IPC: H01L21/3065
Filed: 1983-06-16
Abstract: PURPOSE:To prevent the increase of resistance values and the disconnection by elimination of a recess during formation of a wiring layer later by a method wherein a double taper is formed by forming an impurity layer of different etching rates in the surface of an SiO2 layer. CONSTITUTION:The SiO2 is formed on a substrate 1, and a PSG layer 2a is attached to the surface thereof to a depth of about the 1/4 of the thickness of the layer 2. Next, anisotropic etching is carried out with a resist layer 5 as a mask so that the side surface inclines by creeping to the peripheral edge of the layer 5. Further, the layer 2 is anisotropically etched to a depth of about the half. At this time, the etching rate of the layer 2 newly etched becomes lower in the lower direction. Accordingly, the double tapered surface is formed so that the taper angle becomes smaller from the boundary between the PSG layer 2a and the layer 2 toward the side of the substrate 1.

Abstract: PURPOSE:To prevent generation of halation by making a mesh electrode consist of a strand whose cross section is semicircular, facing the semicircular section to the phosphor screen side, and forming a concave at the flat section on the electron gun side. CONSTITUTION:One primary surface 211 of a glass substrate 21 is mirror-surface- lapped and a chrome coat is formed. This glass substrate 21 is mounted in a  vacuum container and a master mesh 22 is formed by the electron beam plotting method.
