MONOLITHIC INTEGRATED CIRCUIT STRUCTURE INCORPORATING DIODE BRIDGE RECTIFIER

摘要

D-22646 Monolithic integrated circuit structure incorporating a full wave diode bridge rectifier of four Schottky diodes. A body of silicon includes four zones of N-type material. The first and second N-type zones are separated from each other by encircling and intervening P-type material. The third and fourth N-type zones are contiguous. A Schottky barrier is formed adjacent to the surface of each zone by a layer of a mixed silicide of deposited titanium and tungsten. A first conductive member is connected to the N-type material of the first zone and the silicide layer of the third zone. A second conductive member is connected to the N-type material of the second zone and the silicide layer of the fourth zone. A third conductive member is connected in common to the silicide layers on the first and second zones. A fourth conductive member is connected to the N-type material of the third and fourth zones. An AC voltage applied across the first and second conductive members produces a DC voltage across the third and fourth conductive members.
