Title: Manufcture of semiconductor device
Inventor: ARIMA YASUO
IPC: H01L21/306
Filed: 1979-07-31
Abstract: PURPOSE:To enable the patterning of very high accuracy without side etching, by adding ion injection to lithography. CONSTITUTION:A phosphosilicate glass film 2 is coated on the surface of an Si substrate 1. A photoresist film 3 is coated on the film 2. Exposure and development are effected through a required mask to provide an opening 4 in the film 3 by patterning. The film 3 is used as a mask to inject phosphorus ions through the surface into the portion of the film 2 exposed in the opening 4. As a result, a larger amount of phosphorus is injected into the exposed portion of the film 2 than its other portion coated with the film 3 and the adhesive power of the film 3 to the other 2 is greatly heightened. Etching is then performed. Since the films 2, 3 are tightly fitted on each other, no etching solution invades in between the films. Since the exposed portion of the film 2 contains more phosphorus than its other portion, the etching speed of the exposed portion is so high that the etching of the exposed portion is completed before sides of low phosphorus content are etched.

IPC: H03J1/04
Filed: 1979-08-02
Abstract: PURPOSE:To enable round of N notation, by changing the 9-notation counter into N-notation counter, through the display of frequencies of a broadcasting station through the round of received frequency every 9-notation. CONSTITUTION:With the pulse T1 from the control signal generator 7, the preset circuit 3 presets the value of the counters 1,2 to-459 when the intermediate frequency is at 455kHz. The succeeding pulse T2 opens the gates 8-10, and the counters 1,2 count the local oscillation frequency f0. When this count value reaches a given number, e.g. all ''0'', the numeral detection circuit 5 operates the 9-notation counter 4 via the control signal generator 7. This counter 4 counts f0 in synchronizing with the counter 2. When the pulse T2 is disappeared, the counters 1,2,4 stop operation. The numeral detection circuit 6 detects the value of the counter 4 and pulse T3 is generated from the control signal 7 so that the clock CL can be counted on the counters 2,4 until this value reaches ''0''. The value on the counter 2 shows accurate broadcasting frequency every 9kHz.
