Abstract: PROBLEM TO BE SOLVED: To enable minimization of the increase of the number of steps by an easy method and protection of a rear side of a semiconductor substrate from contaminated metals such as Cu, upon formation of an element isolation region by an STI(shallow trench isolation) method. SOLUTION: A silicon oxide film 2 and a silicon nitride film 3 are formed on the front and rear surfaces of a semiconductor substrate 1. The silicon nitride film 3, silicon oxide film 2 and semiconductor substrate 1 are etched sequentially with the use of a photoresist 4 to make a groove pattern and embed a silicon oxide film 5 therein. A silicon oxide film 9 is formed on the front and rear surfaces. The surface is planarized, until the silicon nitride film 3 is exposed by a CMP(chemical mechanical polishing) technique. The resultant substrate is immersed in phosphoric acid solution to remove the silicon nitride film 3 on the front surface. An HF aqueous solution or the like, having a low concentration, is used to remove the silicon nitride film 2 on the front surface.  At this time, the silicon oxide film 9 on the rear surface is removed, but the silicon nitride film 3 on the rear surface is not removed, and the rear surface is covered with the silicon oxide film 2 and the silicon nitride film 3.

Title: Storage device
Inventor: OUCHI MICHIO
IPC: G11C11/34
Filed: 1985-09-30
Abstract: PURPOSE:To shorten the time needed for discrimination of information and also to prevent malfunction, by reducing the difference between the reference voltage and the voltage of a memory node when a detecting means detects the start of access to a memory cell. CONSTITUTION:The voltage difference between nodes VS and VS' is large before the base voltages VB and VB' of an accessed memory cell start their drops. Then a cell selection switching circuit 21 delivers the signal of a high level. Therefore, a reference voltage generating circuit 22 sets the reference voltage VR at a level lower by a fixed degree than the voltage VB'. When access is started and the difference of voltage between nodes VS and VS' is reduced, the circuit 21 delivers the signal of a low level. Thus the voltage VR starts rising and therefore the drop of both VB and VB' is started. Then the voltage VB' crosses immediately the voltage VR and a sense amplifier circuit 16 starts its discriminating action. When this discriminating action is through, the difference between VS and VS' is increased again. Thus the voltage VR is dropped again.

Abstract: PURPOSE: To realize an efficient operation by a constitution wherein only one converter is operated at the time of powering and when the current of an invertor reaches a predetermined level, the operation is stopped and the other converter is started to drive an invertor. CONSTITUTION: When a converter 31 and a chopper are started, a converter 31 performs DC voltage control and a chopper performs current control of the converter 31 which is operated with 10% current. An invertor then starts the powering operation and the current of the chopper decreases depending on the load current. When the load current reaches 10% of rated value, the current of the chopper goes zero and a stop command is delivered from a converter coordination monitor. When the load current reaches 20% of rated value, a hysteresis comparator 25 delivers a start signal and upon starting a converter 3, a two group operating state signal of converter is delivered to the current balance circuit of the converter 3, 31. Consequently, a switch is turned to the second gain circuit side thus realizing an efficient operation.
