Title: Detecting circuit of phase difference
Inventor: AOKI KAZUO
IPC: H03L7/085
Filed: 1983-05-12
Abstract: PURPOSE:To supply the voltage having an amplitude corresponding to the ratio of phase deviation between a reference signal and an input signal, by using a frequency converter which converts the reference signal into an integer multiple as much as the frequency of the input signal. CONSTITUTION:In case an input signal is set at 4kHz and the detected phase deviation step is set twice, a reference signal 11 of 60kHz applied to an input terminal 1 undergoes the 12-multiplication through a frequency converter 2 and is converted into a signal of 720kHz. This signal is multiplied by a gate circuit 4 together with an input signal 13 applied to the circuit 4 through an input terminal 3. Then a converted pulse is convoluted into 1/2 pulse width of the input signal to obtain a signal 14. While the reference signal supplied from the terminal 1 is applied also to a frequency converter 5 to undergo 15 divisions and converted into a reference signal 15 of 4kHz. The pulse signal produced in response to the phase deviation between the signals 11 and 13 is applied to a counter 7. Then the voltage having an amplitude proportional to the number of applied pulses is delivered from an output terminal 9 of a D/A converter 8.

Title: Manufacture of semiconductor element
Inventor: HAYAMA HIROSHI
IPC: H01L21/285
Filed: 1982-05-18
Abstract: PURPOSE:To reduce the parasitic capacity by approx. one figure by decreasing the superposition between a gate and a source-drain and thus form an insulation gate field effect transistor of high performance by a method wherein the source- drain is formed in self-alignment, after a ring formed mask part is formed in the periphery of the gate. CONSTITUTION:When the part except for the side surface of the gate 2 is covered with an insulator, the speed of metal deposition becomes remarkably higher than on insulation on a conductor, therefore the ring formed mask part 6 by a metal such as aluminum and tungsten can be easily formed in the periphery of the gate, thereafter the source-drain 4 is formed in self-alignment, and thus the superposition 5 between the source-drain 4 and the gate 2 can be reduced. Besides, it is possible that the transistor of a structure without the superposition between the gate and the source-drain is formed, if the thickness 7 in transverse direction is taken large.

Title: Electrolytical etching of multilayer film
Inventor: SATO KAZUAKI
IPC: H05K3/07
Filed: 1988-04-04
Abstract: PURPOSE:To improve the reliability of a step of etching a multilayer by setting hydroxide alkali and lauryl sodium sulfate in an electrolytic bath composition to a specific concentration, and setting the specification of an electrolytic step to a specific voltage and etching rate. CONSTITUTION:The concentration of hydroxide alkaline solution is 0.35-2mole/l, and lauryl sodium sulfate concentration is 0.05-0.5g/l. A plate voltage of electro lytic condition is 1.8-2.5V, and its etching rate is set to approximately 1500 Angstroms/min. When a first chromium layer 1, a second chromium layer 2 and its base metal layer 2 are etched, oxygen is concentrated on the surface of the chromium by electrolysis, the chromium is oxidized to become CrO3 to be dissolved in solution. When the chromium is etched to expose the Cu of the base metal layer, Cu2O is generated. Since the applied voltage of the Cu2O is of a decomposing voltage or higher, it is dissolved in water to cover the base metal layer 5. Since it is covered with Cu2O generated next, the etching speed of the layer 5 becomes equal to those of the chromium layers 2, 1 so that the resist 10 is not peeled or not eroded, the etching face of an ideal shape is obtained.

Title: Vacuum pump and its evacuation method
Inventor: SHINOZUKA SHUHEI
IPC: F04B37/02
Filed: 1994-03-29
Abstract: PURPOSE:To provide a vacuum pump performing an evacuation process up to an ultra-high vacuum zone by irradiating an ultraviolet ray to vacuum space, and shifting the excited and ionized gas molecules of the vacuum space toward an evacuation direction. CONSTITUTION:This ultra-high vacuum pump, when reaching ultimate vacuum as a pump performance limit, has the approximately equal number of gas molecules flowing from the side of the pump to a vacuum vessel and vice versa, and reaches equilibrium state. In this state, an ultraviolet ray is irradiated to the gas molecules floating in vacuum space. As a result, the molecules are excited, release electrons (e<->) and turn into positive (+) ions. Among the positively ionized gas molecules, the molecules colliding with the vanes of a turbo molecular pump having negative polarity are entrapped with the vanes and discharged outside. According to this construction, the gas molecules even at the ultimate vacuum of an ordinary turbo molecular pump do not return to the vacuum vessel, and are further discharged outside. Thus, ultra-high vacuum in the vacuum vessel can be further increased by one step.
