Latest Patents

One of his latest patents is a method for fabricating a carrier-free semiconductor package. This innovative method involves half-etching a metal carrier to create multiple recess grooves and metal studs that serve as solder pads or die pads. Each recess groove is filled with a first encapsulant, and an antioxidant layer is formed on the metal studs. The process includes die-bonding, wire-bonding, and molding to create a second encapsulant that encapsulates the chip. This invention addresses the issue of weak and pliable copper plates, enhancing adhesion and avoiding transportation difficulties. Additionally, it reduces fabrication costs by eliminating the need for costly metals as an etching resist layer, allowing for flexible conductive trace placement on the metal carrier.
