Patent number: 7741167Abstract: By forming a substantially continuous and uniform semiconductor alloy in one active region while patterning the semiconductor alloy in a second active region so as to provide a base semiconductor material in a central portion thereof, different types of strain may be induced, while, after providing a corresponding cover layer of the base semiconductor material, well-established process techniques for forming the gate dielectric may be used. In some illustrative embodiments, a substantially self-aligned process is provided in which the gate electrode may be formed on the basis of layer, which has also been used for defining the central portion of the base semiconductor material of one of the active regions. Hence, by using a single semiconductor alloy, the performance of transistors of different conductivity types may be individually enhanced.Type: GrantFiled: May 15, 2007Date of Patent: June 22, 2010Assignee: Advanced Micro Devices, Inc.Inventors: Sven Beyer, Manfred Horstmann, Patrick Press, Wolfgang Buchholtz

Publication number: 20100141666Abstract: A method and apparatus for sorting data into spatial bins or buckets using a graphics processing unit (GPU). The method takes unsorted point data as input and scatters the points, in sorted order, into a set of bins. This key operation enables construction of a spatial data structure that is useful for applications such as particle simulation or collision detection. The disclosed method achieves better performance scaling than previous methods by exploiting geometry shaders to progressively trim the size of a working set. The method also leverages predicated rendering functionality to allow early termination without CPU/GPU synchronization. Furthermore, unlike previous techniques, the method can guarantee sorted output without requiring sorted input. This allows the method to be used to implement a form of bucket sort using the GPU.Type: ApplicationFiled: July 10, 2009Publication date: June 10, 2010Applicant: Advanced Micro Devices, Inc.Inventors: Oat Christopher, Shopf Jeremy, Joshua D.
