Abstract

A semiconductor device () comprising: a substrate () having a first surface (); an n-type well () extending from the first surface () into the substrate () and configured to form a depletion region () in the substrate () around the n-type well (); an insulating layer () extending over the first surface () of the substrate () from the n-type well (), the insulating layer () configured to form an inversion layer () in the substrate () extending from the n-type well () adjacent to the first surface (); wherein a p-type floating channel stopper () is provided, configured to extend through the inversion layer () to reduce electrical coupling between the n-type well () and at least part of the inversion layer (), and is electrically disconnected from a remainder of the substrate () outside of the depletion region ().
