Publication number: 20080053575Abstract: The present invention relates generally to a shape memory and/or super-elastic material, such as a nickel titanium alloy. Additionally or alternatively, the present invention relates to a super-elastic or pseudo-elastic material that has an initial transition temperature Af above a body temperature. The shape memory material can have a super-elasticity or pseudo-elasticity property at a temperature below the initial transition temperature Af of the material. For example, the shape memory material can have its workable temperature for producing super-elasticity or pseudo-elasticity of about 0° C. to 15° C. below the initial transition temperature Af. The shape memory material can be malleable at a room temperature, and become super-elastic or pseudo-elastic at a body temperature. In addition, the present invention relates to a method of making a shape memory or a super-elastic material.Type: ApplicationFiled: October 30, 2007Publication date: March 6, 2008Applicant: Versitech LimitedInventors: Kenneth Man Chee Cheung, Kelvin Yeung, William Lu, Chi Chung

Patent number: 6190999Abstract: A method for fabricating a shallow trench isolation (STI) structure includes a pad oxide layer and a hard masking layer are sequentially formed over a semiconductor substrate. A trench is formed in the substrate by patterning over the substrate. Then, the hard masking layer is removed to expose the pad oxide layer. An insulating layer is formed over the substrate to fill the trench. Using the pad oxide layer as a polishing stop, a CMP process is performed to polish the insulating layer until the pad oxide layer is exposed. The remained pad oxide within the trench is simultaneously planarized to have a planar top surface without dishing and microscratch. After the pad oxide is removed, the STI structure is accomplished.Type: GrantFiled: September 14, 1998Date of Patent: February 20, 2001Assignee: United Semiconductor Corp.Inventors: Tsung-Yuan Hung, William Lu
