Bi-Polar Transistor (BJT) Processes

The BJT processes which are currently being used by the RCIM include:

GA911 (2.5 GHz Bipolar Linear Array)

The bipolar linear array technology from Gennum Corporation is tile-based and can be used for either analog or digital applications. This technology allows designers to create semicustom IC layouts by connecting array devices using a single layer of interconnect. The layer of interconnect is used in fabrication as the programming layer for the devices. The arrays contain a selection of passive and active devices in fixed positions which are mirrored and rotated throughout the array to permit symmetrical layout. The designer manually routes the interconnect metal between individual device pins to lay out the circuit. Typical overall performance parameters for the technology are ft=2.5 GHz, Vmax=20 volts. The GA911 technology can be a useful instructional vehicle for introducing students to CAD and microelectronics.

SiGe (0.5-micron Silicon Germanium)

IBM's BiCMOS 5HP and BiCMOS 5AM process. Note that BiCMOS 5HP is a 3-metal process and BiCMOS 5AM is a 4-metal process.
