GaAs heterojunction bipolar 1K gate array

This report will discuss the design, fabrication and performance of a 1K heterojunction I2L gate array with a base bar size of 3.55 × 3.80mm2, containing 1024 internal gates, 64 programmable I/O buffers and 8 pads for the power supply. For general circuit applications the layout provides 300 global wire channels: 150 each in the horizontal and vertical directions.
