Latest Patents

One of her latest patents is an advanced image sensor that includes a pixel division structure, a light sensing element, a transistor, a color filter array layer, and a microlens. The pixel division structure extends through a substrate in a vertical direction, defining unit pixel regions where unit pixels are formed. Each unit pixel region contains a light sensing element, while the transistor is formed on the substrate. The color filter array layer, located under the substrate, includes color filters, and the microlens is positioned beneath this layer. The transistor features a gate structure on an active fin protruding from the substrate's upper surface, with source and drain regions adjacent to the gate structure.

Another notable patent is for a semiconductor device and its fabrication method. This invention comprises a first trench formed in a substrate, with a first insulating film on the sidewalls and bottom surface of the trench, but not on the top surface. A first conductive film partially fills the trench, with the insulating film having portions that overlap and do not overlap the conductive film. The non-overlapping portion contains fixed charges, enhancing the device's functionality.
