Title: Manufacture of semiconductor device
Inventor: OTA HIDEAKI
IPC: H01L21/302
Filed: 1990-11-05
Abstract: PURPOSE:To perform selective etching on the surface of a semiconductor substrate so as to reduce the etching time of the substrate by irradiating the semiconductor substrate with a large-size laser beam in a gaseous atmosphere through a mask which partially intercepts the laser beam. CONSTITUTION:A mask 2 is provided on the way of a collimated large-size argon laser beam l. The argon laser beam 3 passed through the mask 2 is made incident to a silicon substrate 4 placed in a Cl2 gas atmosphere. Thus the same etching pattern as the pattern of the mask 2 is formed on the substrate 1. Therefore, the device for etching the semiconductor substrate can be simplified, because the etching time can be reduced and the need of a complicated scanning mechanism can be eliminated.

Title: Window having synthetic resin frame and manufacture thereof
Inventor: OTAKE SHINICHI
IPC: B29C45/17
Filed: 1988-11-29
Abstract: PURPOSE:To prevent the breakage/deformation of a window plate and the production of a sink mark on an outer surface by providing an inside cavity on a frame portion, injecting a smaller quantity of synthetic resin than the cavity space capacity of a molding tool and injecting compressed air into the inside to carry out molding. CONSTITUTION:After placing a window plate 1 in a molding tool and clamping same, molten synthetic resin 2' of a quantity relatively smaller than the least capacity of a cavity space 12 is injected out of gates 13a-13c and filled. Then, as a chemically inert compression gas like air or N2 gas is injected, simultaneously with the injection of the synthetic resin depending on the kind of the resin, from the gates 13a-13c into briding-side corresponding places, the compression gas is advanced so as to spread the synthetic resin 2' injected into the space 12. Thus, since the synthetic resin 2' is uniformly pressed against all the inner faces of the space 12 and the edge faces of the plate 1 and allowed to flow to all the corners and hardened, no excessive pressure is applied to the edge face of the plate 1 preventing breakage while producing no sink mark, etc. on the outer surface of the frame portion 2.

Abstract: PROBLEM TO BE SOLVED: To provide a chuck device holding a thin work while suppressing its elastic deformation. SOLUTION: Chucks 70, 72, 74 hold different portions of a work 12 respectively when gear cutting machining is applied to the inner peripheral face 24 of the thin large-diameter section 22 of the work 12. The chuck 70 firmly holds the small-diameter section 26 of the work 12 with a collet 80, then the chuck 72 holds the large-diameter section 22 of the work 12 with a collet 140 via proper force, and finally the chuck 74 firmly holds the large-diameter section 22 of the work 12. The chuck 72 is kept at the holding state by the elastic force of a compression coil spring 268 applied to a taper member 160 via an action pin 262, thus the holding force is not made excessive. The contact section 290 of the moving contact member 200 of the chuck 74 is kept in contact with the tip face 258 of the work 12 to pinch the large-diameter section 22 from both sides together with a fixed contact member 156, thus the large-diameter section 22 is rarely elastically deformed.
