With a total of three patents to her name, she has made significant advancements in the field, particularly in improving the performance and efficiency of semiconductor devices.

Latest Patents

One of her latest patents is the "Semiconductor on Insulator Laser Process." This innovative process involves applying a beam of radiant energy, such as a laser beam, to an epitaxial silicon island on a silicon on sapphire device before the formation of overlying layers of oxide and metal. The energy beam alters the crystal structure of the silicon island, enhancing the mobility of carriers and thereby improving the speed of transistors formed on the island. Additionally, the energy beam causes the material at the edge of the silicon island to reflow, which reduces the slope of the edge face and smooths the surface. This results in improved aluminum step coverage and eliminates a V-shaped groove in the insulation layer, ultimately increasing processing yield.

Another significant patent is the "Electron Beam Annealing of Metal Step Coverage." This invention addresses defects in the metal step coverage of thin film semiconductor devices by annealing the metal layer with a pulsed electron beam. This technique effectively removes defects, enhancing the reliability and performance of semiconductor devices.
