Title: Semiconductor device
Inventor: GOTO MAKIO
IPC: H01L21/76
Filed: 1988-03-22
Abstract: PURPOSE:To obtain a semiconductor device which is economical, formed easily to have a large diameter and operated with a high speed by burying GaAs in a part of an Si substrate. CONSTITUTION:A trench is formed by etching the surface of a P-type Si substrate 101 and an SiO2 film is formed over the whole surface by thermal oxidation. Then polycrystalline GaAs is applied to the SiO2 film and subjected to a thermal treatment to build up a single crystal of GaAs. After that, the GaAs single crystal and the SiO2 film are removed by etching except the parts in the trench to form an SiO2 film 102 and the single crystal GaAs 103. With this constitution, a GaAs-Si hybrid IC is produced and merits such as a large diameter and a low cost can be provided by employing Si as the substrate material and the high speed processing of a signal can be realized easily by the existence of GaAs.

Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To easily detect gas leakage, even when this equipment is provided with an additionally installed tank whose inside temperature in a state of operating is different from that of an equipment body. SOLUTION: When gas leakage occurs in either an equipment main body 3 or a pushing pocket 6, a pressure in the equipment main body 3 and the pushing pocket 6 is decreased due to the gas leakage, and a pressure to be added to a first bellows 10 is decreased according to this, and when a second bellows 12 is moved, a switch 18 is closed, and gas leakage can be surely detected. As a result, even when this equipment is provided with the equipment body 3 and the pushing pocket 6 in which temperature difference with this is generated, it is not necessary to decrease a detection gas pressure as in the conventional technique, and the gas leakage can be detected easily. Also the gas leakage can be surely detected, without individually setting a detecting device, and the increase of the number of parts or mounting work man-hours or cost-up can be suppressed.

Title: Charged-beam exposure device
Inventor: ANDO KOJI
IPC: G03F7/20
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To increase a charge in a molding deflector by a method wherein the deflector for deflecting a charged beam is driven so that the absolute value of a voltage, which is applied between electrodes on the right and left sides of the deflector by the deflector, is reduced lower than a preliminarily voltage value. SOLUTION: When a bias voltage is appliecd to a molding deflector 5, an electron beam 4 is deflected to the left side. At this time, a constant bias voltage is applied between electrodes on the right and left sides of the deflector 5 to bind a low-energy electron 26 in the vicinity of the electrode on the left side and a charge in one surface of the electrode is increased 27 to saturate steadily the voltage. Moreover, even if the position of deflection of the beam 4 is changed, the low-energy electron is never released as it is bound in the vicinity of the left side electrode and even if the voltage to deflect the beam 4 is changed in the state leaving as the charge in the surface of the electrode is increased 27, a state that the low-energy electron is not moved in the deflector 5 is obtained. Therefore, an offset drift is not generated, the actual beam can be set accurately to a set beam and even if a dummy drawing is not performed, the drawing accuracy of a charged-beam exposure device can be enhanced.
