Thereafter, a paste mainly composed of silver powder, copper powder or tungsten powder is appropriately printed on the front and back surfaces of each green sheet by screen printing, and the paste is filled in the through holes 43 and 45 of each green sheet. The pad electrode 17, the external connection terminal 19, the wiring part 21, the shield member 23, and the connection pad 25 are formed in the same manner.

そして、これら複数のグリーンシートを積層してグリーンシート積層体47を構成し、このグリーンシート積層体47の表面及び裏面に切り込み49a,49bを形成する。この切り込み49a,49bは、個々のセラミック基板3に区画するものであり、格子状に形成されている。さらに、相互に隣り合う各セラミック基板3の間に位置する切り込み49a,49bの一部に、グリーンシート積層体47の厚さ方向に貫通する挿入穴51を形成する。この挿入穴51は、平面視で格子状に形成された切り込み49a,49bのうち、切り込み49a,49bが相互に交差する部分から外れた位置に形成されている。なお、これら切り込み49a,49b及び挿入穴51は、同時に形成されるとしてもよいし、それぞれ別個に形成されるとしても構わない。
最後に、このグリーンシート積層体47を1000℃以上で焼成し、パッド電極17、外部接続端子19及び接続パッド25にニッケル及び金のめっきを施すことで、基板用板材41の製造が完了する。
A plurality of green sheets are laminated to form a green sheet laminate 47, and cuts 49a and 49b are formed on the front and back surfaces of the green sheet laminate 47. The cuts 49a and 49b are divided into individual ceramic substrates 3, and are formed in a lattice shape. Further, an insertion hole 51 penetrating in the thickness direction of the green sheet laminate 47 is formed in a part of the cuts 49a and 49b located between the ceramic substrates 3 adjacent to each other. The insertion hole 51 is formed at a position out of a portion where the cuts 49a and 49b intersect each other among the cuts 49a and 49b formed in a lattice shape in plan view. The cuts 49a and 49b and the insertion hole 51 may be formed at the same time, or may be formed separately.
Finally, the green sheet laminate 47 is fired at 1000 ° C. or more, and the pad electrode 17, the external connection terminal 19, and the connection pad 25 are plated with nickel and gold, thereby completing the manufacture of the board material 41.

また、この製造方法においては、上記基板用板材工程の前後もしくは同時に、蓋体7を多数形成する(蓋体準備工程)。
この蓋体準備工程においては、図6,7に示すように、銅材等の導電性を有する板材にニッケルのめっきを施したものを用意すると共に、この板材に打ち抜き加工を施して、平面視略矩形状の天板部35、及び、天板部35の各辺から一体的に延出する略板状の延出部を形成する。
ここで、天板部35と各延出部との境目には、切欠部57が形成されており、天板部35に対して容易に各延出部を折り曲げることができるようになっている。すなわち、この蓋体準備工程においては、天板部35に対して各延出部を折り曲げる加工を施すことで、天板部35の厚さ方向に突出する側壁部37が形成されることになる。なお、この折り曲げ加工の際には、各側壁部37の先端に、相対する側壁部37から離間する方向に湾曲させる加工も施されている。
Further, in this manufacturing method, a large number of lid bodies 7 are formed before or after the substrate plate material process (cover body preparation process).
In this lid body preparation step, as shown in FIGS. 6 and 7, a nickel plate is prepared on a conductive plate material such as a copper material, and the plate material is punched into a plan view. A substantially rectangular top plate portion 35 and a substantially plate-like extension portion extending integrally from each side of the top plate portion 35 are formed.
Here, a notch portion 57 is formed at the boundary between the top plate portion 35 and each extending portion, and each extending portion can be easily bent with respect to the top plate portion 35. . That is, in this lid body preparation step, a side wall portion 37 protruding in the thickness direction of the top plate portion 35 is formed by performing a process of bending each extending portion on the top plate portion 35. . In this bending process, the end of each side wall part 37 is also subjected to a process of bending in a direction away from the opposite side wall part 37.

