Title: Innovations of Van H Lee

Introduction

Van H Lee is a notable inventor based in Beaverton, OR (US). He has made significant contributions to the field of thin film transistors, holding 2 patents that showcase his innovative approach to semiconductor technology.

Latest Patents

His latest patents include advancements in vertical multi-gate thin film transistors. These transistors feature a gate electrode pillar clad with a gate dielectric, which is further clad with a semiconductor layer. The design allows for source or drain metallization to be embedded in trenches formed in an isolation dielectric adjacent to separate regions of the semiconductor layer. This configuration enables the biasing of the gate electrode to induce one or more transistor channels within the semiconductor layer, effectively coupling the source and drain metallization. The width of the channel is proportional to the height of the gate electrode pillar, while the length is proportional to the spacing between contacts occupied by the semiconductor layer. Additionally, a memory device may include cells comprising a vertical thin film select transistor and a capacitor (1TFT-1C).

Another significant patent is for a non-planar gate all-around device and its method of fabrication. This device includes a substrate with a top surface featuring a first lattice constant. Embedded epi source and drain regions are formed on this surface, having a second lattice constant that differs from the first. Channel nanowires with a third lattice constant are formed between the embedded regions. The design includes a bottom-most channel nanowire with a bottom gate isolation formed on the substrate surface beneath it. A gate dielectric layer surrounds each channel nanowire, topped with a gate electrode.
