    Abstract

    In this work we present a new device: the boost transistor. The boost transistor is an LDMOS transistor that is controlled by a separate field plate boost electrode that reduces the specific on-resistance RonA. By applying a positive voltage Vboost, this electrode creates an accumulation layer in the drain extension of the device. Compared to the single gate device, the boost transistor results in a specific on-resistance RonA reduction of 15% without requiring any process modification, as is demonstrated by measurements and TCAD simulations. The on-state efficiency with respect to standard LDMOS designs is enhanced and a driving circuit is proposed maintaining the breakdown voltage at 70V.
