| 20100033244 | POWER AMPLIFIER SYSTEM AND CONTROL METHOD AND CONTROL DEVICE THEREOF - A power amplifier system, a control method thereof, and a control device thereof are provided. The power amplifier system operates in a non-linear switching mode according to an envelope amplitude of an input signal under control of the control device. When the power amplifier is operated in the non-linear switching mode, a supply voltage and an input signal of the power amplifier are provided to the power amplifier by the control device according to pre-measured properties of the power amplifier so as to equip the power amplifier with a high power-added efficiency (PAE) and a better linearity. | 02-11-2010 |

| 20100221494 | METHOD FOR FORMING SEMICONDUCTOR LAYER - A method for forming a semiconductor layer includes following steps. First, an epitaxial substrate having at least a first growth region and at least a second growth region is provided. An area ratio of C plane to R plane in the first growth region is greater than 52/48. An epitaxial process is then performed on the epitaxial substrate to form a semiconductor layer. During the epitaxial process, a semiconductor material is selectively grown on the first growth region, and then the semiconductor material is laterally overgrown on the second growth region and covers the same. | 09-02-2010 |
