Title: Position detection method for semiconductor substrate and semiconductor substrate and photomask
Inventor: MIYATAKE TSUTOMU
IPC: H01L21/027
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To reduce influence of variation in a step form by forming an alignment mark of protruded and recessed parts having flat surface form smaller than resolution of a lens. SOLUTION: Consists of recessed areas and protruded areas where alignment marks are alternately wired. Width A and pinch B are smaller than the resolution of a lens of an observation optical system. So the light intensity at the inside C of the alignment mark is weaker than the surrounding light intensity, thus the light intensity distribution in which the inside C of the alignment mark is a valley is obtained. And, even when there is variation in the step formation of the alignment mark formed on a wafer surface or thickness of a resist film formed on the alignment mark, relatively accurate position detection is possible.

Abstract: PURPOSE:To make effective the program control of the injection speed of an injection molder and to reduce the delay of time of the moving speed of a screw ram, by using the variable discharge amount property corresponding to the load flow rate of a variable discharge amount hydraulic pump and the high response of a hydraulic servo-pump. CONSTITUTION:In program-controlling the moving speed of a screw ram 1 of a plastic injection molder, when the moved position of the screw ram 1 of the injection moder reaches a little before the prodetermined speed change position, the discharge amount of a variable discharge amount hydraulic pump 5 is changed. Then when the moved position of the screw ram 1 reaches the predetermined speed change position, the opening thereof is changed by a hydraulic serve-valve 3 thereby allowing high response time of the hydraulic servo-valve 3, and the variable discharge amount hydraulic pump 5 is used to discharge the required amount of an oil to control the hydraulic servo-valve 3. Thus although the control of the hydraulic serve-pump 3 that additionally uses the variable discharge amount hydraulic pump 5 can be controlled, if a computer is used it will be more effectively carried out.
