throughput can be improved.

また市場等の要望において、より高精度な温調性能を求められた場合には、温度計測部10の計測結果に基づいて位置合わせ時間を調整することも可能になる。
なお、温度計測部10としては、例えば測温抵抗体やサーミスタ等の温度計を用いることができ、基板1の近傍等、代表的な温度を計測することができる箇所に設けることが好ましい。
Further, when a more accurate temperature control performance is required in response to a demand from the market or the like, it is possible to adjust the alignment time based on the measurement result of the temperature measurement unit 10.