また、この蓋体準備工程においては、上記と同様の打ち抜き加工を施して、天板部35に開口部35aを形成する。さらに、この蓋体準備工程においては、コイニング加工により天板部35を変形させて、側壁部37と同じ方向に突出する略環状の突出部39を形成する。
なお、この蓋体準備工程においては、天板部35や延出部、開口部35aを形成する打ち抜き加工や、側壁部37を形成する折り曲げ加工及び突出部39を形成するコイニング加工を、同時に行ってもよいし、個別に行うとしても構わない。
In the lid preparation step, the same punching process as described above is performed to form an opening 35 a in the top plate 35. Furthermore, in this lid body preparation step, the top plate portion 35 is deformed by coining to form a substantially annular projecting portion 39 that projects in the same direction as the side wall portion 37.
In this lid body preparation step, the punching process for forming the top plate part 35, the extension part, and the opening part 35a, the bending process for forming the side wall part 37, and the coining process for forming the protruding part 39 are simultaneously performed. Alternatively, it may be performed individually.

また、前述した基板用板材準備工程の終了後には、絶縁材料からなる接着ペーストB1を介して各凹部11の底面11aに半導体チップ5を多数並べて配置するチップ配置工程を行う。このチップ配置工程においては、各半導体チップ5を配した後に接着ペーストB1を硬化させるペーストキュアを行う。このペーストキュアでは、150℃に加熱した状態をおおよそ1時間保持する。このチップ配置工程の終了後には、ワイヤーボンディングにより半導体チップ5とパッド電極17とをワイヤー31により電気接続する接続工程を行い、ワイヤー31が正しく接続されているかどうかの目視検査を行う。
なお、これらチップ配置工程及び接続工程は、少なくとも後述する重ね合わせ工程の直前に行えばよく、蓋体準備工程の前後もしくは同時に行うとしてよい。
In addition, after the above-described substrate plate material preparation step, a chip placement step is performed in which a large number of semiconductor chips 5 are arranged side by side on the bottom surface 11a of each recess 11 via an adhesive paste B1 made of an insulating material. In this chip arrangement step, paste curing is performed to harden the adhesive paste B1 after the semiconductor chips 5 are arranged. In this paste cure, the state heated to 150 ° C. is maintained for approximately 1 hour. After the end of this chip placement step, a connection step is performed in which the semiconductor chip 5 and the pad electrode 17 are electrically connected by the wire 31 by wire bonding, and a visual inspection is performed to check whether the wire 31 is correctly connected.
The chip placement step and the connection step may be performed at least immediately before a superimposition step described later, and may be performed before or after the lid preparation step.

そして、上述した全ての工程が終了した後に、導電性ペーストB2を接続パッド25上に印刷し、その後、図8に示すように、多数の蓋体7が多数の半導体チップ5を個々に覆うように、多数の蓋体7を基板用板材41の表面3aに重ねて固定する(重ね合わせ工程)。
この際には、各蓋体7の側壁部37をそれぞれ基板用板材41の挿入穴51に挿入する。これにより、多数の半導体チップ5に対する各蓋体7の位置決めを容易に行うことができる。なお、側壁部37の先端は相対する側壁部37から離間するように湾曲しているため、この挿入の際には側壁部37を挿入穴51内に容易に導くことができる。また、この重ね合わせ工程においては、各天板部35の突出部39を上記導電性ペーストB2に接触させる。これにより、蓋体7とシールド部材23とが電気的に接続されることになる。
Then, after all the steps described above are completed, the conductive paste B2 is printed on the connection pad 25, and then, as shown in FIG. 8, a large number of lids 7 individually cover the large number of semiconductor chips 5. In addition, a large number of lids 7 are overlapped and fixed on the surface 3a of the board material 41 (superposition step).
At this time, the side wall portion 37 of each lid body 7 is inserted into the insertion hole 51 of the board material 41. Thereby, each lid 7 can be easily positioned with respect to many semiconductor chips 5. In addition, since the front-end | tip of the side wall part 37 is curving so that it may space apart from the opposite side wall part 37, the side wall part 37 can be easily guide | induced to the insertion hole 51 in the case of this insertion. Moreover, in this superimposition process, the protrusion part 39 of each top-plate part 35 is made to contact the said electrically conductive paste B2. Thereby, the lid 7 and the shield member 23 are electrically connected.

