Title: Manufacture of semiconductor device
Inventor: MITSUMOTO KAZUFUMI
IPC: H01L29/732
Filed: 1984-07-21
Abstract: PURPOSE:To achieve formation of insulation ilm to the one electrode surface and patterning with a simple process on the occasion of sufficiently narrowing the interval of respective electrodes to be provided in different conductivity type region. CONSTITUTION:A P type collector layer 2, a N type base layer 3, a P type emitter layer 4 and electrode windows 6, 7 are formed on a Si substrate 1. A resist mask 9A is selectively formed by vacuum deposition of Al 9 and it is excessively etched arbitrarily, forming an eave 10 in the length l at the lower part part of mask 9A. Next, when the electrode 11A and Al films 11B, 11C are formed at the window 7 by vacuum deposition of Al, a gap 12 of width lis formed between the electrodes 8A and 11A. The Al film 11B is removed together with the resist 9A. If necessary, the Al film 11C is also removed simultaneously. According to this structure, an electrode interval can be remarkably narrowed as compared with the conventional method. Formation of insulation film on the first electrode film 5, patterning and masking are no longer necessary and thereby the processings are simplified by that much.
