Wuxi DrientSemi-ConductorMaterials Factory. 无锡东方半导体器材厂。 2. These USES are based on the fact that silicon issemi-conductorof electricity. 这些用途基于这一事实,即硅是电的半导体。 3. The sound of valves is inherently superior to that of any kind ofsemi-conductor. ...
Any of various solid substances, such as silicon or germanium, that conduct electricity more easily than insulators but less easily than conductors. Semiconductors are able to do this because they have a small number of electrons that have escaped from the bonds between the atoms, leaving open sp...
About: Semiconductors are materials which have a conductivity between conductors and insulators. They can be pure elements, silicon or germanium or compounds, gallium, arsenide or cadmium selenide. Significance of Semiconductor Chips: They are the basic building blocks that serve as the heart and brai...

form a flat continuous surface, and forming over the continuous surface a pattern of mutually insulated conductors 48 insulated from the surface by an intervening insulating layer 30 except at apertures through this layer where the conductors make contact with regions of the semi-conductor elements. ...
PROCESS AND INSTALLATION FOR DETERMINING THE THICKNESS OF LAYERS IN LAYERED SEMI-CONDUCTORS In the process described, a semiconductor sample (4) carrying the layer configuration is tested brought into contact with an electrolyte (2) and then subjected to anodic etching, and in the attack, the inte...
These materials are black and behave as metals; but it is not completely certain whether they would be lowenergy-gap semi-conductors if they were perfectly stoichiometric. It may be worth noting that the phenomenological criterion for a metallic sample is that its electric conductivity decreases or...

For next-generation power electronics, BASF has developed a polyphthalamide (PPA) that is especially suited for manufacturing housings of IGBT (insulated-gate bipolar transistor) semi-conductors. Ultramid® Advanced N3U41 G6 addresses the growing deman
Cements are oxidic materials and, as inorganic and non-metallic building materials, possess combinations of properties that are advantageous for encapsulating semi-conductors, namely high electrical insulation (20-100 kV/mm), relatively good thermal conductivity (1-2 W/mK), and low thermal expansion...