なお、多数の蓋体7を基板用板材41の表面3aに重ねて、突出部39を導電性ペーストB2に接触させた後には、図9に示すように、多数の蓋体7及び基板用板材41を裏返すと共に基板用板材41の裏面3cに金属製の重しMを載せる。そして、この状態で、150℃に加熱した状態をおおよそ1時間保持する導電ペーストキュアを行い、導電性ペーストB2を硬化させる。これにより、多数の蓋体7が基板用板材41に固定され、重ね合わせ工程が完了する。
この重ね合わせ工程が完了することによって、多数の半導体装置1を一体的に連結した半導体ユニット65が構成されることになる。
In addition, after putting many lids 7 on the surface 3a of the board | plate board 41 and contacting the protrusion part 39 with the electrically conductive paste B2, as shown in FIG. 41 is turned over and a metal weight M is placed on the back surface 3c of the board plate 41. In this state, conductive paste curing is performed for about 1 hour in a state heated to 150 ° C. to cure the conductive paste B2. Thereby, many cover bodies 7 are fixed to the board | plate material 41, and a superimposition process is completed.
By completing this superposition process, a semiconductor unit 65 in which a large number of semiconductor devices 1 are integrally connected is formed.

その後、各蓋体7の表面に半導体装置1を識別する名称やシリアル番号等の識別記号N(図1参照)を捺印する。そして、切り込み49a,49bから基板用板材41を破断して、個々の半導体装置1に分割する(分割工程)。
この分割工程においては、図10に示すように、基板用板材41の表面3a側に略円柱状に形成されたローラLの周面L1を下側から押し付けると共に、ローラLを基板用板材41の表面3aに沿う方向に移動させる。これにより、ローラLの周面L1の形状に沿って基板用板材41が折り曲げられるため、切り込み49a,49bの残部が同時に破断され、基板用板材41が個々のセラミック基板3に分割されることになり、固片化された半導体装置1が得られる。
Thereafter, an identification symbol N (see FIG. 1) such as a name or serial number for identifying the semiconductor device 1 is stamped on the surface of each lid body 7. And the board | plate material 41 is cut | disconnected from the notches 49a and 49b, and it divides | segments into each semiconductor device 1 (division process).
In this dividing step, as shown in FIG. 10, the circumferential surface L1 of the roller L formed in a substantially cylindrical shape is pressed from the lower side to the surface 3a side of the substrate plate material 41, and the roller L is pressed against the substrate plate material 41. It is moved in the direction along the surface 3a. Thereby, since the board | plate material 41 is bent along the shape of the surrounding surface L1 of the roller L, the remainder of notches 49a and 49b is fractured | ruptured simultaneously, and the board | plate material 41 is divided | segmented into each ceramic substrate 3. Thus, the solidified semiconductor device 1 is obtained.

なお、この分割工程において、各蓋体7の保護を図るためには、ローラLの周面L1と蓋体7との間に、可撓性を有するシート状の保護部材P1を挟み込むことが好ましい。また、この分割工程においては、分割された半導体装置1が飛び跳ねないように、基板用板材41の裏面に可撓性を有するシート状の抑え部材P2を配することが好ましい。これら保護部材P1及び抑え部材P2は、基板用板材41及び各蓋体7に対して移動しないようになっている。
さらに、この分割工程においては、切断部分を水で冷却するダイシングにより分割する必要がないため、各蓋体7から中空空間S2内に上記水が侵入する不具合が発生することはない。
In this division step, in order to protect each lid 7, it is preferable to sandwich a sheet-like protective member P 1 having flexibility between the peripheral surface L 1 of the roller L and the lid 7. . Further, in this dividing step, it is preferable to arrange a flexible sheet-like restraining member P2 on the back surface of the substrate plate 41 so that the divided semiconductor device 1 does not jump. The protective member P1 and the holding member P2 are prevented from moving with respect to the substrate plate 41 and the lids 7.
Furthermore, in this dividing step, since it is not necessary to divide the cut portion by dicing that is cooled with water, there is no problem that the water enters from each lid 7 into the hollow space S2.

