Abstract
Disclosed is a layer arrangement () within an insulating trench, which insulates circuits with little distortion while being suitable for electrically insulating high-voltage power components () relative to low-voltage logic elements () that are integrated on the same chip (). Also disclosed is the production of a sequence of alternating vertical layers in a trench (T). The electric strength for high voltages is improved while the influence of defects created by distortions of substrate disks is prevented.
