Abstract: A process for fabricating an integrated circuit package includes selectively etching a leadframe strip to define a die attach pad and a plurality of contact pads. At least one side of the die attach pad has a plurality of spaced apart pad portions. A semiconductor die is mounted to the die attach pad and wires are bonded from the semiconductor die to respective ones of the contact pads. A first surface of the leadframe strip, including the semiconductor die and wire bonds, is encapsulated in a molding material such that at least one surface of the leadframe strip is exposed. The integrated circuit package is singulated from a remainder of the leadframe strip.

Abstract: An integrated circuit package having a selectively etched leadframe strip defining a die attach pad and a plurality of contact pads, at least one side of the die attach pad having a plurality of spaced apart pad portions; a semiconductor die mounted to the die attach pad and wires bonding the semiconductor die to respective ones of the contact pads; a first surface of the leadframe strip, including the semiconductor die and wire bonds, encapsulated in a molding material such that at least one surface of the leadframe strip is exposed, and wherein solder paste is disposed on said contact pads and said at least one side of said die attach pad.

Abstract: A method of fabricating an integrated circuit package. The method includes providing a first leadframe and a second leadframe, laminating the second leadframe to a portion of the first leadframe in order to create a multi-layer laminated leadframe, and mounting a semiconductor die on another portion of the first leadframe.

Abstract: A leadless plastic chip carrier is constructed by half etching one or both sides of the package design onto a leadframe strip so as to create unique design features such as power and/or ground ring surrounding the die attach pad, interlocking rivet head construction for the contact pads, and an interlocking pattern for the die attach pad. After wire bonding and molding, a further etching is performed to isolate and expose contact pads. Singulation of individual chip packages from the leadframe strip is then performed by saw singulation or die punching.

Abstract: A process for fabricating a leadless plastic chip carrier includes selectively depositing a plurality of base layers on a first surface of a base of a leadframe strip to at least partially define a die attach pad and at least one row of contact pads. At least one further layer is selectively deposited on portions of the plurality of layers to further define at least the contact pads. The leadframe strip is then treated with a surface preparation. A semiconductor die is mounted to the die attach pad, followed by wire bonding the semiconductor die to at least the contact pads. Molding the semiconductor die, the wire bonds, the die attach pad and the contact pads on the surface of the leadframe strip, in a molding compound follows. The leadframe strip is etched to expose the contact pads and the die attach pad and the leadless plastic chip carrier is singulated from a remainder of the leadframe strip.

Abstract: A process for fabricating an integrated circuit package. At least a first side of a leadframe strip is selectively etched to define portions of a die attach pad and at least one row of contacts adjacent the die attach pad. A carrier strip is laminated to the first side of the leadframe strip and a second side of the leadframe strip is selectively etched to thereby define a remainder of the die attach pad and the at least one row of contacts. A semiconductor die is mounted to the die attach pad, on the second side of the leadframe strip and the semiconductor die is wire bonded to ones of the contacts. The second side of the leadframe strip is encapsulating, including the semiconductor die and wire bonds, in a molding material. The carrier strip is removed from the leadframe strip and the integrated circuit package is singulated from a remainder of the leadframe strip.

Abstract: A process for fabricating a leadless plastic chip carrier includes selectively etching at least a first surface of a leadframe strip to partially define at least a plurality of contact pads and a die attach pad; selectively plating at least one layer of metal on a second surface of the leadframe strip, on an undersurface of at least the plurality of contact pads and the die attach pad; mounting a semiconductor die on the first surface, on the partially defined die attach pad; wire bonding the semiconductor die to ones of the contact pads; encapsulating the wire bonds and the semiconductor die in a molding material such that the molding material covers a first portion of the die attach pad and first portions of the contact pads; selectively etching a second surface of the leadframe strip to define a second portion of the contact pads and a second portion of the die attach pad by etching the second surface with the at least one layer of metal resisting etching; and singulating the leadless plastic chip carrier

Abstract: A leadless plastic chip carrier is constructed by half etching one or both sides of the package design onto a leadframe strip so as to create unique design features such as power and/or ground ring surrounding the die attach pad, interlocking rivet head construction for the contact pads, and an interlocking pattern for the die attach pad. After wire bonding and molding, a further etching is performed to isolate and expose contact pads. Singulation of individual chip packages from the leadframe strip is then performed by saw singulation or die punching.
