Abstract: PURPOSE:To obtain a compound semiconductor device with good yield having stable characteristics by providing active regions with different impurity concentrations on a semiinsulating substrate surface through alignment to a sheet of photo-mask. CONSTITUTION:Windows 25a, 25b are opened in an SiO2 22 on a semiinsulated substrate GaAs with a resist mask 23 and Si ion is implanted thereto, thereby forming layers 26'a and 26'b. The mask 23 is removed, and a resist mask 28 having a window 27 which exposes the window 25b is formed. Then, Si ion is implanted again to the layer 27'b. Thereby, the layer 29' of which concentration is about two times of the layer 26'a is formed. The resist 28 and SiO2 22 are removed and the surface is covered with a protection film and then activated. This protection film is removed and the source electrode 30 and drain electrode 31 of the AuGe/Au are formed as specified on the N layer 26, while the electrode 32 on the N layer 29 through alignment with a sheet of photo-mask, and the Schottky electrodes 33, 34 of Ti/Pt/Au on the layers 26, 29 respectively through alignment thereto. Thereby, an FETSBD element having different performance can be completed. According to this structure, the characteristics are constant and yield is also good.

Patent JP-H0456867-A (JP)
Title: Toner
Inventor: HORIKOSHI YUZO
IPC: G03G9/087
Filed: 1990-06-22
Abstract: PURPOSE:To contrive the improvements in a void resistance characteristic by specifying the surface tension of an applied binder resin. CONSTITUTION:In a toner using the binder resin, the surface tension of the binder resin is <=15dyne/cm at 200 deg.C. To prevent the degradation of a fixing property due to the raise of the meting point of the binder resin, or the degradation of an antiblocking property due to the drop of the glass transition temp., even in case that the binder resin of a relatively lower melt viscosity is used, a substance to weaken at least the surface tension or the intermolecular force acting between the molecules constituting the binder resin, that is a surface tension reducer, is dispersed in the toner and the toner reduced the surface tension is used. Thus a void resistance characteristic is improved.

Title: Ink sheet cassette and recording apparatus using the same
Inventor: MUNEISHI HIROSHI
IPC: B41J32/00
Filed: 1989-06-29
Abstract: PURPOSE:To use an ink sheet two or more times by changing a mounting direction even when the front and rear of an ink sheet cassette are not reversed by respectively providing drawing-out parts for drawing out the ink sheet to one peripheral wall and other opposite peripheral wall of the housing constituting the ink sheet cassette to provide two mounting directions. CONSTITUTION:When a current is supplied to a recording head 12 corresponding to an image signal in synchronous relation to the running of a carriage 7 in a direction (d), the heating element 12a of the current supplied part generates heat and the thermal transfer ink of the ink sheet 3a passing through a recessed part 1c is melted to be transferred to a recording sheet 14 to perform recording. When the ink sheet 2 is exhausted on the side of the core 3a and entirely taken up by a core 3b, an ink sheet cassette A is once detached from the carriage 7. The ink sheet cassette A is rotated by 180 deg. so as to be reversed before and behind and re-mounted on the carriage 7 so that a recessed part 1d is positioned at the part of the recording head 12. By this method, the core 3b becomes a supply core and the core 3a becomes a taking-up core and thermal transfer recording is performed.

Title: Method and equipment for inspecting semiconductor device
Inventor: TANAKA MAKI
IPC: G01N23/225
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To provide an inspecting method using a scanning electron microscope and an equipment for it with which an electron beam which is stable extending over a long time is obtained for a sample without being affected by charging-up. SOLUTION: Charging-up is controlled by irradiating the surface of a sample wafer with an electron shower and an ion shower. Charging-up is controlled with a controlling calculator 20 according to an inspection condition and a material quality of the sample, etc. A stable electron beam image wherein a condition of charging-up does not charge is inputted with a secondary electron detector 15, and then compared/inspected at a picture processing part 19, to detect a defect of a semiconductor device. By this, an influence on the electron bean image due to charging-up of the surface of the sample is avoided, and a stable inspection extending over a long time is realized with the electron beam image. Further, by feeding an inspection result back to a semiconductor manufacturing process, a defective coefficient of the semiconductor device is reduced, and reliability is improved.
