Abstract
A high-voltage LDMOS device with voltage linearizing field plates and methods of manufacture are disclosed. The method includes forming a continuous gate structure over a deep well region and a body of a substrate. The method further includes forming oppositely doped, alternating segments in the continuous gate structure. The method further includes forming a contact in electrical connection with a tip of the continuous gate structure and a drain region formed in the substrate. The method further includes forming metal regions in direct electrical contact with segments of at least one species of the oppositely doped, alternating segments.
