With a total of 2 patents, his work has advanced the capabilities of microfabrication processes.

Latest Patents

One of his latest patents is a micro pipe manufacturing method. This innovative method involves fabricating micro pipes on a semiconductor wafer or other substrate. The process begins with the deposition of a base layer on the substrate, which is then etched to create a trench that exposes the substrate's surface. A photoresist layer of selected thickness is deposited over the base layer and trench. In a crucial curing step, the photoresist is irradiated with ionizing radiation, causing nitrogen gas to outgas from the photoresist layer. This facilitates the buckling of the photoresist layer into an arcuate bubble, defining the semispherical micro pipe structure.

Another significant patent is the method for manufacturing micro-optical mirror arrays. This method produces a spheroidal shaped micro-array assembly by providing a substrate with frontside patterned openings. A photosensitive layer is blanket deposited over the substrate, including the patterned openings. The photosensitive layer is then exposed to ionizing radiation for a predetermined time, leading to outgassing that separates the photosensitive layer from the substrate. This process results in a spheroidal shaped photosensitive layer portion, which is subsequently covered with a mirror layer to preserve its shape before removing the photosensitive layer.
