Title: Production of liquid crystal display element
Inventor: HASEGAWA TAKESHI
IPC: G02F1/13
Filed: 1984-10-16
Abstract: PURPOSE:To part an original plate for a liquid crystal cell to a rectangular strip shape by disposing the original plate between a pair of vertically movable rollers and moving alternately and vertically the upper and lower rollers. CONSTITUTION:The original plate 7 for the liquid crystal cell are disposed between a pair of the vertically movable rollers 3 and 5. The one roller 3 or 5 is vertically moved to push the surface on one side of the plate 7 toward the other roller 5 or 3 to crack the surface on one side of the plate 7 and thereafter the other roller 3 or 5 is vertically moved to press the surface on the opposite side of the plate 7 to the other roller 5 or 3 thereby parting the original plate to the rectangular strip shape. The plate 7 is thus parted to the rectangular strip shape simply by moving alternately and vertically the rollers 3 and 5. There is no need for turning over the plate 7 and resetting the same in the midway of the parting. The time required for the parting operation is thus reduced and the working efficiency is improved.

IPC: H01L21/302
Filed: 1985-10-02
Abstract: PURPOSE:To restrain the dispersion of plasma processing against each wafer by providing a wafer susceptor on which the wafers are so placed that the interval dimension between the wafers is larger in the slow speed of processing gas flow than in the fast speed of the processing gas flow. CONSTITUTION:In a chamber 1, the flow speed of a processing gas is faster near A the inlet 2 of the gas and near C the exhaust port 3 than near B. A wafer suspector 80 is so constructed that the interval between wafers is narrow near A and C and wide near B and the flow speed of the processing gas between the wafers near A, C is restricted and the flow of the processing gas between the wafers near B is accelerated. For this reason, the flow speed of the processing gas between the wafers on the susceptor 80 is made uniform. This also makes the speed of removing the photo resist applied on the surface of each wafer uniform.
