In a method for manufacturing a semiconductor device, a semiconductor film formed over an insulator is doped with an impurity element to a depth less than the thickness of the semiconductor film, thereby forming an impurity doped layer; a metal silicide layer is formed on the impurity doped layer; the metal silicide layer and the semiconductor film are etched to form a recessed portion; and a layer which is not doped with the impurity element and is located at the bottom of the recessed portion of the semiconductor film is thinned to make a channel formation region. Further, a gate electrode is formed in the recessed portion over the thinned non impurity doped layer, with an insulating film interposed therebetween.

Described herein are systems and methods that reduce power consumption for an electronics device that includes a display. Power conservation systems and methods described herein alter video information in one or more inactive portions of a display area such that the alteration decreases power consumption. The invention finds use with many electronics devices, such as portable computing devices powered from a battery or other limited source of power. Since video output often dominates power consumption for an electronics device, decreasing display power consumption may extends battery longevity for the portable device.

Adaptive shading in a graphics processing pipeline
ActiveUS20150170408A1Fine granularityConsumes less powerProcessor architectures/configurationImage generationGraphicsGranularity
One embodiment of the present invention includes a parallel processing unit (PPU) that performs pixel shading at variable granularities. For effects that vary at a low frequency across a pixel block, a coarse shading unit performs the associated shading operations on a subset of the pixels in the pixel block. By contrast, for effects that vary at a high frequency across the pixel block, fine shading units perform the associated shading operations on each pixel in the pixel block. Because the PPU implements coarse shading units and fine shading units, the PPU may tune the shading rate per-effect based on the frequency of variation across each pixel group. By contrast, conventional PPUs typically compute all effects per-pixel, performing redundant shading operations for low frequency effects. Consequently, to produce similar image quality, the PPU consumes less power and increases the rendering frame rate compared to a conventional PPU.

Power Control of Servers Using Advanced Configuration and Power Interface (ACPI) States
ActiveUS20090055665A1Shorten speedConsumes less powerEnergy efficient ICTServersPower controlSatellite
A method of managing power consumption by a plurality of blade servers within a processing system. The speed of at least one of the plurality of blade servers is reduced in response to the processing system reaching a power or thermal threshold. At least one of the plurality of blade servers is identified as not being critical to maintain in a working state and the critical blade server is put in a sleep state. A satellite management controller may control blade server power consumption and heat generation in various ways that combine processor speed-stepping and control of processor sleep states. Known sleep states save more power than speed-stepping by turning off the processor and / or volatile memory. The processor speed and sleep-states of at least one non-critical blade server, and optionally the processor speed of a critical processor, may be changed in order to control the power consumption below a power threshold or control the temperature below a thermal threshold.