以上の製造方法により製造された半導体装置1においては、図3に示すように、切り込み49a,49bの残部がセラミック基板3の側面3bの一部として構成されることになるため、セラミック基板3の側面3bの一部に破断面3dが形成されることになる。さらに、側壁部37用の挿入穴51は、切り込み49a,49bの残部の破断により半分に分割されるため、セラミック基板3の溝9として構成される、すなわち、挿入穴51の側面が溝9の底面9aとして構成されることになる。   In the semiconductor device 1 manufactured by the above manufacturing method, the remaining portions of the cuts 49a and 49b are formed as a part of the side surface 3b of the ceramic substrate 3 as shown in FIG. The fracture surface 3d is formed in a part of the side surface 3b. Further, the insertion hole 51 for the side wall 37 is divided in half by the breakage of the remaining portions of the cuts 49a and 49b. It will be configured as a bottom surface 9a.

上記のように、この半導体装置1、及び、これに備える蓋体7によれば、重ね合わせ工程において、各蓋体7の側壁部37を基板用板材41に形成された挿入穴51に挿入するだけで、多数の半導体チップ5に対する各蓋体7の位置決めを同時かつ容易に行うことができる。すなわち、各蓋体7により各半導体チップ5を覆う際には、各セラミック基板3が蓋体7の側壁部37に挟み込まれるため、各セラミック基板3に対する天板部35の位置決めを容易に行うことができ、セラミック基板3に対する蓋体7の位置決めを容易に行うことが可能となる。   As described above, according to the semiconductor device 1 and the lid body 7 included in the semiconductor device 1, the side wall portion 37 of each lid body 7 is inserted into the insertion hole 51 formed in the board material 41 in the overlapping process. As a result, the positioning of the lids 7 with respect to a large number of semiconductor chips 5 can be performed simultaneously and easily. That is, when each semiconductor chip 5 is covered with each lid body 7, each ceramic substrate 3 is sandwiched between the side wall portions 37 of the lid body 7, so that the top plate portion 35 can be easily positioned with respect to each ceramic substrate 3. Thus, the lid 7 can be easily positioned with respect to the ceramic substrate 3.

さらに、導電性を有する蓋体7とセラミック基板3のシールド部材23が各半導体チップ5を取り囲んでいる、具体的には、蓋体7の天板部35が半導体チップ5の上方を覆うと共に蓋体7の側壁部37が半導体チップ5の側方の一部を覆っており、また、シールド部材23が半導体チップ5の下方側を覆っている。さらに、これら蓋体7とシールド部材23とは電気的に接続されており、蓋体7及びシールド部材23の電位が同一となる。
以上のことから、これら導電性を有する蓋体7及びシールド部材23により、半導体装置1の外方側に発生した電気的なノイズが中空空間S2に侵入することを防いで、半導体チップ5に到達することを防止できる、すなわち、ノイズに基づく半導体チップ5の誤作動を確実に防止することができる。
Further, the conductive lid 7 and the shield member 23 of the ceramic substrate 3 surround each semiconductor chip 5. Specifically, the top plate portion 35 of the lid 7 covers the upper side of the semiconductor chip 5 and the lid. The side wall portion 37 of the body 7 covers a part of the side of the semiconductor chip 5, and the shield member 23 covers the lower side of the semiconductor chip 5. Further, the lid body 7 and the shield member 23 are electrically connected, and the potentials of the lid body 7 and the shield member 23 are the same.
From the above, the conductive lid 7 and the shield member 23 prevent electrical noise generated on the outer side of the semiconductor device 1 from entering the hollow space S2 and reach the semiconductor chip 5. That is, it is possible to reliably prevent malfunction of the semiconductor chip 5 due to noise.

