摘要: A method for producing a SiGe stressor with high Ge concentration is provided. The method includes providing a semiconductor substrate with a source area, a drain area, and a channel in between; depositing the first SiGe film layer on the source area and/or the drain area; performing a low temperature thermal oxidation, e.g., a high water vapor pressure wet oxidation, to form an oxide layer at the top of the first SiGe layer and to form the second SiGe film layer with high Ge percentage at the bottom of the first SiGe film layer without Ge diffusion into the semiconductor substrate; performing a thermal diffusion to form the SiGe stressor from the second SiGe film layer, wherein the SiGe stressor provides uniaxial compressive strain on the channel; and removing the oxide layer. A Si cap layer can be deposited on the first SiGe film layer prior to performing oxidation.

摘要: A frequency doubler receiving an in-phase oscillating signal and an inverse oscillating signal and generating an output signal oscillating at a multiplied frequency, accordingly. The frequency doubler has a first transistor, a second transistor, a first inductor and a second inductor. A first terminal of the first transistor and a first terminal of the second transistor are at a common voltage. The frequency doubler receives the in-phase oscillating signal and the inverse oscillating signal via control terminals of the first and second transistors. The first and second inductors couple a second terminal of the first transistor and a second terminal of the second transistor to an output terminal of the frequency doubler, respectively. The first and second inductors may be separate inductance devices or, in another case, be implemented by a symmetric inductor.
