Title: Sumiko L Poust: Innovator in Semiconductor Technology
Introduction
Sumiko L Poust is a prominent inventor based in Hawthorne, CA (US). She has made significant contributions to the field of semiconductor technology, holding a total of 2 patents. Her work focuses on enhancing the performance and efficiency of field-effect transistors (FETs).
Latest Patents
One of her latest patents is for a "Multiple layer side-gate FET switch." This innovative FET design includes a base and first and second stacked layer groups, each featuring a nonconductive layer and a semiconductive layer adjacent to it. The design incorporates source and drain electrodes that are in low resistance contact with the semiconductive layers. Additionally, first and second parallel trenches extend vertically between the source and drain electrodes, creating access to the edges of the layers. A continuous conductive side gate engages the edges and the top of a defined ridge, enhancing the figure of merit for the FET as the number of layer groups increases.
Another notable patent is for a "Method of forming a gate contact." This method provides a way to form a gate contact for a compound semiconductor device, allowing for tunability in the size of the wing contact portion while maintaining the operational frequency. The process includes additional conductive material applications to increase the cross-sectional area of the wing contact portion, thereby reducing gate resistance.
