Inventor: ARIGA KOICHI
IPC: H02M3/28
Filed: 1988-10-22
Abstract: PURPOSE:To protect a load from overvoltage by providing an apparatus with a rectifier and smoothing circuit obtaining DC voltage proportional to a secondary side output with a polarity reverse to that of an auxiliary power supply from a primary side auxiliary winding and by outputting an overvoltage sensing signal stopping a driving pulse, when said DC voltage exceeds a specified overvoltage set value. CONSTITUTION:Rectifier and smoothing circuits 22, 24 added to a primary side auxiliary winding 60 for an auxiliary power supply Vcc are supplied with DC voltage VB with a polarity reverse to that for said auxiliary power supply Vcc, and said DC voltage VB is proportional to a secondary side output voltage VO so as to operate as the overvoltage sensing voltage for said secondary side output. Then, when said DC voltage VB exceeds a specified overvoltage set value, said circuits 22, 24 output an overvoltage sensing signal to the overvoltage protection circuit 52 of a switching control IC 50 to stop a driving pulse outputted from said switching control IC 50 to a switching transistor 14. Thus, a load can be protected from overvoltage.

IPC: H01L21/306
Filed: 1987-10-20
Abstract: PURPOSE:To etch with good controllability by alternately impregnating a silicon plate with strong oxidizing solution and oxide film removing solution, and repeating the oxidation of the surface layer of the plate and the removal of the oxide film. CONSTITUTION:A silicon plate 1 is alternately impregnated with strong oxidizing solution 3 and oxide film removing solution 4, and the surface layer is controlled in thickness of 50Angstrom  or less by repeating the oxidation of the surface layer of the plate 1 and the removal of the oxide film. Thus, when the oxidation of the silicon film and the removal of the oxide film are separately performed, the etching of high controllability can be conducted. First, a silicon film is dipped in the solution containing only nitric acid to form an oxide film layer on its surface, the thickness of the formed oxide film is determined by the concentration and the temperature of the nitric acid in the order of several tens Angstrom . Then, the oxide film is removed with fluoric acid. The selectivity of etching the silicon and the oxide film with the fluoric acid is very high, and only the oxide film is etched. As a result, the silicon film can be uniformly etched with the controllability of several tens Angstrom .
