Abstract : The ICs/MMICs attained importance in the field of microelectronics as these play a major role in the aerospace industry. The reliability of the ICs/MMICs becomes the critical issue because of complex material properties. A methodology has to be adopted which encompasses the qualification of ICs/MMICs for their use in the areas of strategic importance. A three-step procedure, which includes the process qualification, product qualification, and product acceptance is followed. The process qualification outlines a procedure that the foundry should follow to assure the quality, uniformity, and reproducibility from a specific process. Product qualification involves a set of simulations and measurements to establish the electrical, thermal, and reliability characteristics of a particular circuit design. Lastly, product acceptance is a series of tests performed on the deliverables.
