Patent JP-H04330735-A (JP)
Title: Inverted stagger-type thin-film transistor and manufacture thereof
Inventor: SERA KENJI
IPC: H01L21/336
Filed: 1991-02-07
Abstract: PURPOSE:To obtain a device structure whose breakdown strength and leakage current are improved and whose difference in level is small by a method wherein a high-melting-point metal film is oxidized by using an insulating-film mask and other parts excluding a gate electrode and a part to be used as wiring are changed into a light-transmitting insulating film. CONSTITUTION:A tantalum film 201 which forms a gate electrode is formed on a glass substrate 101; a silicon oxide film 301 is formed on it and patterned to be the shape of the gate electrode. Then, the tantalum film 201 other than the part covered with the silicon oxide film 301 is oxidized and changed into a transparent insulating film (a tantalum oxide film 202). Since the silicon oxide film 301 is ultrathin and the thickness of tantalum oxide is thicker than the thickness of the tantalum film, an interconnection layer (the tantalum film 201) becomes a structure which is buried in the insulating substrate. In addition, since the oxide film creeps into the end of the silicon oxide film, the end part of a gate insulating film swells, and only the end part of a channel becomes a structure in which the thickness of the gate insulating film is increased.

IPC: B21B27/00
Filed: 1989-01-27
Abstract: PURPOSE:To improve the wear resistance in edge parts and to improve the service life over the entire part of the roll by subjecting the surface in the barrel part of the roll to Cr plating and plating the parts of the surface near the parts where the edges of a steel sheet pass to the plating hardness higher than the plating hardness in the other parts. CONSTITUTION:The relation between the surface hardness of the roll and abrasion wear of the roll 2 is such that the abrasion wear decreases with an increase in the surface hardness. The relation is thus nearly linear. A lead electrode 4 is, therefore, used to increase the hardness in the edge parts of the roll for rolling having the large wear resistance. The surface in the hatched parts of the lead electrode 4 is coated by an insulator 41 and only the parts 42 corresponding to the edge parts of the roll 2 are not covered with the insulator and are energized. The current density in the edge parts of the roll is increased in this way and the thickness of the Cr plating is increased, by which the hardness higher than the other parts is obtd. and the wear resistance is improved.
