Latest Patents

One of her latest patents focuses on a thin film transistor and the method for manufacturing it. The objective of this invention is to provide a thin film transistor that features a small off current, a large on current, and high field-effect mobility. The design incorporates a silicon nitride layer and a silicon oxide layer, which is formed by oxidizing the silicon nitride layer, stacked as a gate insulating layer. Crystals grow from the interface of the silicon oxide layer of the gate insulating layer to form a microcrystalline semiconductor layer. This process results in the manufacturing of an inverted staggered thin film transistor. The growth of crystals from the gate insulating layer allows the thin film transistor to achieve high crystallinity, large on current, and high field-effect mobility. Additionally, a buffer layer is included to reduce off current, enhancing the overall performance of the device.
