Title: Manufacture of semiconductor device
Inventor: MIENO FUTAMIKE
IPC: H01L21/76
Filed: 1984-04-03
Abstract: PURPOSE:To suppress the yield of bird beaks in separating elements and to make the width of the element separation small, by preliminarily forming a silicon nitride film on the element forming region of a silicon semiconductor and the side wall of a U-groove before burying the U-groove by a selective epitaxial growing method. CONSTITUTION:A U-groove 6 is formed in a silicon semiconductor base layer 1. Then the surfaces of the element forming region of the silicon semiconductor base layer 1 and the inside of the U-groove are coated by a silicon nitride film 8. Thereafter, the bottom part of the silicon nitride film 8 in the U-groove is selectively removed, and the silicon semiconductor base layer 1 is exposed. Then, a silicon semiconductor 10 is epitaxially grown in the U-groove selectively, and the U-groove 6 is buried. The surface of the silicon semiconductor 10 in the U-groove is oxidized 11. Even though the groove is buried by the selective epitaxial growing method and the surface is oxidized, the growth of the oxide film is stopped there owing to the presence of the nitride film.

IPC: H01L21/31
Filed: 1984-04-04
Abstract: PURPOSE:To enable the uniformity of film thickness and reduction in manufacturing time by a method wherein many blast nozzles and inhalants are arranged alternately in two dimensions. CONSTITUTION:When many of nozzle type reaction gas blast outlets 11 and inhalants 12 are made close to each other and alternately arranged above a substrate 13, the gas route over the substrate becomes much shorter than the case of a normal CVD device. Besides, these nozzles are arranged in two dimensions in parallel with the substrate plane. Here, numerals 21 represent the blast nozzle; X marks 22 represent the inhalants; and arrows 23 represnet gas routes. In case of need for improving the film thickness distribution at intervals of nozzle arrangement capable of being processed, it becomes necessary to suitably move the nozzle position or substrate position along the substrate surface during CVD. In this case, it is advisable that revolutions drawing circles on the substrate surface are given to the section composed of the spouts and the inhalants so that the radius of this revolution may be 1/4-4/4 of the distance L between adjacent outlets and inhalants.
