Integration of high-Q inductors in a latch-up resistant CMOS technology

Inductors fabricated using CMOS technologies based on epi/p/sup +/ substrates are severely degraded because of eddy current losses in the substrate. We propose and demonstrate a modified substrate structure, which addresses the conflicting goals of high inductor quality-factor and high latch-up immunity. Results include fabricated inductors with Q-factor as high as 16.

Simulation of semiconductor quantum well lasers

A 2D bulk and quantum well laser simulation tool, based on the Bell Laboratories electron device simulator PADRE, has been developed. PADRE contains a suite of robust programs for obtaining self-consistent solutions of the Drift Diffusion equations. To this suite has been added programs for calculating the optical intensity inside the laser, the capture and emission rates between bound and free carriers, the interaction between the confined carriers and the optical field, and a set of ne, powerful schemes for obtaining rapid convergence of the nonlinear equations of the model. This paper describes the augmented program in its present form, gives examples of its present abilities and limitations, and discusses some illustrative results to show features of the simulation tool.

The transistor´s discovery and what´s ahead

In December of 1947 the invention of the transistor initiated the electronics revolution of the 20 century. On its fiftieth anniversary, this paper reviews the history of the transistor s discovery and the subsequent breakthroughs which led to integrated circuit and the remarkable information processing and storage capabilities of today. Prospects for continued progress are reviewed, including key technical challenges. It is anticipated that R&D innovations will drive miniaturization into at least the second decade of the next century.

Integrated communications microsystems

This presentation reviews the motivation, current state-of-the-art, and outlook for electronic and optoelectronic technologies that drive communications integration on what was traditionally a microelectronic scale, enabling continued and unprecedented improvements in wired and mobile connectivity.
