IPC: H01L29/74
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To improve withstand voltage characteristics and reliability, by limiting conductive regions on the main surfaces by using an insulating protective film. SOLUTION: Conductive regions on the main surfaces 101, 102 are limited by using an insulating protective film 51, and a current in the peripheral part of a semiconductor substrate is controlled.

Thereby treatment is enabled without exposing electrode metal to treatment solution, and metal ions of the electrode are not dissolved in the treatment solution, so that metal ions are prevented form attaching on the side surface. In the part exposed from the jigs, the protective films 51, 52 are present on the two main surfaces 101, 102, so that reaction is not generated and only the end portion side surface 103 can be treated. Thereby treatment is enabled while keeping the form of the end portion.

Title: Chemical vapor growth device
Inventor: KISHIBE KENJI
IPC: C23C16/44
Filed: 1989-07-18
Abstract: PURPOSE:To prevent the sticking of powdery thin film materials onto the surface of a semiconductor wafer and the deterioration of the material quality of a thin film by supplying gaseous raw materials from below the wafer and passing liquid, such as water, under the wafer at the time of formation of the thin film by a CVD method on the wafer surface. CONSTITUTION:An adapter 12 is provided in a part of a pipe 11 and a wafer stage 15 mounted with the semiconductor wafer 16 is mounted on one surface of a heater 14. The stage is constituted freely movably downward and upward in directions B, C by a lifting mechanism 13. While the water 17 is passed in the direction A in the pipe 11, a gaseous mixture 19 composed of SiH4 and O2 as the gaseous raw materials is released from many small holes 21 of a gas dispersion head 18 provided in the pipe 11 into the water flow 17. The gaseous mixture rises in the form of bubbles 28 in the water and enters the inside of a reaction chamber 20 along a slope 27 and the thin film of SiO2 is formed by the reaction of the SiH4 and the O2 on the surface of the wafer 16 heated by the heater 14. The granules of the SiO2 formed in the space of the reaction chamber fall into the water 17 and are ejected together with the water to the outside. The falling and sticking of the granules to the wafer surface do not arise and, therefore, the degradation in the material quality of the thin film of the SiO2 on the wafer surface is obviated.

Title: Hydraulic damping type engine mount
Inventor: FUORUKAA HERUTERU
IPC: F16F13/00
Filed: 1991-07-01
Abstract: PURPOSE: To perform the secure decoupling of the high frequency vibration even in the case where the pressure inside of a working chamber is high by providing a working chamber and a compensation chamber connected to each other through an overflowing groove and filled with the liquid and a film provided adjacent to the working chamber so that the electrodynamic vibration of the film is generated in relation to the predetermined operation parameter. CONSTITUTION: A film 18 is formed of a rigid plate, and a back side thereof is connected to an exciting body 17 made of the piezoelectric material. This exciting body 17 itself is a rigid member and not compressed even in the case where the high pressure is generated in a working chamber 1, and position of the film plate 18 is regulated by the only arrangement of the exciting body 17. When the exciting body 17 is excited, the film plate 18 follows the shrinkage and the expansion of the exciting body 17, but the film plate 18 does not move large in response to the vibration of the exciting body 17. Since the high frequency vibration inside of an engine mount generally has an amplitude at about 0.1 mm, movement of the film plate 18 with a small stroke generated independently of a large pressure fluctuation inside of the working chamber 1 is enough to perfectly or partially eliminate the high frequency pressure fluctuation at a small amplitude overlapped with the low frequency pressure fluctuation.

For example, a driving reference voltage VR0 is outputted as an initial value to the driver output O first and then a driving reference voltage VR3 is applied to the liquid crystal. The switches SW2 and SW4 are turned ON by holding control signals A and B at high level. At the same time, the operational amplifier OIP1 is put in operation with operation control signals Z and Z of the operational amplifier OP1. Consequently, a load capacitor CL is charged speedily through the amplifying operation of a differential amplifier OP1 and the driver output O speedily reaches the driving reference voltage VR3.

Title: Method and apparatus for surface processing
Inventor: ONO TETSUO
IPC: H01L21/302
Filed: 1990-07-18
Abstract: PURPOSE:To enhance the efficiency of a processing operation by a method wherein, at a surface processing method to process the surface of a solid by using a thermally excited molecular beam, an oxide film on the surface of the solid is removed before the processing operation. CONSTITUTION:When Si is left as it is at room temperature, a spontaneous oxide film as SiO2 is formed on the surface. The speed at which SiO2 is etched by thermally excited Cl2 is at 1/1000 or lower of that for Si and SiO2 is hardly shaved. As a result, even very thin and partial SiO2 largely prevents Si from being etched. Before executing a treatment using a gas 1 for Si processing use, a gas 7 for SiO2 removal use is made to flow. The gas 7 is, e.g. HF or a mixed gas of HF with N2 When the gas 7 is made to flow, SiO2 on the surface of Si is removed; an etching operation which is executed in succession by using the gas 1 progresses without any trouble. The gas 7 may be introduced from a nozzle 2. In this case, the gas 7 used to remove SiO2 is made to flow to the nozzle in advance, and the gas 2 used to etch Si is then made to flow.
