Abstract: PURPOSE: To obtain a fine pattern of high precision by selectively etching a covered layer formed on a semiconductor substrate surface while rising the temperature of the covered layer after making an opening by providing a mask layer which is proof against an etching agent for the covered layer.  
     CONSTITUTION: On semiconductor substrate 1, SiO 2  film 2, a covered layer, is adhered and a pattern of photo resist film 3 with opening 3a is formed on it in order to etch selectively the film. At this time the film thickness of layer 3 is fixed to 4000 to 8000Å and a photo process from pre-baking to development starts, but post- baking is done at 150 to 170°C for five minutes specially before etching in order to improve adhesion between layer 3 and film 2. Further, an etching solution uses an ammonium-fluoride solution and an etching process is carried out while rising the temperature to 35 to 45°C. As a result, the etching speed increases 4.0 to 5.0 times as high as that at 20 to 25°C, and fine opening 2a' can be obtained while shortening an etching time.

Abstract: PURPOSE:To certainly perform refresh within a period and, at the same time, to prevent decline of a processing speed by performing the refresh regardless of the refresh period whenever the vacant cycle of a bus is detected and, at the same time, setting a means which sets the refresh period to an initial state. CONSTITUTION:A vacant cycle detecting means 34 monitors the memory cycle of a data bus 11 and, when a vacant cycle is produced in the data bus 11, generates a memory cycle detect signal Mc.
