Latest Patents
One of Tsai's latest patents is titled "Method of manufacturing active matrix LCD using five masks." This invention provides a comprehensive method for producing an active matrix liquid crystal display device that incorporates multiple thin film transistors using five distinct masks. The process involves forming gate electrodes with a first mask, creating etch stoppers over these electrodes with a second mask, and forming chain and source electrodes with a third mask. Additionally, a passivation layer with via holes is created using a fourth mask, followed by the formation of pixel electrodes with a fifth mask.
Another significant patent by Tsai is "Controlled isotropic doping of semiconductor materials." This method focuses on doping selected areas of semiconductor material during the fabrication of integrated circuit devices. The process includes placing a semiconductor substrate in a glow discharge reactor, introducing reactant gases, and subjecting these gases to a plasma discharge. The resulting dopant carrier layer, which comprises an amorphous semiconductor material, is deposited on the substrate. The thickness of this layer is controlled, and dopant atoms are driven into the selected areas of the semiconductor substrate through a controlled elevated temperature anneal.
