Description

本発明は、ウエーハが貼着された粘着テープを拡張してウエーハに外力を付与するためのテープ拡張装置に関する。   The present invention relates to a tape expansion device for expanding an adhesive tape to which a wafer is attached and applying an external force to the wafer.

半導体デバイス製造工程においては、略円板形状である半導体ウエーハの表面に格子状に配列されたストリートと呼ばれる分割予定ラインによって複数の領域が区画され、この区画された領域にIC、LSI等のデバイスを形成する。そして、半導体ウエーハをストリートに沿って切断することによりデバイスが形成された領域を分割して個々のデバイスを製造している。また、サファイヤ基板の表面に窒化ガリウム系化合物半導体等が積層された光デバイスウエーハも所定の分割予定ラインに沿って切断することにより個々の発光ダイオード、レーザーダイオード等の光デバイスに分割され、電気機器に広く利用されている。   In the semiconductor device manufacturing process, a plurality of regions are partitioned by dividing lines called streets arranged in a lattice pattern on the surface of a substantially wafer-shaped semiconductor wafer, and devices such as ICs, LSIs, etc. are partitioned in the partitioned regions. Form. Then, the semiconductor wafer is cut along the streets to divide the region in which the device is formed to manufacture individual devices. In addition, an optical device wafer in which a gallium nitride compound semiconductor or the like is laminated on the surface of a sapphire substrate is also divided into optical devices such as individual light-emitting diodes and laser diodes by cutting along a predetermined division line. Widely used.

上述した半導体ウエーハや光デバイスウエーハ等の被加工物を分割する方法として、その被加工物に対して透過性を有する波長のパルスレーザー光線を用い、分割すべき領域の内部に集光点を合わせて照射し、被加工物の内部にストリートに沿って変質層を連続的に形成し、この変質層が形成されることによって強度が低下したストリートに沿って外力を加えることにより、被加工物を分割する方法が実用化されている。(例えば、特許文献1参照。)   As a method of dividing a workpiece such as the semiconductor wafer or the optical device wafer described above, a pulse laser beam having a wavelength that is transparent to the workpiece is used, and a focusing point is set inside the region to be divided. Irradiate and continuously form a deteriorated layer along the street inside the workpiece, and split the workpiece by applying external force along the street whose strength has decreased due to the formation of this deteriorated layer. The method to do is put into practical use. (For example, refer to Patent Document 1.)

そして、変質層が形成されることによって強度が低下したストリートに沿って外力を付与する技術として、ウエーハが貼着された粘着テープを拡張し、その後、粘着テープを拡張した状態で環状のフレームを個々のデバイスに分割されたウエーハを囲繞して粘着テープに貼着する技術が下記特許文献2に記載されている。   Then, as a technique for applying external force along the street where the strength has decreased due to the formation of the altered layer, the adhesive tape with the wafer attached is expanded, and then the annular frame is expanded with the adhesive tape expanded. A technique for surrounding a wafer divided into individual devices and sticking it to an adhesive tape is described in Patent Document 2 below.

Then, there is a problem that the individual divided devices that are stuck to the adhesive tape are damaged. Moreover, there is a problem that the adhesive tape does not expand sufficiently if the two opposite sides are pulled with the two orthogonal sides sandwiched.
