Title: Innovations by Timothy Vasen in Field Effect Transistor Technology

Introduction

Timothy Vasen, located in Tervuren, Belgium, is a prominent inventor in the semiconductor industry. With an impressive portfolio of 20 patents, Vasen has significantly contributed to the advancement of field effect transistor (FET) technology, particularly through innovative methods involving carbon nanotubes.

Latest Patents

Among Vasen's latest patents is a groundbreaking method for manufacturing a field effect transistor using carbon nanotubes. This process involves creating a gate-all-around field effect transistor (GAA FET) by forming a fin structure comprising multiple stacked structures. Each of these structures includes a dielectric layer, a carbon nanotube (CNT) positioned above the dielectric layer, and a support layer above the CNT. The method continues with the formation of a sacrificial gate structure over the fin structure and an isolation insulating layer, leading to the establishment of a source/drain opening. In a novel approach, the support layer is removed from the stacked structures within this opening, allowing for the creation of a source/drain contact layer that interacts directly with portions of the CNT while maintaining a dielectric barrier.
