Title: Semiconductor wafer processing method
Inventor: WAKAHARA MASATOSHI
IPC: B23K26/364
Filed: 2018-07-10
Abstract: To provide a semiconductor wafer processing method capable of removing an altered layer and a strained layer without adding a mask layer forming step after a laser processing groove is formed and before a semiconductor wafer is divided.SOLUTION: There is provided a semiconductor wafer processing method comprising a laser processing groove forming step, a mask layer forming step, a first etching step, a second etching step, and a dividing step. The laser processing groove forming step forms a laser processing groove by exposing a semiconductor wafer by partly removing the semiconductor wafer, a protection layer, and a functional layer. The mask layer forming step covers regions except regions on a metal electrode in a residual protection layer in a region other than the laser processing groove. The first etching step exposes the metal electrode by subjecting the protection layer to plasma etching using a first gas via the mask layer. The second etching step expands the laser processing groove by subjecting the laser processing groove to plasma etching using a second gas via the mask layer after the first etching step. The dividing step divides the semiconductor wafer into device chips along the laser processing groove expanded by the second etching step.SELECTED DRAWING: Figure 8

IPC: A63F7/02
Filed: 2018-07-26
Abstract: PROBLEM TO BE SOLVED: To provide a game machine that does not give a player unpleasant feeling due to soil on a glass plate.SOLUTION: When a soil check control process is started, a peripheral control MPU automatically determines on the basis of a detection signal from a distance measurement sensor SA whether the glass plate of a glass unit has been soiled or not. If the glass plate of the glass unit has been soiled as a result of this determination, the result can be notified. A hall assistant or the like who noticed the notification is able to wipe off the soil on the glass plate of the glass unit. Thus, hand print is removed from the glass plate of the glass unit. This prevents a player from giving up an attractive pachinko game machine in unsanitary condition due to hand print and moving to another pachinko game machine or from patiently playing a game on a pachinko game machine in unsanitary condition.SELECTED DRAWING: Figure 164
