Abstract: A quad flat no-lead (QFN) integrated circuit package is provided. The QFN integrated circuit package includes an insulating adhesive layer, a semiconductor chip attached to the insulating adhesive layer, and a lead frame bent to be electrically connected to the semiconductor chip and attached to the insulating adhesive layer. The QFN integrated circuit package according the present invention does not use a die paddle and is thus thin. Accordingly, the volume of the package can be minimized.

Abstract: A method of manufacturing a semiconductor package having no chip pad includes preparing a polyimide tape on which an adhesive layer is arranged; forming lead members on the adhesive layer so as to form a plurality of semiconductor packages in a matrix form; attaching the polyimide tape to a carrier; performing wire bonding to mount semiconductor chips on the polyimide tape and connect the lead members and the semiconductor chips; forming an encapsulation member to encapsulate the semiconductor chips, the lead members, and wires; detaching the encapsulation member from the carrier and the polyimide tape; forming conductive layers each on a surface of the lead member exposed through a surface of the encapsulation member; and performing a singulation process on the encapsulation member with the conductive layers formed thereon to define unit semiconductor packages.
