Latest Patents

Eisenbrandt's latest patents focus on advancements in LDMOS (Lateral Diffused Metal Oxide Semiconductor) technology. One of his notable inventions outlines devices and methods for creating a power transistor structure with a shallow source region. This process involves implanting a dopant of a first dopant polarity into a drift region located on the source side of a gate structure to form a body region that is self-aligned with, and extends under, the gate structure. This innovative design helps to produce a shallow body region where a source side hybrid contact alleviates punch-through issues and mitigates the triggering of a parasitic bipolar. Additionally, a retrograde body well of the same dopant polarity enhances the electric field profile of the shallow self-aligned body region, allowing for the production of a variety of effective power transistor structures.
