The film is applied to interconnection test devices without using an oxide-cap. The k remains as low as 3.3, showing that an equivalent capacitance reduction with conventional materials (k=2.5-2.9) can be achieved using a simpler and more reliable structure.","PeriodicalId":287825,"journal":{"name":"Proceedings of the IEEE 2000 International Interconnect Technology Conference (Cat.

In this paper, we present a novel RF/wireless interconnect system that provides a unique solution to those system needs. Unlike the traditional \"passive\" metal interconnect, the \"active\" RF/wireless interconnect is based on near-field capacitive coupling, low loss and dispersion-free microwave signal transmission and modern multiple-access algorithms. The proposed RF/wireless interconnect promises ultra-broad bandwidth (up to 100 GHz), simultaneous multi-I/O communications (up to 50/50 I/O sub-channels per shared microwave transmission medium) and reconfigurable network (programmable based on Frequency and/or Code Division Multiple Access). As the first step to prove the feasibility, we have realized a 2/spl times/2 CDMA transceivers based on 0.35 /spl mu/m MOSIS CMOS process, which demonstrates the desired functions of capacitive coupling, guided wave transmission and reconfigurable multiple access.","PeriodicalId":287825,"journal":{"name":"Proceedings of the IEEE 2000 International Interconnect Technology Conference (Cat.

The integration of thick metal lines is also discussed, for the upper levels of interconnects. This study shows that the VF architecture has the best via chain yield, regardless of the test configuration, and allows to pattern thick metal DD structures with high yield.