なお、上記の実施の形態では、分割工程において、ローラLを半導体ユニット65、保護部材P1及び抑え部材P2に対して移動させるとしたが、これに限ることはなく、例えば、ローラLに対して半導体ユニット65、保護部材P1及び抑え部材P2を移動させるとしても構わない。
また、基板用板材41の表面3a側にローラLの周面L1を下側から押し付けるとしたが、これに限ることはなく、例えば、図11に示すように、基板用板材41の表面3a側にローラLの周面L1を上側から押し付けるとしても構わない。なお、上記のように、ローラLを使用して分割工程を行う場合には、ローラLを保護部材P1上で転がして移動させるとしてもよい。
In the above embodiment, in the dividing step, the roller L is moved with respect to the semiconductor unit 65, the protective member P1, and the holding member P2. However, the present invention is not limited thereto. The semiconductor unit 65, the protection member P1, and the holding member P2 may be moved.
Further, although the peripheral surface L1 of the roller L is pressed from the lower side to the surface 3a side of the substrate plate 41, the present invention is not limited to this. For example, as shown in FIG. 11, the surface 3a side of the substrate plate 41 is provided. Alternatively, the peripheral surface L1 of the roller L may be pressed from above. As described above, when the dividing process is performed using the roller L, the roller L may be rolled and moved on the protective member P1.

さらに、分割工程における切り込み49a,49bの残部の破断方法は、ローラLを用いて基板用板材41を折り曲げることに限らない。すなわち、分割工程においては、例えば、基板用板材41のうち、上記切り込み49a,49bの両側に位置する一対のセラミック基板3を、基板用板材41の厚さ方向に関して相互に逆向きに移動させて切り込み49a,49bの残部にせん断応力を発生させることで、切り込み49a,49bの残部を破断する、としても構わない。   Further, the method of breaking the remaining portions of the cuts 49a and 49b in the dividing step is not limited to bending the board material 41 using the roller L. That is, in the dividing step, for example, the pair of ceramic substrates 3 located on both sides of the notches 49a and 49b in the substrate plate 41 are moved in opposite directions with respect to the thickness direction of the substrate plate 41. The remaining portions of the cuts 49a and 49b may be broken by generating shear stress in the remaining portions of the cuts 49a and 49b.

さらに、側壁部37は、天板部35の四辺からそれぞれ突出して設けられるとしたが、これに限ることはなく、少なくとも天板部35を挟み込む位置に一対形成されていればよい。すなわち、側壁部37は、例えば、天板部35のうち対角に位置する一対の角部のみに形成されるとしても構わない。また、例えば、図12,13に示すように、天板部35の全ての角部に側壁部71を形成するとしてもよい。
なお、上記のように、天板部35の四角に側壁部71を形成する場合には、例えば、図14,15に示すように、蓋体準備工程において、各蓋体7の側壁部71を天板部35の各角部に形成すると共に、基板用板材準備工程において、各側壁部71を挿入する各挿入穴72を切り込み49a,49bの交差部分に形成すればよい。なお、挿入穴72は、図12,13に示すように、セラミック基板3の各角部に形成される溝74を構成するものである。
Furthermore, although the side wall portions 37 are provided so as to protrude from the four sides of the top plate portion 35, the side wall portions 37 are not limited thereto, and a pair of the side wall portions 37 may be formed at least at positions where the top plate portion 35 is sandwiched. That is, the side wall portion 37 may be formed only on a pair of corner portions located diagonally on the top plate portion 35, for example. For example, as shown in FIGS. 12 and 13, side wall portions 71 may be formed at all corners of the top plate portion 35.
In addition, when forming the side wall part 71 in the square of the top plate part 35 as described above, for example, as shown in FIGS. In addition to being formed at each corner of the top plate portion 35, in the board material preparation step, each insertion hole 72 for inserting each side wall portion 71 may be formed at the intersection of the cuts 49a and 49b. The insertion holes 72 constitute grooves 74 formed at each corner of the ceramic substrate 3 as shown in FIGS.

