Latest Patents

One of his latest patents is an imaging device that includes a plurality of first absorption layers designed to absorb infrared rays within a specific wavelength range. This device generates pixel signals for multiple pixels. Additionally, it features at least one second absorption layer that absorbs infrared rays of a different wavelength range, producing a common pixel signal. The device also incorporates first electrodes to extract pixel signals from the first absorption layers and a second electrode for the common pixel signal.

Another notable patent is a method for growing a HgCdTe epitaxial layer on a semiconductor substrate. This method involves creating a crystalline CdTe semiconductor layer on a substrate, such as sapphire, which does not interdiffuse with the materials in the semiconductor layer. The substrate is then placed in an enclosure with a Hg-Cd-Te source rich in Te, and both are heated to establish three-phase equilibrium conditions. This process allows for the conversion of the CdTe layer into a ternary semiconductor compound, which is useful as a sensing device.
