Inventor: ISHII KAZUAKI
IPC: H01L21/76
Filed: 1987-06-19
Abstract: PURPOSE:To reduce the area of isolated region while facilitating the filling of an isolating groove with an insulator by a method wherein the groove is formed to isolate a laminated structure from the surface layer to the lowermost layer and then an inert region is formed in the semiconductor layers below the groove by ion implanting process. CONSTITUTION:Respective semiconductor layers to manufacture an HBT are successively coated with an implanting mask 13 and a mask 14 to form a resist pattern 15 with an opening made in an interelement isolating region. A common opening is made in respective layers 11-14 using the resist pattern 15 as a mask. First, a V-shape groove is formed in the semiconductor layers by ion milling process. Second, an inert region 16 is formed in the semiconductor layers below the V-shape groove by ion implanting process. Third, the layers 14, 13 are lifted off using the resist 12. Finally, an insulator is deposited until the V-shape groove is filled therewith by CVD process and then the insulator is thickly coated with resist so that an SiNx 10 only may be left in the V-shape groove using the filling process to flatten the substrate.
