Title: Field-effect transistor and fabrication thereof
Inventor: FUJITA KOICHI
IPC: H01L21/336
Filed: 1993-04-23
Abstract: PURPOSE:To enhance the breakdown voltage between a drain and a source while suppressing the fluctuation of a threshold voltage by forming a heavily doped source impurity diffusion layer having conductivity type different from that of the substrate on the source side of a gate electrode and forming an impurity ft. diffusion layer of the same conductivity type as the substrate while covering the source impurity diffusion layer. CONSTITUTION:A gate oxide 2 is deposited by thermal oxidation, for example, on a P semiconductor substrate 1 and a gate electrode 3 is formed thereon. N type impurities, e.g. phosphorus or arsenic, are then implanted using the gate electrode 3 as a mask thus forming a source side N diffusion layer 4a and a drain side N diffusion layer 4b. Subsequently, a window is opened on the source electrode side with the gate electrode 3 as a border and a drain part coating resist mask 5 is formed while covering the drain electrode side. A heavily doped N diffusion layer 6a of phosphorus or arsenic is further formed at the source electrode part and impurities, e.g. boron, are implanted using the resist mask 5 thus forming a P type diffusion layer 7.

Title: Optical integrated circuit
Inventor: HIRUMA TAKEYUKI
IPC: G02F1/025
Filed: 1984-05-16
Abstract: PURPOSE:To improve the coupling efficiency of light guides and an optical fiber by providing a total reflecting part to the light guides on an optical integrated circuit and setting the angle between the optical fiber and the optical axis of the light guides at the input and output end faces at 0. CONSTITUTION:A p-n junction is formed to an optical path switching part. The refractive index near the energy gap of the light guide 17 exhibits large dispersion when forward bias current is passed to the electrode 4 on a substrate 1. The change-component of the refractive index is 0 at <=0.2mA forward bias current if the wavelength of the signal is selected at the wavelength corresponding to the energy gap of the light eguide 17 in this stage and therefore the light entering the light guide 10 after propagating through the light guide 2 passes through the light guide 17. On the other hand, the refractive index of the part of the light guide 17 decreases and the light is totally reflected at <=12 deg.phi when the forward bias current is increased to 48mA. Switching of the optical path is thus executed by turning on and off the forward bias current in the above-mentioned way.

Abstract: PURPOSE:To improve the use efficiency of the number of times by immediately transmitting a busy signal when reception ports in MFC signal transmission/ reception means are used at the termination time of an MFC signal from other stations and immediately making an incoming call when there is the idle port. CONSTITUTION:When one reception port in the MFC signal transmission/ reception means 1011-101n is idle when the MFC signal 104 terminates from the other station, a control means 103 uses the port and receives the MFC signal 104 by using the port. When all the reception ports in the MFC signal transmission/reception means 1011-101n are used, the control means 103 transmits the busy signal 105 from a busy signal transmission means 102 to the other station. When there is no idle port, the busy signal 105 is immediately transmitted and an originating station-side immediately discriminates the busy state of a termination station-side. When there is the idle port, the incoming call is immediately made from the originating station to a terminating station. Thus, the use efficiency of the line can be improved.

Title: Wafer supporting jig
Inventor: SUMITOMO KENJI
IPC: H01L21/22
Filed: 1979-08-01
Abstract: PURPOSE:To prevent the warpage of the wafer by supporting the upper and the lower portions of the wafer with a rodlike frame to reduce the cooling speed difference between the front surface and the back surface thereof. CONSTITUTION:The jig 8 is formed of quartz or the like of rod. The rod 4 is angularly formed on the surface to bring the wafer into line contact therewith. In this manner thermal conduction from the jig to the wafer 2 is prevented to expose the most of the back surface of the wafer with outer atmosphere.

Accordingly, the difference of the cooling speed between the front surface and the back surface of the wafer is reduced to prevent warpage of the wafer. Therefore, it can eliminate the defect to the exposing step.
