Title: Manufacture of semiconductor device
Inventor: YAMAUCHI TSUNENORI
IPC: H01L21/76
Filed: 1989-03-07
Abstract: PURPOSE:To make an IC to be highly dense at low cost by making the concentration of conductive type impurity of a conductive type at the surface part of a substrate to that where an impurities diffusion layer can be formed up to the thickness which is nearly half that of an epitaxial layer. CONSTITUTION:An oxide film pattern 2 is formed on a p-type Si substrate 1, n<+>-type embedded layer 3 is formed by introducing arsenic, a thermal oxide film pattern 2 is eliminated, and then an n-type epitaxial layer 4 is allowed to grow. Then, the surface is oxidized for forming a window-opened oxide film pattern 5. And then, boron is diffused through the window and then impurities are diffused by nearly the same distance also from the substrate 1 into the epitaxial layer 4. Namely, the impurities are diffused by nearly the same ratio from the both sides of the epitaxial layer 4 and then isolation diffusion layer is formed by approximately 1/2 diffusion distance as compared with the case only from the surface. At this time, the impurities concentration of the Si wafer 1 is set to 3-15 times larger than that of the epitaxial layer 4. Thus, it is possible to reduce the area of element isolating region and make the IC to be highly dense at low cost.

Abstract: PURPOSE:To improve the efficiency of a laser device by housing a discharge part in a vacuum vessel and making a cross-sectional area small. CONSTITUTION:A microwave electric power 2 that is radiated by a microwave oscillator 1 is injected into an electric discharge part 5 in which a low pressure laser gas at several Torr is sealed through a partition 4.
