Title: Semiconductor device
Inventor: SATO KAZUO
IPC: H01L29/732
Filed: 1986-01-28
Abstract: PURPOSE:To improve element characteristics and to effect a reduction in the size of a semiconductor device by forming a second high density region in a first high density region, and leading a collector electrode from the portion of the same second high density region having high density. CONSTITUTION:An N-type low density semiconductor layer 22 is formed on a semiconductor layer 20. An N-type first high density region 23 connected with an N<+> type buried layer 21 is extended from the layer 22. A high density impurity region 25 which becomes an N<+> type emitter is formed in an impurity region 24. A second high density region 26 having higher density than the region 23 is extended into the region 23. Since the region 23 is formed by a molecular beam epitaxial method in this semiconductor device 35, it can prevent a crystal defect and an impurity scattering from occurring in case of forming the region 23 to form a transistor having excellent element characteristics.

Abstract: PURPOSE: To prevent a single layer ITO film constituting a picture element electrode or a source signal line from being cut and to improve the crystallization of an electrically conductive layer and to increase ON currents by respectively forming a source electrode and a drain electrode in 2-layer structures each constituted of a lower side microcrystalline n<+> silicon layer and an upper side amorphous n<+> silicon layer in pixel TFT. CONSTITUTION: A source electrode 101a and a drain electrode 101b as bases for a TTO thin film are constructed by microcrystalline n<+> silicon layers having 2-layer structures of lower side microcystalline n<+> silicon layers 15 and upper side amorphous n<+> silicon layers 25. Thus, having a flat surface, the crystalline structure of ITO is good on the source and drain electrodes 101a and 101b and the cross-sectional defects of a source signal line and a picture element electrode are limited in the source and drain electrode sections of TFT 101. Further, since the source and drain electrodes 101a and l01b are constructed by the n<+> silicon layers containing the microcrystalline silicon layers 15, ON currents for TFT 101 are increased.

Filed: 1982-02-03
Abstract: PURPOSE:To prevent the generation of hot spots and to stabilize operations by rotating and stirring the molten metal supplied into a casting mold around a core with an electromagnetic stirrer, and inclining the molten metal around the core. CONSTITUTION:Molten metal 4 is supplied continuously into the cavity between  a core 3 and a master mold 1.
