Title: Pretreatment of semiconductor wafer
Inventor: HAMAGISHI KENJI
IPC: H01L21/304
Filed: 1990-08-17
Abstract: PURPOSE:To prevent a warpage from being generated in a wafer by a method wherein a groove-shaped notch is engraved in a scheduled scribing line or a scribing line on the side of a work processing surface of the raw wafer or the wafer prior to a wiring process, then, the notch engraving process is transferred to an element formation process or the wiring process. CONSTITUTION:A notch 2 is cut in a scribing line of a wafer 1 prior to a wiring process, that is, in an insulating film 4 and thereafter, a wiring 5 is provided. In case the notch is applied to a wafer of a diameter of 6-sun (about 20cm), the size of the notch is set in a width of 25mum and a depth of 10mum and a dicing machine may be used. In the case of a raw wafer, the notch is cut in a scheduled scribing line on the side of a work processing surface of the wafer and in the case of the wafer prior to the wiring process, the notch is cut in a scribing line on the side of the work processing surface of the wafer, whereby it becomes possible that a stress which is generated in the wafer in a work processing is dispersed and the generation of a warpage can be eliminated. As the notch which is engraved in the side of the work processing surface of the wafer, a groove-shaped notch of a width of 25mum or thereabouts and a depth of 10mum or thereabouts is desirable. When the depth exceeds 10mum, there is a possibility that the wafer is broken. Thereby, a warpage can be prevented from being generated during a process processing.

Title: Drawing device using electron rays
Inventor: KAWASAKI KATSUHIRO
IPC: H01L21/30
Filed: 1984-10-17
Abstract: PURPOSE:To contrive reduction in distortion caused by electrostatic deflection by providing an aligner between an electrostatic deflector and a projecting lens and performing alignment so as to make electron rays pass through the center of electrostatic deflection. CONSTITUTION:Mark positions X0 and Y0 are obtained by scanning a mark 17 with electron rays using an electromagnetic deflector 16 with a change-over switch 13 set on the side 1 using a CPU14 and 0V applied to an electrostatic deflector 15. In this time, the electron rays are not deflected by the electrostatic deflector 15 but pass through between the electrostatic deflector straightly. Next, when both electrodes of the electrostatic deflector 15 are applied with -V volt, an equi-potential line 18 is produced and the electron rays 19 are deflected as shown by the solid line to produce difference of DELTAL. The mark positions X0 and Y0 are shifted to X0+DELTALX and Y0+DELTALY respectively. If the electron rays are made to pass through the center of the electrostatic deflector 15 using an aligner 12, even if the both electrodes are applied with -V volt, the electron rays are not deflected and the difference DELTAL between the mark positions is assumed to be minimized. Accordingly, if the electron rays continue to be subjected to alignment by the aligner 12, they can pass through the center of the electrostatic deflector 15.
