Title: Semiconductor device
Inventor: TSUKURIDA YASUTAMI
IPC: H01L29/84
Filed: 1984-04-04
Abstract: PURPOSE:To obtain the titled device generating transmission resonance and having negative resistance by a method wherein the thickness and depth of a well are adjusted in said device with a structure that a potential well is built in by sandwiching different semiconductor layers between semiconductor materials. CONSTITUTION:A non-doped GaSb layer 22, an InAs layer 23 serving as the potential well, a non-doped GaSb layer 24 whose electrons are accelerated, and an N<+> type GaSb layer 25 to take ohmic contact are formed by lamination on an N<+> GaSb substrate 21. Next, this lamination is shaped as required by covering a necessary region with a resin mask, and by etching it; then, an electrode 26 is mounted on the uppermost layer 25. The electrode 26 is formed also on the surface of the substrate 21 exposed around the lamination. In this construction, the thicknesses of the layers 22, 23, 24, and 25 are approx. 2,000Angstrom , 100Angstrom , 2,000Angstrom , and 2,000Angstrom , respectively; thus, the characteristic of negative resistance is generated by obtaining a potential well depth of 0.83eV.

Title: Apparatus for manufacturing semiconductor wafer
Inventor: AONUMA SHINICHIRO
IPC: H01L21/304
Filed: 1993-03-03
Abstract: PURPOSE:To prevent the contamination of a semiconductor wafer by impurities and impure gases so as to improve the yield of a highly-integrated semiconductor circuit. CONSTITUTION:The main body of the title apparatus formed of a glass-like carbon base material is coated with carbon films 2. The base material can be manufactured by heat-treating a carbonaceous material with a high- temperature halogen gas and, when the base material is heat-treated, metallic impurities contained in the carbonaceous material can be easily removed, since the impurities become chlorides. In addition, since the base material has a remarkably small number of pores, the amount of gases discharged from the base material is reduced. Moreover, since the apparatus is coated with the carbon films 2 having high hardness, no much shavings are produced. Furthermore, since the pores of the base material are closed by the film 2, the amount of discharged gases is further reduced.

Filed: 1988-03-18
Abstract: PURPOSE:To reset the potential of an output electrode and to improve charge detecting sensitivity by injecting electrons and holes into the electrode by a reset transistor connected to a bias gate electrode and the output electrode. CONSTITUTION:An N-type output diffused region 6 is formed in an element forming region adjacent to a charge transfer register 5, and an output electrode 7 having a Schottky junction is provided on the surface. A reset transistor 10 is composed of the region 6, a gate electrode 8 provided adjacent to the region 6 and an N<+> type region 9. As a signal charge is stored, the potential of the region 6 and hence the potential of the electrode 7 capacity-coupled to the region 6 is reduced, and this potential variation is externally output through an output amplifier 12. The capacities Cs of the electrode 7 and the region 6 are of the capacity of a depleted layer in the region 6 generated due to the Schottky barrier of the contact shown by C to be increased several times as large as the capacity between a floating gate electrode and the output diffused region, thereby improving several times the charge detecting sensitivity.

Title: Control apparatus for electro-magnetic apparatus having proportional solenoid
Inventor: OOKANE HIROAKI
IPC: F16K31/06
Filed: 1984-04-05
Abstract: PURPOSE:To supply a current in accordance with a command value by correscting a command signal in accordance with the operating condition of a temperature control switch of operation chamber and controlling a current supplied to a proportional solenoid by such signal. CONSTITUTION:When external temperature is high, a heating switch 19 is opened. Therefore, the signal SH becomes 0 and an output signal S0 of interface 20 becomes L. Accordingly, a switch 23 connects the terminal 23B and terminal 23C. Under this condition, when a command signal VP is input, values K2.VP (K1, K2 are correction values) are output from a gain circuit 22. In this case, the signal VP is modulated with high modulation degree and a larger current is supplied to the proportional solenoid 13, compensating for the current to be lowered. Meanwhile, external temperature is low, an operator closes the heating switch 19 to activate a heater 17. Thereby, the signal S0 becomes H, connecting the terminal 23A and terminal 23C and the values K1.VP are outputted from the circuit 22. Therefore, a low level current is supplied to the solenoid 13.
