Title: Center position detecting circuit
Inventor: SUGITA SUSUMU
IPC: G06F7/74
Filed: 1986-12-08
Abstract: PURPOSE:To shorten the processing time with a center position detecting circuit by inverting the logical levels of input signals at the positions following the terminal that detected first logical level '1' and coding the position of the terminal where the logical level '1' first emerges when viewed from the end at one side. CONSTITUTION:A 1st encoding circuit 7 converts the position where logical level '1' emerges first when viewed from the end at one side of a train of input terminals 1-6 into an address code. An inverting circuit 8 receives the output from the circuit 7 and inverts logically all input signals following the position where the logical level '1' is first detected. The output of the circuit 8 is supplied to a 2nd encoding circuit 9 and the position where the logical level '1' emerges first when viewed from the end at one side of an input terminal train. This position is converted into an address code. The address codes delivered from both circuits 7 and 9 are supplied to an addition circuit 10 and added together. These added outputs are supplied to a division circuit 11 and divided by 2. Thus a center position is obtained and outputted through an output terminal 12. In such a way, the processing time is shortened with a center position detecting circuit.

The Si substrate 1, in which the groove is formed, is inputted into saturated solution of oxalic acid, and anodic oxidation is performed. Thus a film with a thickness of 25nm is formed. Then, the thickness of the oxide film at the steep protruding corner part becomes about 1.5-2 times the normal thickness of the other part. An anodic oxide film 6 is removed with fluoric acid. Thereafter, a thermal oxide film and a polycrystalline Si electrode are formed on the surface of the Si substrate. Thus the breakdown strength equivalent to the case, in which a similar MOS capacitor is formed, is obtained.
