Abstract :
A high-speed production die sort system developed for wafer probing of 12 GHz high-gain MMIC (monolithic microwave IC) receivers is described. The purpose of the system is to reduce manufacturing costs and increase throughput by eliminating noncompliant die early in the manufacturing process. Another important function of the system is to automatically provide process and design information which can be used for yield enhancement through design and process improvements. Over the course of production of the MMIC receiver, yields have more than doubled, largely as a result of the die sort data that has been fed back to the engineering and manufacturing departments. The test time is reduced to three seconds per die, without sacrificing the accuracy of the measurement.<>
