Abstract :
The results of a yield evaluation programme are described in which prime yield determining factors affecting MMIC production were examind. This is the first such exercise reported on a major European GaAs foundry. A two-stage reactively matched X-band amplifier and an S-band low noise amplifier have been used as the yield evaluation vehicles. Results will be presented detailing yields obtained at all stages from initial process monitoring to final RF testing.