さらに、上述のように、各挿入穴72を切り込み49a,49bの交差部分に形成する場合には、基板用板材準備工程において、図12〜14に示すように、切り込み49a,49bのうち上記交差部分から外れた位置に、外部接続端子19と同数のスルーホール73を形成すると共に、各外部接続端子19が各スルーホール73に接する位置に形成されるとしても構わない。
この構成の場合には、分割工程において切り込み49a,49bの残部を破断することでスルーホール73が分断されて、セラミック基板3の側面3bに露出する凹状溝75が形成されることになる。この凹状溝75は、半導体装置1をはんだにより実装基板(図示せず)に実装する際に、各外部接続端子19に対するはんだの濡れ性を向上させる効果を有する、すなわち、半導体装置1と実装基板との電気的な接続を確実に行うことが可能となる。
Furthermore, as described above, when the insertion holes 72 are formed at the intersections of the cuts 49a and 49b, in the board plate preparation process, as shown in FIGS. The same number of through holes 73 as the external connection terminals 19 may be formed at positions away from the portion, and each external connection terminal 19 may be formed at a position in contact with each through hole 73.
In the case of this configuration, the through hole 73 is divided by breaking the remaining portions of the cuts 49a and 49b in the dividing step, and the concave groove 75 exposed to the side surface 3b of the ceramic substrate 3 is formed. The concave groove 75 has an effect of improving the wettability of solder with respect to each external connection terminal 19 when the semiconductor device 1 is mounted on a mounting substrate (not shown) with solder, that is, the semiconductor device 1 and the mounting substrate. It is possible to make an electrical connection with the.

また、基板用板材41の切り込み49a,49bは、基板用板材41の表面3a及び裏面3cに形成されるとしたが、これに限ることはなく、例えば、基板用板材41の表面3aもしくは裏面3cの一方のみに形成されるとしても構わない。
さらに、半導体装置1や半導体ユニット65を構成するセラミック基板3や基板用板材41は、セラミック粉末を含有するペーストから形成されるとしたが、これに限ることはなく、少なくとも切り込み49a,49bの残部を容易に破断できる材料から形成されていればよい。すなわち、セラミック基板3や基板用板材41は、例えば、ガラスクロス入りの有機基板から形成されるとしてもよい。
Further, the notches 49a and 49b of the board material 41 are formed on the front surface 3a and the back surface 3c of the board material 41, but the present invention is not limited to this. For example, the front surface 3a or the back surface 3c of the board material 41 It does not matter even if it is formed only on one of these.
Furthermore, although the ceramic substrate 3 and the board | plate board material 41 which comprise the semiconductor device 1 and the semiconductor unit 65 were formed from the paste containing a ceramic powder, it is not restricted to this, At least remainder of notches 49a and 49b As long as it is formed of a material that can be easily broken. That is, the ceramic substrate 3 and the board material 41 may be formed from an organic substrate containing glass cloth, for example.

