摘要： A heterojunction field effect transistor comprises a semi-insulating GaAs substrate, an n-InGaAs channel layer on the substrate, and a barrier layer on the n-InGaAs channel layer. The barrier layer is composed of a substantially fully depleted p-AlGaAs layer between two i-AlGaAs layers. A gate electrode is in Schottky contact with the barrier layer. Since the p-AlGaAs layer raises the barrier height in the barrier layer higher than the Schottky barrier, forward gate current is suppressed. In addition, the breakdown voltage is improved since a longer depletion region extends toward the drain side when a reverse bias is applied between the gate and the drain.

摘要： Sample chips are tested after determining the chip layout on a semiconductor wafer so that one or plural ones of untested chips are surrounded by plural ones of the sample chips that adjoin the untested samples. A good/defective judgment on the untested chips is performed by using predicted good/defective judgment results that are statistically predicted based on results of the sample test and stored statistical data of a defect generation profile including address information that indicates defective chip locations. As a result, the good/defective judgment can be performed with high accuracy even in a case where defective chips are localized in a particular region on the wafer in a concentrated manner.

摘要： There are provided an electric contact device for establishing reliable contact with ball contactors or strip contactors of a semiconductor device over contact areas of great area; a semiconductor device test socket using the electric contact device; a semiconductor module using the electric contact device; and a semiconductor device test method. A contact lead having a ring-shape or helical section is provided between a support pole and a movable pole. The movable pole is moved, to thereby bring the contact lead into an expanded state in which the diameter of the ring-shape or helical section becomes larger. A contactor is inserted into the ring-shape or helical section. The contact lead is then brought into a contacted state such that the diameter of the ring-shape or helical section becomes smaller, wherewith the contact lead is wrapped around the periphery of the contactor.
