Abstract: PURPOSE: A wafer level package and a method for making the same are provided to perform a packaging process on a wafer level state by using a lead frame made of a rigid metal flat plate, and form a solder ball of a uniform height by using a solder of a paste format. CONSTITUTION: A wafer level package includes a semiconductor chip, a lead frame, a metal wire(50), a covering part(60), and a solder ball(70). Many semiconductor chips of arranging many bonding pads in a center part are mounted on a wafer. The lead frame is mounted on a wafer surface. The lead frame is a metal flat plate of a right-angled tetragon. A long-shape main opening part for exposing the bonding pads is formed along the center part of the lead frame. Many branch opening parts are formed to both sides of the main opening part in a direction perpendicular to a length direction of the main opening part. A concave groove is formed to both sides of each branch opening part. A metal pattern having a lower surface than the metal flat plate is arranged in each branch opening part. A ball land making the same plane as the metal flat plate is formed on the metal pattern positioned between the branch opening parts. Inner surface of the metal pattern positioned to the main opening part is connected to the bonding pad through the metal wire. The main opening part and the branch opening part are buried with the covering part in order to make the same plane as the ball land surface. the surface of the metal pattern is buried with the covering part. A solder ball is mounted to the ball land. A wafer is cut on the basis of the inner wall of the branch opening part, and is divided into many semiconductor chips.
