Latest Patents
Among his latest patents is a method for reducing crosstalk in image sensors using implant technology. This patent describes an image sensor semiconductor device that includes a semiconductor substrate with a first-type conductivity. A plurality of sensor elements is formed within this substrate, and an isolation feature is created between them. An ion implantation process is utilized to form a doped region that underlies the isolation feature, employing at least two different implant energies.
Another notable patent is a method to optimize substrate thickness for image sensor devices. This method involves fabricating an image sensor device by providing a substrate with a front and back side. The process includes patterning a photoresist on the front side to define an opening, performing an implantation process through this opening, and forming a light sensing feature adjacent to the doped isolation feature. The substrate is then thinned from the back side to ensure that its thickness does not exceed twice the depth of the isolation feature.
