Abstract
Metal-oxide-semiconductor field-effect transistor (MOSFET) devices are described which have a p-type region between the p-type well regions of the device. The p-type region can be either floating or connected to the p-type well regions by additional p-type regions. MOSFET devices are also described which have one or more p-type regions connecting the p-type well regions of the device. The p-type well regions can be arranged in a various geometric arrangements including square, diamond and hexagonal. Methods of making the devices are also described.
