Latest Patents

One of his latest patents is titled "Semiconductor device with stress relief feature and method therefor." This patent describes a method of manufacturing a semiconductor device that involves placing a package substrate on a carrier substrate, forming a frame on the package substrate, and affixing an active side of a semiconductor die on the package substrate. The design creates a cavity between the semiconductor die and the package substrate, with the frame preventing encapsulant from entering this cavity.

Another notable patent is "Die separation using adhesive-layer laser scribing." This method focuses on wafer dicing and the removal of separated integrated circuit (IC) dies from a carrier substrate. It includes mounting a wafer on a substrate using an adhesive layer, laser scribing the adhesive layer to create defect regions, and performing a breaking step to separate the adhesive layer into portions corresponding to the IC dies. This technique aims to achieve efficient adhesive-layer separation while reducing backside chipping associated with conventional blade dicing.
