Title: Semiconductor device and manufacture thereof
Inventor: YOSHIKAWA KOICHI
IPC: H01L27/04
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To suppress the variation of contact resistance of a polysilicon resistance layer. SOLUTION: A nitride film 105 is formed on a polysilicon resistance layer 103, and an insulating film 106 is formed on the nitride film. A contact-hole 108 is formed through the insulating film and the nitride film. During the formation of the contact-hole by plasma etching, the nitride film suppresses the over- etching damage to the polysilicon resistance layer due to the difference of etching rate between the nitride film and the insulating film so that the variation of the contact resistance can be suppressed.

Filed: 1985-06-27
Abstract: PURPOSE:To reduce considerably the number of times of recording to record a half-tone picture in a high speed by recording the half-tone picture as a combination of bit plane density pictures. CONSTITUTION:When N-number of density gradations (N=16) are obtained, an input picture signal is decomposed into 4-bit bit plane pictures.
