Abstract: A multi-gate structure is used and a width (d1) of a high concentration impurity region sandwiched by two channel forming regions in a channel length direction is set to be shorter than a width (d2) of low concentration impurity regions in the channel length direction. Thus, a resistance of the entire semiconductor layer of a TFT which is in an on state is reduced to increase an on current. In addition, a carrier life time due to photoexcitation produced in the high concentration impurity region can be shortened to reduce light sensitivity.

Abstract: Methods are provided for producing SiGe-on-insulator structures and for forming strain-relaxed SiGe layers on silicon while minimizing defects. Amorphous SiGe layers are deposited by CVD from trisilane and GeH4. The amorphous SiGe layers are recrystallized over silicon by melt or solid phase epitaxy (SPE) processes. The melt processes preferably also cause diffusion of germanium to dilute the overall germanium content and essentially consume the silicon overlying the insulator. The SPE process can be conducted with or without diffusion of germanium into the underlying silicon, and so is applicable to SOI as well as conventional semiconductor substrates.

Abstract: The present invention facilitates semiconductor device fabrication by providing mechanisms for utilizing different isolation schemes within embedded memory and other logic portions of a device. The isolation mechanism of the embedded memory portion is improved relative to other portions of the device by increasing dopant concentrations or reducing the depth of the dopant profiles within well regions of the embedded memory array. As a result, smaller isolation spacing can be employed thereby permitting a more compact array. The isolation mechanism of the logic portion is relatively less than that of the embedded memory portion, which permits greater operational speed for the logic.
