Latest Patents

One of his latest patents is titled "Method for manufacturing field effect transistors." This invention discloses a process where a thick mesa of dielectric material is grown on a semiconductor substrate. Two or more layers of polycrystalline silicon are then grown on the vertical sides of the mesa, serving a masking function to define the gate region of the transistor with high accuracy. The mesa and the polycrystalline layers remain in the final device, enhancing its performance.

Another significant patent is "Epitaxially extended polycrystalline structures utilizing a predeposit." This process aims to reduce microcracks and microvoids in the formation of polycrystalline structures from initial layers of amorphous silicon through annealing. By maintaining the thickness of the amorphous silicon below 1000 angstroms, the spacing between contrasting materials forming the crystal grains can be minimized during annealing. The resultant equiaxial grains serve as seed crystals for the growth of silicon into the desired layer thickness.
