Title: Semiconductor device and manufacturing method thereof
Inventor: YAMAGUCHI NORITOSHI
IPC: H01L29/78
Filed: 1992-02-26
Abstract: PURPOSE:To avoid the decrease in the manufacturing yield by a method wherein an insulating layer, the first and second semiconductor layers are formed at almost the same temperature so that the manufacturing process time may be cut down while preventing the pollutant adhering to any jig, etc., in the preceeding step from peeling in the next step. CONSTITUTION:The silicon nitride layer of an insulating layer 3, the first and second semiconductor layers 5 are respectively formed at the film formation temperature of 300-500 deg.C. At this time, P type impurities such as boron, etc., are contained in the first semiconductor layer 4 and then the Fermi level of the first semiconductor layer 4 is moved to almost the central part between the filled up band of an optical band gap and a conductor so as to provide a semiconductor device with excellent characteristics. Thus, the stand-by time for adjusting the substrate temperature to that in the next step can be eliminated when respective layers are formed thereby enabling the manufacturing process time to be cut down. Furthermore, the pollutant adhering to any jig, etc., in the preceeding step is to be prevented from peeling in the next step thereby enabling the decrease in the manufacturing yield to be avoided.
