Title: Mask program type read-only memory
Inventor: NISHIO YOSHINOBU
IPC: H01L21/8246
Filed: 1990-01-19
Abstract: PURPOSE:To improve an ion implantation region in shape around a memory cell and to enable the memory cell to output stably by a method wherein diffusion layers of the same isolation width as that of diffusion layers provided inside the memory cell are provided around the memory cell. CONSTITUTION:A diffusion layer 161 having no direct relation to the circuit operation of a memory cell is provided. Diffusion layers are provided around the memory cell at the same isolation width a with diffusion layers 103 and 104 provided inside the memory cell at an isolation width a. The thickness f of a resist film 170 at the peripheral boundary of the memory cell is equal to that of a resist film on the diffusion layers inside the memory cell, so that the resist film concerned has no adverse effect on the shape of an implantation region in a program code ion implantation process. As mentioned above, a diffusion layer isolating oxide film adjacent to memory cell transistors 121-158 is made constant in width 9 and a resist film formed on the diffusion layers inside the memory cell is formed uniform in thickness, so that an output is hardly inverted even at the peripheral part of the memory cell. By this setup, an ion implantation region can be improved in shape and a stable output can be obtained.

Filed: 1988-01-21
Abstract: PURPOSE:To improve high-frequency characteristic by making up the cross area in the wiring cross part formed by stacking substrates so as to be smaller than the cross area formed by crossing conductive parts of a predetermined line width to reduce the mismatch of a characteristic impedance. CONSTITUTION:In a multilayer interconnection substrate made up by stacking two or more substrate 3, 4 in which conductive parts 3b, 4b formed of a predetermined line width are disposed, a cross area 8 in the wiring cross part B, C formed by stacking substrates and conductive parts 3b, 4b of a predetermined line width are made up so as to be smaller than the cross area formed by intersection. That is, the line width forming the cross parts B, C between conductive parts 3b, 2b and conductive part 4b is made small. A small cross area in this manner enables the electrostatic capacity in the cross parts B, C between conductive parts 3b, 4b to be reduced, thereby preventing a mismatch of characteristic impedance and crosstalks.
