Title: Junction field-effect transistor and manufacture thereof
Inventor: TSUKINO SHINJI
IPC: H01L21/337
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To obtain a junction field-effect transistor(JFET) formed so that the diffusion depth of the impurity in a gate region does not vary. SOLUTION: The JFET 30 has the same constitution as that of the conventional JEFT, except that a protective film 32 on a GaAs substrate 12 is formed as a double layer structure. The protective film 32 has an SiN film of 20 nm thick for generating a compressive stress as a first protective film 32a and an SiO2 film of 20 nm thick for generating a tensile stress as a second protective film 32b in the form of a two-layer laminate structure. This functions to cancel the stresses mutually in diffusing an impurity by heat treating and hence the stresses in the insulation films i.e., the protective films never vary. Thus, the impurity diffusion depth variation due to the stress variation in the protective films does not occur and hence the transistor characteristics such as threshold voltage variation does not occur.

Title: Semiconductor photoelectric conversion device
Inventor: MURANO SHUNJI
IPC: B41J2/44
Filed: 1989-05-20
Abstract: PURPOSE:To obtain a photoelectric conversion device with an optical output of high density and quality by a method wherein an electrode formed on the surface of a semiconductor substrate where a semiconductor part is formed is formed into such a shape that it is large enough to cover the semiconductor part and provided with a through-hole of predetermined size. CONSTITUTION:When a current is applied between electrodes formed on both the sides of a one-way conductivity type semiconductor substrate, and light is emitted adjacent to the junction between the electrodes and a semiconductor part in the light emitting region of the semiconductor substrate. In this case, an electrode 17 formed on the surface of the semiconductor substrate where the semiconductor part is formed is formed large enough to cover the semiconductor part and provided with a through-hole 17d of predetermined size. Therefore, the emitted light is outputted only through the through-hole 17d, so that the same effect as a case in which a light emitting region is made narrow can be obtained. By this setup, when a semiconductor part is formed through a diffusion technique, a mask used for diffusion is not required to be unnecessarily improved in processing accuracy and a light emitting region of high density and quality can be obtained.

Abstract: PROBLEM TO BE SOLVED: To enable the long-term repetitive use of a crucible for producing a bismuth substd. rare earth iron garnet single crystal by providing the inner side of a platinum crucible with a corrosion preventive zone made of platinum separable from this platinum crucible to prevent the flow of melt from extending to a crucible body. SOLUTION: The inner side of the platinum crucible is provided with the corrosion preventive zone made of the platinum separable from the platinum crucible. The corrosion preventive zone made of the platinum which is smaller by about 0.3 to 20 mm in the outside diameter than the inside diameter of the platinum crucible and is about >=25 mm in the width is preferable. This zone is preferably disposed within a range of an upper part 5 mm to a lower part 20 mm than the melt surface. The role of the corrosion preventive zone is to prevent the influence of the flow of the melt by rotation of a substrate at the time of stirring or crystal growth from being exerted on the crucible body. The progression of corrosion when the production of the single crystal is repeated is around the melt surface of the corrosion preventive zone and the corrosion of the crucible body does not occur.  The corrosion preventive zone is replaced before the corrosion preventive zone is bored with a hole upon progression of the corrosion.

Abstract: PURPOSE:To prevent the effect of the waving of a liquid, by providing a wave transmitter and a wave receiver so that they are submerged in the liquid when the liquid level is higher than a specified liquid level. CONSTITUTION:An ultrasonic wave transmitter T and an ultrasonic wave receiver R are provided at position relationship in a tank (t) so that a wave transmitting front f1 does not face a wave recieving front f2.

Thus the wave can be received by the wave receiver R. When the liquid level l in the tank (t) becomes lower than the wave transmitter T or the wave receiver R, which is located at a higher position. The wave cannot be received by the wave receiver R. Therefore, whether the liquid level is located higher than a specified liquid level l or not is detected.
