  • Publication number: 20150251900
    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 cap wafer comprises a first spring structure and the MEMS wafer comprises a second spring structure. The first spring structure and the second spring structure relieve stress as portions of the semiconductor arrangement, such as a membrane and a poly layer, move. An ambient pressure chamber is formed between the CMOS wafer and the MEMS wafer as a thermal insulation air gap to protect the MEMS wafer from heat originating from the CMOS wafer. The ambient pressure chamber is connected to ambient air, such as for CMOS outgassing relief.

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.

  • Patent number: 9131198
    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.

  • Patent number: 9121820
    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. One or more masking layers are selectively formed over the device layer to define a nanowire structure. The device layer is then selectively etched according to the one or more masking layers to form a nanowire structure at a position between the source region and the drain region. By forming the nanowire structure through a masking and etch process, the nanowire structure is automatically connected to the source and drain regions.

  • Publication number: 20150243730
    Abstract: The present disclosure relates to an integrated chip having a titanium nitride film that provides for a reduced leakage path, and an associated method of formation. In some embodiments, the integrated chip comprises a semiconductor substrate. A titanium nitride film is disposed over the semiconductor substrate. The titanium nitride film comprises a plurality of titanium nitride layers having grain boundaries abutting vertical column-like structures of titanium nitride. The grain boundaries are discontinuous between a top surface of the titanium nitride film and a bottom surface of the titanium nitride film. The discontinuity of the grain boundaries between the different titanium nitride layers reduces leakage paths through the titanium nitride film (e.g., and thereby can improve operation of a MIM capacitor having titanium nitride electrodes).
