Latest Patents

Chiang's latest patents include a groundbreaking development in silicon carbide film for X-ray masks and vacuum windows. This invention features a layered structure designed for use in an X-ray membrane mask or a vacuum window. An intermediate amorphous layer, such as silicon dioxide, is grown on a silicon substrate, providing a stress relief medium. This structure enhances the surface properties and improves subsequent process layers by breaking the epitaxial nature of later deposited layers. The deposition of an inorganic overcoat, such as silicon carbide, on the intermediate amorphous layer results in a nearly defect-free layer with significantly reduced stress, making it suitable for X-ray lithography mask fabrication. Additionally, alternating layers of silicon carbide film and an intermediate inorganic layer, such as silicon nitride, can be deposited to achieve an even smoother silicon carbide surface and a stronger structure.
