Title: Hall element
Inventor: MORIKAWA HIROSHI
IPC: H01L43/06
Filed: 1984-01-23
Abstract: PURPOSE:To prevent dispersion among elements or variation by a temperature by forming a Schottky junction or a P-N junction on an input current path and applying bias voltage to the junction from the outside. CONSTITUTION:A region 1 consists of an N type single crystal layer, and a region 2 is composed of a Schottky metal forming a Schottky junction with the region 1. A region 3 represents a depletion layer by the Schottky junction, and the thickness (l) of the region 3 can be changed by reverse bias voltage V applied from the outside. Consequently, the thickness d-l of a path for input currents I can be altered by reverse bias voltage, and Hall output voltage can be controlled by voltage V. The object can be attained even when a P layer is formed in place of the Schottky metal 2 at that time.

Title: Screen printing mask
Inventor: FUKAYA RITSUO
IPC: B41C1/14
Filed: 1993-01-26
Abstract: PURPOSE:To make a design of a composite integrated circuit having a small pattern rule easy, by a method wherein such a processing is performed to the surface of a constituent member of a metal screen that lowers reflectance of light in the vicinity of a sensitizing wave zone of a photosensitive emulsion layer. CONSTITUTION:A screen material 1 which is obtained by making a fine wire of stainless steel into plain weave is coated with a photosensitive emulsion 3 of polyvinyl alcohol and an emulsion layer is held plain by a screen material 1. Although reflection preventive processing is performed to a screen 1, a light absorbing and reflection preventive film 2 is formed concretely as a reflection preventive processing. Concretely further, the reflection preventive film 2 is formed by applying polyvinyl resin having extremely low viscosity, to which dyes absorbing ultraviolet rays are added, to the screen material 1 and drying the same. At this time, it is preferable to let the reflection preventive film itself also have photosensitivity. The obtained screen printing mask reduces reflecting ultraviolet rays from the surface of the screen material 1 and a dimensional change of a mask removal pattern can be controlled.

Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To provide a thin-film transistor where adverse effects caused by the concentration of an electric field at the edge part of a semiconductor layer in an island shape can be reduced, and its manufacturing method. SOLUTION: A polysilicon layer 3 is formed in an island shape on a transparent insulation substrate, and a gate insulation film 4 is formed on the upper surface of the polysilicon layer 3.
