Title: Semiconductor processing equipment
Inventor: ONUMA MASAHIKO
IPC: H01L21/205
Filed: 1990-08-08
Abstract: PURPOSE:To improve uniformity in characteristics of a semiconductor device between semiconductor substrates and in planes by providing a gas supply pipe with two or more of chambers to accumulate reaction gas and carrier gas and a plurality of supply ports which consider pressure loss. CONSTITUTION:Reaction gas and carrier gas flow in a film deposition system from above in the diagram to deposit an insulating film on a semiconductor substrate. Since the reaction gas and the carrier gas are supplied directly from the side face of a reaction tube body 6 at this time, temperatures of the reaction gas and the carrier gas are not sufficient in the reaction tube body 6 and flow rates and pressures are not uniform. However, providing a gas supply pipe 1 with two or more of chambers 2, 5 to accumulate reaction gas and carrier gas and supply ports 3, 4 with areas which consider pressure loss allows respective substrates placed in the reaction tube body 6 to uniformly contact reaction gas and carrier gas of sufficient temperatures with the result that films of uniform thickness are deposited on semiconductor substrates.

Title: Digital programmable phase shifter
Inventor: NAGAO KATSUYUKI
IPC: H03H17/08
Filed: 1982-11-30
Abstract: PURPOSE:To obtain a digital programmable phase shifter controlling the phase with high accuracy by adopting a small-sized circuit constitution comprising a flip-flop, a monostable multivibrator and a 1/n frequency-divider and the like. CONSTITUTION:When a clock having a 6,34MHz of frequency is inputted to the FF10, the clock is frequency-divided into 1/2, and pulses X, Y having 293n s of period and 180 deg. of phase difference are generated from outputs Q, Q' of the FF10. In inputting the clock pulses X, Y to monostable multivibrators 11, 11', pulses Xp, Yp having 75n s of pulse width are generated at the trailing of the pulses X, Y from an output Q. When the (n) is e.g., 1,000 the phase euqal to 1/ 1,000 of the output pulse width is made led or lagged by deleting one pulse Xp or inserting one pulse Yp from/to the output of the 1/n frequency divider 19. The more frequency dividing ratio is increased, the more minutely the phase is controlled. Thus, the phase is controlled with high accuracy by having only to increase the (n) of the 1/n frequency divider 19.

Title: Differential amplification circuit
Inventor: KITAMURA MITSUO
IPC: H03F3/45
Filed: 1988-08-26
Abstract: PURPOSE:To obtain a signal as large as possible in amplitude even for the same supply voltage by removing the emitter resistance of other side transistor(Tr), applying a prescribed bias voltage to the base potential of both Trs, and generating the output voltage of the maximum amplitude without distortion. CONSTITUTION:The emitter resistance of a TrQ2 is removed, turned to a TrQ1 side, made into a resistance RE, and thus, the base potential of the TrQ2 can be approached to a supply voltage VEE side. Consequently, the collector amplitude of the TrQ2 can be largely obtained. At this time, when a collector amplitude Vc2' is made into a gain G=1, an expression I is obtained. A VBB2 is the voltage between the base emitters of the TrQ2. On the contrary, the collector amplitude when the emitter resistance of the TrQ2 is not removed goes to an expression II. From both expressions, Vout-pp' has the output amplitude of 1.5 times as much as the Vout-pp. When the gain is >=1, the Vin is made into a smaller one, the Vout is the same, and therefore, under the constant power source voltage, a larger amplitude can be obtained.
