Abstract:
A hybrid IGBT device having a VIGBT and LDMOS structures comprises at least a drain trenched contact filled with a conductive plug penetrating through an epitaxial layer, and extending into a substrate; a vertical drain region surrounding at least sidewalls of the drain trenched contact, extending from top surface of the epitaxial layer to the substrate, wherein the vertical drain region having a higher doping concentration than the epitaxial layer.
