  • Patent number: 7898049
    Abstract: A structure and method for increasing the sensitivity of pixel sensors by eliminating a gap space formed between adjacent microlens structures in a pixel sensor array. Advantageously, exposure and flowing conditions are such that adjacent microlens structures touch (are webbed) at a horizontal cross-section, yet have a round lens shape in all directions. Particularly, exposure and flowing conditions are such that each touching microlens structure is formed to have a matched uniform radius of curvature at a horizontal cross-section and at a 45 degree cross-sections. To improve quality of mircrolens structure uniformity exhibited at all pixel locations including those near a pixel array edge or corner, a top anti-reflective coating layer is applied on top of a photoresist layer prior to the exposure and flowing steps.

  • Patent number: 6812075
    Abstract: A vertically oriented FET having a self-aligned dog-bone structure as well as a method for fabricating the same are provided. Specifically, the vertically oriented FET includes a channel region, a source region and a drain region. The channel region has a first horizontal width and the source and drain regions having a second horizontal width that is greater than the first horizontal width. Each of the source and drain regions have tapered portions abutting the channel region with a horizontal width that varies in a substantially linear manner from the first horizontal width to the second horizontal width.
