Title: Manufacture of semiconductor device
Inventor: SHIBUYA TAKAHIRO
IPC: H01L21/301
Filed: 1985-11-12
Abstract: PURPOSE:To restrain crack generation and increase dicing yield, by covering dicing lines with a resin film in the case of dicing of a semiconductor wafer, and cutting the wafer along the lines through the coating film. CONSTITUTION:When a polyimide resin coating film 3 is formed on semiconductor chip region 1 surround by a dicing line region 2, the coating film 3 is provided also on the dicing line region 2. In the case of cutting the semiconductor wafer along the line region 2, the wafer is cut through the coating film 3 by pressing down a dicing blade on the line of the region 2. In this manner, cracks and breaks toward the inner part of the region 1 can be prevented by virtue of the adhesion function of the coating film 3, so that the yield is improved and the increase of dicing speed is also enabled.

Abstract: PURPOSE:To improve the reliability and maintenance performance of a sensor and the titled equipment by providing an original detecting sensor supervisory device supervising deterioration of an original detection sensor. CONSTITUTION:In using a facsimile equipment, a control circuit 3 turns off a light emitting diode 1 at each communication, after a detection circuit 5 detects turning-off of a photo transistor (TR)4, the diode 1 is turned on again to start a timer 6.
