摘要:
When a semiconductor sensor element used for detecting high-energy x-rays and gamma rays and an amplifier are connected via wires, the capacitances vary depending on the wires, thereby causing a sensitivity variation. To solve this, a structure for making the capacitances uniform is proposed. If a staggered arrangement is used for high resolution, the capacitances by wiring are different from element to element, so dummy sensor mounting sections (2) are provided to electrode sections (3) to make the capacitance uniform. The width of the connection section is decreased depending on the wiring length so as to make the capacitance uniform.

Disclosed is a photoelectric conversion device having a multiplying function and an image sensing device using the same. The photoelectric conversion device essentially comprises three layered structure: a carrier generation/multiplication layer composed of amorphous silicon to have both the function of absorbing light and generating carriers through optical excitation and the function of multiplying the generated carriers; an electron injection inhibiting layer composed of an amorphous silicon carbide of the p-type conductivity to inhibit injection of electrons into the carrier generation/multiplication layer; and a hole injection inhibiting layer composed of an amorphous silicon nitride of the n-type conductivity to inhibit injection of holes into the carrier generation/multiplication layer. The said carrier generation/multiplication layer is provided between said electron injection inhibiting layer and said hole injection inhibiting layer.

This invention provides a composite having a hydrophilic film made of amorphous titanium oxide. A film is deposited on a substrate made of, for example, glass or synthetic resin. The film is composed of amorphous titanium oxide partially having structures in which a network of Ti—O—Ti bond is broken to give Ti—OH bond terminals.

The invention provides a semiconductor light emitting device whose operating voltage can be easily reduced, a method of producing the same, and an optical device. An n-type clad layer, a first guide layer, an active layer, a second guide layer, a p-type clad layer, a first semiconductor layer, and a second semiconductor layer of ZnSe are successively grown on an n-type substrate. An alkali compound layer of Na2Se is then formed thereon. Subsequently, a heat treatment is performed by means of irradiation of an excimer laser beam so that at least a part of the second semiconductor layer and at least a part of the alkali compound layer are altered thereby forming a contact layer. Furthermore, a p-side electrode is formed on the contact layer. The contact layer contains an alkali metal serving as a p-type impurity so that the contact layer has a low electric resistance thereby achieving a reduction in the operating voltage and thus a reduction in the operating power. As a result of the reduction in the operating power, the device life is improved.

A high quality transparent SiC thin film can be deposited on the surface of a plastic material at low temperature utilizing Electron Cyclotron Resonance (ECR) Plasma CVD techniques, thereby enhancing surfacial hardness without spoiling designability. A magnetic field is applied to a plasma generating chamber by means of a surrounding magnetic coil. Microwaves are then introduced into the plasma generating chamber. Further, an upstream gas is introduced into the plasma generating chamber. ECR plasma is thus generated. A downstream gas is then supplied to the chamber from an inlet. Furthermore, the ECR plasma is passed through a mesh placed between the inlet and a polymer base material or between the plasma generating chamber and the inlet. Accordingly, a SiC film is deposited on a surface of a polymer base material.

A method of forming a uniform-thickness good-quality protective film with scratch-proofness and ultraviolet cutting characteristic on a plastic part having a diversified and complex three-dimensional shape without wasteful release of an organic solvent, or the like, into the atmosphere. In a plasma chemical vapor deposition apparatus, the shape of at least one part of a surface of a cathode provided in a reaction chamber is made coincident with the shape of a surface of a plastic part such as a car headlamp lens, or the like. The plastic part is attached to the cathode in the condition that the two surfaces coincident in shape come into contact with each other. High-frequency electric power is supplied between the cathode and the reaction chamber while a hydrogen gas and hexamethyldisilane (HMDS) as a raw material gas for forming a protective film are imported into the reaction chamber. Thus, a protective film is formed on the surface of the plastic part by vapor deposition.
