Re-engineering silicon: Si-Ge heterojunction bipolar technology

Article Abstract:

Devices made by doping the silicon transistor with germanium combine the low cost and high strength of silicon with the high speeds and cut-off frequencies of III-V compound semiconductors. They are manufactured through ultrahigh vacuum chemical-vapor deposition technique with equipment that is common to advanced silicon fabrication facility. The ICs go into fast converters, photonics and cryogenic electronics.

Re-engineering engineering education

Article Abstract:

Engineering schools are working with private industry and government representatives to redesign curricula. In the US emphasis is placed on teaching students to work as a team and to communicate within interdisciplinary groups. The American Society for Engineering Education published guidelines for new education. Canada's Telecommunications Research Institute of Ontario is a model of the new teaching.
