There is provided a light-emitting apparatus with favorable radiation light intensity, which is excellent in light extraction efficiency, color temperature and color rendering property. The light-emitting apparatus includes a light-emitting element, a base body having, on its top surface, a placement portion for emplacing thereon the light-emitting element, a frame body attached to the top surface of the base body so as to surround the placement portion, a light transmitting member disposed inside the frame body so as to cover the light-emitting element, and phosphors contained in the light transmitting member, which performs wavelength conversion on the light emitted from the light-emitting element. The light transmitting member has a pre-cured viscosity ranging from 0.4 to 50 Pa.s.

In manufacturing a ceramic multi-layer wiring substrate which is formed by stacking a plurality of ceramic layers and which includes an internal wiring, a ceramic paste is printed using a screen printing process on a part of a ceramic green sheet to be a ceramic layer having the internal wiring formed thereon which part does not include the internal wiring, to form between the ceramic layers a ceramic filling layer including a same ceramic component as that in the ceramic layers which ceramic filling layer is not formed on the internal wiring. The ceramic paste includes a ceramic component, an acrylic resin, and a cellulose resin, and loss factor tan δ of the paste represented by (loss modulus)/(storage modulus) in a dry condition after printing is equal to or greater than loss factor tan δ of a conductor paste layer to be the internal wiring in a dry condition.

A SiC MOSFET has a subject that resistance in the source region is increased when annealing for metal silicidation is performed to a source region before forming the gate insulating film, the metal silicide layer of the source region is oxidized by an oxidizing treatment (including oxynitriding treatment) when the gate insulating film is formed. When a metal silicide layer to be formed on the surface of a SiC epitaxial substrate is formed before forming a gate insulating film interface layer (oxide film), and an anti-oxidation film for the metal silicide is formed on the metal silicide layer, it is possible to suppress oxidation of the metal silicide layer by the oxidizing treatment upon forming the gate insulating film interface layer and the resistance of the source region can be decreased without lowering the channel mobility.

摘要:
In a computer 20 with a three-dimensional shape conversion program installed therein, a coordinate processing unit 21 obtains two-dimensional coordinate data of a contour stroke SS input through the user's operation of a mouse 50 or another suitable input unit. A 2D/3D modeling unit 22 performs two-dimensional modeling based on the obtained two-dimensional coordinate data and thereby generates two-dimensional model data regarding a two-dimensional pattern, while performing three-dimensional modeling based on the generated two-dimensional model data and generates three-dimensional model data regarding a three-dimensional shape obtained by expanding the two-dimensional pattern. A 2D model data regulator 23 adjusts the two-dimensional model data to make a corresponding contour of the three-dimensional shape defined by the three-dimensional model data substantially consistent with the input contour stroke SS.

摘要:
The present invention enables screening of the so-called variable retention time (VRT) failure, namely a retention failure occurring in a DRAM due to fluctuation of a data retention time like a random telegraph noise. A pause/refresh test for checking a data retention function is repeated at all memory cells of a chip so that memory cells at which the retention failure due to random fluctuation of the data retention capability over time may occur is subjected to screening.
