Patent number: 7009847Abstract: A connector concealment mechanism for computer peripheral device is proposed, which is designed for use in conjunction with a computer peripheral device equipped with an external connector for the connector to be concealable into the casing of the computer peripheral device when not in use, and be easily ejected out of the computer casing for use to connect the computer peripheral device to a computer unit. This feature allows the computer peripheral device to be more advantageous to use than the prior art due to the fact that it allows the user to conceal the connector into the casing of the computer peripheral device when not in use, without having using a separable cap which would easily get lost as in the case of the prior art, thus making the use of the computer peripheral device more convenient and trouble-free than prior art.Type: GrantFiled: December 20, 2004Date of Patent: March 7, 2006Assignee: Inventec Multimedia & Telecom CorporationInventors: Kuo-Chang Wu, Yi-Min Tseng, Hsin-Chiang Ho, Ya-Chyi Chou, Kao-Yu Hsu

Patent number: 6307273Abstract: An improved alignment mark used by a laser trimming tool to locate fuses in an underlying integrated circuit is formed using conventional processing sequences. The design features high resolution and improved low noise characteristics. The alignment mark is etched in a shallow layer over a metal layer rather than in the metal itself. The edges which are sensed by the scanning alignment laser of the trimming tool have their elevated portions external to the alignment mark. The improved design replaces a prior art design in which the metal mark protruded from a deep area in the site region. Debris in deep areas adjacent to alignment marks etched in metal, is avoided by the improved design. The absence of this debris virtually eliminates noise in the alignment scan thereby greatly reducing alignment errors.Type: GrantFiled: June 7, 1996Date of Patent: October 23, 2001Assignee: Vanguard International Semiconductor CorporationInventors: Rong-Wu Chien, Kuo-Chang Wu

Patent number: 6008137Abstract: A plasma etch method for forming a patterned silicon nitride layer within an integrated circuit. There is first provided a substrate having formed thereover a blanket silicon nitride layer. There is then formed upon the blanket silicon nitride layer a patterned photoresist layer. Finally, there is etched through a plasma etch method while employing the patterned photoresist layer as an etch mask layer the blanket silicon nitride layer to form a patterned silicon nitride layer.

Patent number: 5899747Abstract: A method for forming a gate with a tapered spacer is disclosed. The method includes forming a polysilicon layer on a substrate, and then forming a first oxide layer on the polysilicon layer. A photoresist layer is formed on the first oxide layer, where the photoresist layer defines a gate region, and then portions of the oxide layer and the polysilicon layer are removed using the photoresist layer as a mask, thereby forming a gate. A second oxide layer is formed on the substrate and the first oxide layer. Afterwards, the second oxide layer is isotropically etched so that the slope of the second oxide layer near the upper corners of the gate is reduced. Finally, the second oxide layer is anisotropically etched back to form spacers on the sidewalls of the gate.Type: GrantFiled: January 27, 1997Date of Patent: May 4, 1999Assignee: Vanguard International Semiconductor CorporationInventors: Kuo-Chang Wu, Tzu-Shih Yen
