20080231643Method and apparatus for controlling the size or opacity of map elements rendered in an interactive map view - To provide the illusion of smooth motion during zoom or pan operations of an interactive map display, relatively unimportant map elements are not rendered during map movements. By reducing the number of elements to be rendered in each frame during the movement, a map display rendering engine can increase its frame rate, thus providing the illusion of smooth motion. At the completion of the zoom or pan operation, the omitted elements “fade in” by successively rendering the same frame with the omitted elements' opacity gradually increasing in each frame. The selection of map elements to omit during map movement is made by comparing a dynamic value stored with each layer of map elements to a rendering performance value, which may be based on the computational power of the rendering engine, and may be set upon installation of the map software.09-25-2008

20120115297METHOD FOR FABRICATING A TUNNELING FIELD-EFFECT TRANSISTOR - The present invention discloses a method for self-alignedly fabricating tunneling field-effect transistor (TFET) based on planar process, thereby lowering requirements on a photolithography process for fabricating the planar TFET. In the method, the source region and the drain region of the TFET are not directly defined by photolithography; rather, they are defined by another dielectric film which locates over an active region and on both sides of the gate and which is different from the dielectric film that defines the channel region. The influence due to the alignment deviation among three times of photolithography process for defining the channel region, the source and the drain regions may be eliminated by selectively removing the dielectric film over the source and drain regions by wet etching. Therefore, a planar TFET may be fabricated self-alignedly based on this process, thereby the rigid requirements on the alignment deviation of the photolithography during the fabrication procedure of a planar TFET is alleviated, which facilitates to fabricate a planar TFET device with stable and reliable characteristics.05-10-2012
