Latest Patents

One of his latest patents is titled "Optical waveguide and coupler apparatus and method of manufacturing the same." This invention involves a trench formed in a bulk semiconductor substrate, such as a bulk silicon substrate. A bottom cladding layer is created within the trench, followed by the formation of a core region on top of the bottom cladding layer. Additionally, a reflective element, like a distributed Bragg reflector, can be integrated beneath the coupler device and/or the waveguide device. This integration allows for seamless incorporation of optical devices with other components on a chip, particularly in DRAM memory circuit chip die.

Another notable patent is the "Method of forming nonvolatile memory device having floating gate and related device." This method outlines the process of manufacturing a non-volatile memory device, which includes forming isolation patterns that define an active region on a substrate. A floating gate pattern is then created on the active region, followed by the formation of a gate line on the floating gate pattern. The floating gate pattern is designed to be self-aligned on the active region, with an impurity ion concentration that decreases as it approaches the active region.
