Latest Patents

Among his latest patents is an innovative image sensor and method for fabricating the same. This image sensor comprises a substrate, a plurality of photoelectric transducer devices, an interconnect structure, at least one dielectric isolator, and a back-side alignment mark. The substrate features a front-side surface and a back-side surface opposite to the front-side surface. The interconnect structure is positioned on the front-side surface, while the photoelectric transducer devices are formed on the same surface. The dielectric isolator extends downwards into the substrate from the back-side surface to isolate the photoelectric transducer devices. Additionally, the back-side alignment mark extends downwards into the substrate from the back-side surface, referencing a front-side alignment mark previously formed on the front-side surface.

Another notable patent involves a method of making a CMOS image sensor and a method of suppressing dark leakage and crosstalk for a CMOS image sensor. In this process, an implantation is performed on the substrate under isolation structures, each disposed between two adjacent photosensor cell structures. This destructive implantation creates lattice effects and trap centers, and no defect repair process is conducted afterward. The implants can reside at the isolation structures or in the substrate beneath them, effectively suppressing dark leakage and crosstalk.
