发明名称 FILM-ASSIST MOLDED GEL-FILL CAVITY PACKAGE WITH OVERFLOW RESERVOIR
摘要 A semiconductor device package having a cavity formed using film-assisted molding techniques is provided. Through the use of such techniques the cavity can be formed in specific locations in the molded package, such as on top of a device die mounted on the package substrate or a lead frame. In order to overcome cavity wall angular limitations introduced by conformability issues associated with film-assisted molding, a gel reservoir feature is formed so that gel used to protect components in the cavity does not come in contact with a lid covering the cavity or the junction between the lid and the package attachment region. The gel reservoir is used in conjunction with a formed level setting feature that controls the height of gel in the cavity. Benefits include decreased volume of the cavity, thereby decreasing an amount of gel-fill needed and thus reducing production cost of the package.
