چکیده

In the current communications market, there exists a great demand for devices, which function as passive signal processing units. High performance and small size are identified to be the bottlenecks to meet market demand in communications area[1,3]. MEMS or micromachining technology can yield small, low weight and high performance components to replace the currently used off-chip components. This paper describes the micromechanical devices currently under intense research at IMEC. These include RF-MEMS switches, tuneable capacitors, MEMS resonators and their derived units such as bandpass filters etc. Micro mechanical resonators are realised using polySi (and poly SiGe ) surface micromachining and RF-MEMS components are realised from metal surface micromachining technology. Keywords— RF-MEMS, switch , micromechanical resonators.

Advanced Metal Gate/High-K Dielectric Stacks for High-Performance CMOS Transistors

1. Abstract We have successfully engineered n-type and p-type metal electrodes with the correct work functions on high-K gate dielectrics for high-performance CMOS applications. The resulting metal gate/high-K dielectric stacks have i) equivalent oxide thickness (EOT) of 1.0nm with negligible gate oxide leakage, ii) desirable transistor threshold voltages for n-and p-channel MOSFETs, and iii) t...
