Latest Patents

Witnik holds a patent for a reflective semiconductor device with mirror elements having two oxide layers over an aluminum layer. This invention includes an integrated circuit (IC) structure and a pair of mirror elements that are strategically placed over the IC structure. The design features a trench separating the mirror elements, with each element comprising a mirror layer of aluminum and a low-temperature oxide (LTO) layer. A high-temperature oxide (HTO) layer fills the trench and covers the mirror elements, while a liquid crystal layer provides a liquid crystal on semiconductor (LCOS) device. This two-oxide layer design effectively prevents mirror layer creep and agglomeration during the formation of the HTO layer, ensuring a suitable surface for LCOS assembly without the need for specialized alloys.
