Abstract: Among other things, one or more semiconductor arrangements and techniques for forming such semiconductor arrangements are provided herein. A semiconductor arrangement comprises a cap wafer, a microelectromechanical systems (MEMS) wafer, and a complementary metal-oxide-semiconductor (CMOS) wafer. The MEMS wafer comprises a thermal insulator air gap formed between a sensing layer and a membrane. An ambient pressure chamber is formed between the CMOS wafer and the membrane of the MEMS wafer. The ambient pressure chamber is configured as a second thermal insulator air gap. The thermal insulator air gap and the second thermal insulator air gap protect portions of the semiconductor arrangement, such as the MEMS wafer, from heat originating from the CMOS wafer, which can otherwise damage such portions of the semiconductor arrangement. In some embodiments, one or more buffer layers are formed over the cap wafer as stress buffers.

Abstract: A signal processing apparatus includes an initial detecting module, a mixer, a symbol rate detecting module, a judging module and a correcting module. The initial detecting module determines an initial carrier frequency offset of an input signal according to a spectrum of the input signal. The mixer adjusts the input signal according to the initial carrier frequency offset to generate a frequency-compensated signal. The symbol rate detecting module determines a symbol rate of the input signal. The judging module judges whether the initial carrier frequency offset is correct according to the frequency-compensated signal. When a judgment result of the judging module is negative, the correcting module determines a corrected carrier frequency offset according to the symbol rate and the spectrum.

Abstract: The present disclosure relates to a top-down method of forming a nanowire structure extending between source and drain regions of a nanowire transistor device, and an associated apparatus. In some embodiments, the method provides a substrate having a device layer disposed over a first dielectric layer. The device layer has a source region and a drain region separated by a device material. The first dielectric layer has an embedded gate structure abutting the device layer.
