A flexible 3-inch fabrication line for InP-based HEMT and HBT MMIC production

We discuss the issues related to fabrication of InP based MMICs for government and commercial production applications. InP based MMICs offer unique advantages for many government systems which include lower noise figure, lower DC power consumption and higher linearity. Under the MAFET program, TRW is bringing both InP HEMT and InP HBT-based MMICs from a R&D state into production capability. Manufacturing issues will be addressed from a critical node point of view, where critical nodes are defined as those process steps with the greatest impact on the MMIC performance and yield.
