Title: Etching method of silicon nitride film
Inventor: ENOMOTO TATSUYA
IPC: H01L21/306
Filed: 1978-11-21
Abstract: PURPOSE: To prevent breakage of a wire arranged through a hole at a silicon nitride film by implanting ion to the silicon nitride film, forming a mask on the film, etching the film to thereby reducing the angle of the opening at the etched film in its cross section.  
     CONSTITUTION: After a plasma CVD silicon nitride film 4 is formed on a substrate, ion 11 of Ar or the like is implanted on the entire surface of the film 4. After a photo resist 5 is coated as a mask on the film 4 except for the etched portion to be formed with a through hole 6, the film 4 is etched at the etched portion. Since the side 7 of the through hole 6 thus becomes rectilinear by the etching process and the angle α of the opening end 8 becomes larger than 90°C, it prevents breakage of a second layer wiring metal 9 formed after removing the photo resist 5, at the through hole due to its electromigration.

Title: Electron beam annealing method
Inventor: YAMAGISHI NAGAYASU
IPC: H01L21/263
Filed: 1985-07-03
Abstract: PURPOSE:To enable controlling the temperature gradient of the center and the end of a beam, to enable obtaining the optimum temperature distribution for recrystallization and to easily form a great-area recrystallization layer with few crystal defects by modulating at the end of the beam in the forming of a pseudo-linear beam. CONSTITUTION:An electron beam is scanned by fixing the scanning at near the vertexes of a triangular wave and the scanning is fixed at near one vertex for ta time and at near the other vertex for tb time. The distribution of a temperature at this time has a high temperature peak at the part of a semiconductor layer corresponding to both the ends of a linear beam and a low temperature trough at the center of the linear beam. Consequently, in this temperature distribution, recrystallization is started from the center which is the low temperature part of the melted region of the semiconductor layer and proceeds to the end of the linear beam according to the cooling of the melted region. This enables forming a great-area recrystallization layer with few crystal defects.
