Description

本発明は、ステージ上に半導体基板等の電子部材を搬送する搬送装置、電子部材の載置方法、及び半導体装置の製造方法に関する。特に本発明は、ステージ上に載置する際の電子部材の位置精度を高くすることができる搬送装置、電子部材の載置方法、及び半導体装置の製造方法に関する。   The present invention relates to a transport device that transports an electronic member such as a semiconductor substrate onto a stage, a method for placing the electronic member, and a method for manufacturing a semiconductor device. In particular, the present invention relates to a transfer device, a method for placing an electronic member, and a method for manufacturing a semiconductor device that can increase the positional accuracy of an electronic member when placed on a stage.

図6は、従来の搬送装置が有するステージの構成を説明する為の平面図である。この搬送装置は、ステージ110上に電子部材101(例えば半導体チップ又は半導体基板)を載置する装置である。ステージ110には電子部材101を吸着するための吸着穴111が設けられている。吸着穴111は、電子部材101の縁と重ならないように、縁より内側に配置されている。   FIG. 6 is a plan view for explaining a configuration of a stage included in a conventional transfer apparatus. This transfer device is a device for placing an electronic member 101 (for example, a semiconductor chip or a semiconductor substrate) on a stage 110. The stage 110 is provided with a suction hole 111 for sucking the electronic member 101. The suction hole 111 is disposed inside the edge so as not to overlap the edge of the electronic member 101.

電子部材101は、搬送トレイ(図示せず)を用いて搬送装置のそばまで運ばれる。そして電子部材101は、搬送用の吸着治具(図示せず)を用いて搬送トレイから取り出されて搬送され、ステージ110上に載置される。ステージ110上に載置された電子部材101は、吸着穴111によって吸着される。   The electronic member 101 is transported to the vicinity of the transport device using a transport tray (not shown). The electronic member 101 is taken out from the transfer tray using a transfer suction jig (not shown), transferred, and placed on the stage 110. The electronic member 101 placed on the stage 110 is sucked by the suction hole 111.

電子部材101の搬送トレイ内での位置には、搬送時の振動等に起因したばらつきが生じる。吸着治具では電子部材101の位置が補正できないため、ステージ110上に載置された電子部材101の位置には、ばらつきが生じる。従来は、この位置のばらつきを機械的に修正していた(例えば特許文献1参照)。
特開平7−211733号公報(第3段落)
Variations in the position of the electronic member 101 in the transport tray are caused by vibrations during transport. Since the position of the electronic member 101 cannot be corrected by the suction jig, the position of the electronic member 101 placed on the stage 110 varies. Conventionally, this variation in position has been mechanically corrected (see, for example, Patent Document 1).

発明を実施するための形態BEST MODE FOR CARRYING OUT THE INVENTION

以下、図面を参照して本発明の実施形態について説明する。図1は、本発明の第1の実施形態に係る搬送装置の構成を説明する為の概略図である。本搬送装置は、半導体チップをTCP(tape carrier package)技術で実装する装置の一部である、吸着治具20及びステージ10を有している。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic view for explaining the configuration of a transport apparatus according to the first embodiment of the present invention. The present transport device includes a suction jig 20 and a stage 10 which are a part of a device for mounting a semiconductor chip using a TCP (tape carrier package) technology.

本搬送装置で搬送される半導体チップ1は、搬送トレイ2を用いて搬送装置のそばまで搬送される。このとき、搬送トレイ2と半導体チップ1の間には遊びがあるため、搬送トレイ2内における半導体チップ1の位置には、搬送時の振動等に起因したばらつきが生じる。   The semiconductor chip 1 transported by the transport device is transported to the side of the transport device using the transport tray 2. At this time, since there is play between the transport tray 2 and the semiconductor chip 1, the position of the semiconductor chip 1 in the transport tray 2 varies due to vibration or the like during transport.

搬送装置のそばまで搬送された半導体チップ1は、搬送装置が有する搬送用の吸着治具20によって搬送トレイ2から取り出される。吸着治具20には吸着穴21が設けられている。半導体チップ1は、吸着穴21に吸着されることにより、搬送トレイ2から取り出される。吸着治具20に吸着された状態において、半導体チップ1の位置は、ばらついたままである。   The semiconductor chip 1 transported to the vicinity of the transport device is taken out from the transport tray 2 by the transport suction jig 20 included in the transport device. A suction hole 21 is provided in the suction jig 20. The semiconductor chip 1 is taken out from the transport tray 2 by being sucked into the suction holes 21. In the state of being sucked by the suction jig 20, the position of the semiconductor chip 1 remains varied.

その後、半導体チップ1は、吸着治具20によってステージ10上まで搬送され、その後吸着治具20から離れる。これにより、半導体チップ1はステージ10上に載置される。ステージ10には複数の吸着穴11が設けられている。吸着穴11は排気手段(図示せず)に接続されている。吸着穴11に吸着されることにより、半導体チップ1は位置決めされる。その後、半導体チップ1には実装処理が行われる。   Thereafter, the semiconductor chip 1 is transported to the stage 10 by the suction jig 20 and then leaves the suction jig 20. Thereby, the semiconductor chip 1 is placed on the stage 10. The stage 10 is provided with a plurality of suction holes 11. The suction hole 11 is connected to an exhaust means (not shown). The semiconductor chip 1 is positioned by being sucked into the suction holes 11. Thereafter, a mounting process is performed on the semiconductor chip 1.

図2は、吸着穴11の位置を説明する為のステージ10の平面図である。吸着穴11は、略長方形の半導体チップ1が有する4つの角それぞれに対応する位置に設けられている。このため、半導体チップ1は、4つの角それぞれが、対応する吸着穴11上に位置した状態で位置決めされる。   FIG. 2 is a plan view of the stage 10 for explaining the position of the suction hole 11. The suction holes 11 are provided at positions corresponding to the four corners of the substantially rectangular semiconductor chip 1. For this reason, the semiconductor chip 1 is positioned in a state where each of the four corners is positioned on the corresponding suction hole 11.

このように、本実施形態によれば、ステージ10が有する吸着穴11を、半導体チップ1が有する4つの角それぞれに対応する位置に配置したため、半導体チップ1にはセルフアライメント効果が生じる。このため半導体チップ1は、4つの角それぞれが、対応する吸着穴11上に位置した状態で位置決めされる。   As described above, according to the present embodiment, the suction holes 11 of the stage 10 are arranged at positions corresponding to the four corners of the semiconductor chip 1, so that the semiconductor chip 1 has a self-alignment effect. For this reason, the semiconductor chip 1 is positioned in a state where each of the four corners is positioned on the corresponding suction hole 11.

従って、ステージ10に載置する際の半導体チップ1の位置精度が向上し、機械的な位置修正作業を行う必要がなくなる。この効果は、半導体チップ1が小型であり、搬送トレイ2内での位置のばらつきが大きくなる場合に顕著になる。   Therefore, the positional accuracy of the semiconductor chip 1 when placed on the stage 10 is improved, and there is no need to perform a mechanical position correcting operation. This effect becomes prominent when the semiconductor chip 1 is small and the position variation in the transport tray 2 becomes large.

Hereinafter, the description of the same configuration as that of the first embodiment is omitted.
