Title: Manufacture of field effect transistor
Inventor: TONAMI YOSHIYUKI
IPC: H01L29/812
Filed: 1993-09-13
Abstract: PURPOSE:To make a distance between a source and a gate extremely small by vapor-depositing at least either source electrode or gate electrode from an upper diagonal portion of a current path by using the same mask pattern. CONSTITUTION:As shown by an arrow 4b, a gate electrode 6 coming in Schottky contact with a conductive layer 1a of a semiconductor is formed by diagonal vapor deposition from a left upper portion (above source electrode side). Both ends of the gate electrode 6 are bent at the time of diagonal vapor deposition because the height of a resist 3 at both end portions of the gate electrode 6 is higher by the height of a resist 2 than the central part. No bending occurs in the case of vertical vapor deposition. Also, a lower portion of the gate electrode 6 is extended long outside the conductive layer 1a because this is necessary for connecting feeding pads. Also, a fine gate electrode can be formed without using electron beam because the gate electrode is vapor deposited from a gap between a mask pattern and a source electrode.

Filed: 1987-09-14
Abstract: PURPOSE:To obtain a lateral PNP transistor which is strong against a surge voltage by separating the contact section of the collector electrode of a collector region from the outer periphery of the collector region as far as a specific distance or further. CONSTITUTION:In a lateral PNP transistor in which an input signal in the input stage of an integrated circuit is applied directly to its base electrode, the collector section 10a of the collector electrode 10 of a collector region 6 is isolated at least 8mum or more from the outer periphery of the region 6. For example, one P-type region 5 formed by diffusing in an N-type epitaxial layer 2 on the surface of a P<-> type substrate 1 is employed as an emitter, the other P-type region 6 is employed as a collector and the layer 2 is employed as a base, and the region 5 is formed in a structure surrounded by the collector region 6. The position of the contact section 10a of the electrode 10 is so set at a distance A as shown as to be 8mum or above. Thus, the concentration of an electric field when a surge voltage is applied to a base terminal is alleviated, and its surge resistance voltage can be enhanced.

Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To track ineffective information fast with spatial efficiency by processing a tile as a tile which is possibly ineffective only when one pixel is present in an ineffective rectangle and the tile including the pixel is flagged as ineffective one. SOLUTION: To make effective an area A in an image 10, an area B is demarcated as an intersection of the area A to be made effective and an ineffective rectangle 16. When the area B is not empty, which tile 14 crosses the area B is determined. Respective tiles 14 which cross the area B are marked and sampled as effective ones. Namely, when the area A should be made effective, the area B which is demarcated is the same as the area A. The area B is not empty, so a tile 14 crossing the area B is determined. Thus, a minimum group of pixels which should be recalculated and made effective can be determined.

Abstract: PURPOSE:To display a picture with good resolution over the whole area of the fluorescent screen by installing a generating means of an axial asymmetrical lens electric field and by generating a lens electric field which becomes a diverging type in the horizontal direction and a focusing type in the vertical direction. CONSTITUTION:Longitudinal electron beam through holes 4a-4c and long sideways electron beam through holes 5a-5c are made in the end face at a second focusing electrode side of a first focusing electrode 4 and in the end face at a first focusing electrode side of a second focusing electrode 5 respectively as a generating means of an axial asymmetrical lens electric field. As a result of an increase in a deflection angle of an electron beam, therefore, a potential difference is produced between a first auxiliary electrode 18 and a second auxiliary electrode 19 and between the second auxiliary electrode 19 and the first focusing electrode 4, respectively. The potential difference generates an axial asymmetrical lens which is a diverging type in the horizontal direction and a focusing type in the vertical direction. It is thereby possible to generate a beam spot almost in a circle over the whole area of a fluorescent screen and get a good resolution over the whole area thereof.