また、半導体装置1を製造する際には、基板用板材41を用いるとしたが、これに限ることはなく、予め固片化された個々のセラミック基板3にそれぞれ蓋体7を重ね合わせるとしても構わない。
この構成の場合でも、セラミック基板3に蓋体7を重ね合わせる際に、相対する一対の側壁部37,71をそれぞれセラミック基板3の溝9,74に収容することで、これら一対の側壁部37,71によりセラミック基板3を挟み込むことができる。したがって、セラミック基板3に対する天板部35の位置決めを容易に行うことができる、すなわち、セラミック基板3に対する蓋体7の位置決めを容易に行うことができる。
さらに、個々のセラミック基板3に溝9,74を形成しておくことにより、半導体装置1を製造する際に個々のセラミック基板3にそれぞれ蓋体7を重ね合わせる際に、溝9,74によって各側壁部37,71がセラミック基板3の側面3bに沿って移動することを規制できるため、セラミック基板3に対する側壁部37,71の位置決めを容易に行うことができる。
Further, the substrate material 41 is used when the semiconductor device 1 is manufactured. However, the present invention is not limited to this, and the lid body 7 may be superimposed on each ceramic substrate 3 that has been solidified in advance. I do not care.
Even in this configuration, when the lid body 7 is overlaid on the ceramic substrate 3, the pair of opposing side wall portions 37 and 71 are accommodated in the grooves 9 and 74 of the ceramic substrate 3, respectively. , 71 can sandwich the ceramic substrate 3. Therefore, the top plate part 35 can be easily positioned with respect to the ceramic substrate 3, that is, the lid 7 can be easily positioned with respect to the ceramic substrate 3.
Further, by forming the grooves 9 and 74 in the individual ceramic substrates 3, each of the grooves 9 and 74 allows the lids 7 to be superimposed on the individual ceramic substrates 3 when the semiconductor device 1 is manufactured. Since the side walls 37 and 71 can be restricted from moving along the side surface 3b of the ceramic substrate 3, the side walls 37 and 71 can be easily positioned with respect to the ceramic substrate 3.

また、蓋体7は、単純にセラミック基板3の溝9,74内に配される側壁部37,71を備えるだけではなく、例えば、図16に示すように、半導体チップ5の側方を囲繞可能な位置に複数の側壁部81を形成して構成されていてもよい。さらに、蓋体7は、例えば、図17に示すように、天板部35の周縁全体にわたって側壁部83を形成して構成されるとしても構わない。
これらの構成の場合には、半導体チップ5の側方が導電性を有する側壁部81,83によって覆われることになるため、半導体装置82,84の外方側において発生したノイズが半導体装置82,84の側方から侵入しようとしても、側壁部81,83においてノイズが中空空間S2に侵入することを防いで半導体チップ5に到達することを防止できる。したがって、ノイズに基づく半導体チップ5の誤作動を確実に防止することができる。
In addition, the lid body 7 includes not only the side wall portions 37 and 71 arranged in the grooves 9 and 74 of the ceramic substrate 3, but also surrounds the side of the semiconductor chip 5 as shown in FIG. A plurality of side wall portions 81 may be formed at possible positions. Furthermore, for example, as shown in FIG. 17, the lid body 7 may be configured by forming a side wall portion 83 over the entire periphery of the top plate portion 35.
In the case of these configurations, since the side of the semiconductor chip 5 is covered with the side walls 81 and 83 having conductivity, noise generated on the outer side of the semiconductor devices 82 and 84 is caused by the semiconductor devices 82 and 84. Even if it tries to enter from the side of 84, it is possible to prevent the noise from entering the hollow space S <b> 2 in the side walls 81 and 83 and to reach the semiconductor chip 5. Therefore, malfunction of the semiconductor chip 5 due to noise can be reliably prevented.

さらに、上記ノイズが半導体装置1の側方から中空空間S2に侵入することを防止する方法としては、上述したものの他、セラミック基板3の側面3bや溝9,74に、銅や銀等の導電性を有する導電性ペーストを塗布若しくは吹付を行うことが挙げられる。なお、この導電性ペーストの塗布若しくは吹付は、少なくとも蓋体7の側壁部37,71,81,83によって覆われないセラミック基板3の側面3bや溝9,74に行えばよい。   Furthermore, as a method for preventing the noise from entering the hollow space S2 from the side of the semiconductor device 1, in addition to the above, the side surface 3b and the grooves 9, 74 of the ceramic substrate 3 are electrically conductive such as copper and silver.
