  • Publication number: 20140264588
    Abstract: The present disclosure relates to a method of ultra-high voltage UHV device formation which utilizes a composite step oxide as a gate oxide to achieve isolation of the gate and drain-side spacer from the drain region. The thickness of the step gate oxide improves device breakdown voltage, and allows for the drain to be self-aligned to the gate, thus reducing device drift region and improves device on state resistance. The composite isolation layer comprises two or more dielectric layers which are formed through a series of deposition and etch steps including thermal oxidation and chemical vapor deposition. The composite isolation layer may then be etched to form a self-align structure which utilizes the spacers as hard mask to achieve a reduced device pitch relative to some prior art methods. A thicker gate oxide under one or both spacers can improve yield and high temperature operating life of the UHV device.
