In this paper, analysis to the temperature rise in three ULSI interconnect structures of 50nm node technology have been carried out by using the compact quasi-analytic model we developed. Although the error in analyzing structure I is increased to 7.7%, the results still mean much for temperature rise prediction in interconnect design. Thick interlayer is the main causes to make the heat transfer conditions of interconnect severely rugged. The investigation to the thermal conductivity of the interlayer reveals that temperature rise decays in two order exponential way and when k>0.1 w//spl deg/Cm, the temperature rise increases extremely fast. New dielectric materials with low k but relatively less porous are desired in the interconnect structure for future 45nm node technology and beyond.

A, novel MEMS gas sensor including a PZT thin film layer and a zeolite layer is developed in this paper, which shows effective combination of high sensitivity and high selectivity. Working in resonating mode, the sensor depicts the mass loading due to molecular adsorption of the zeolite by the frequency shift. The relationship between the frequency shift in percent and the concentration of Freon is linear. The minimum mass loading of 3.5 /spl times/ 10/sup -9/ and the sensitivity of -0.0024%/ppm can be determined from the experimental results.

A new algorithm of vector quantization (VQ) suitable for VLSI implementation is proposed. In this algorithm, a large number of codewords will be rejected before computing its MAE while the image quality is maintained. A criterion of distortion measure, the presorted codebook, a nearest neighbors search algorithm and a dichotomy search method adopted in the proposed algorithm have resulted in a considerable reduction in the complexity of VLSI implementation.
