A packaged semiconductor chip including the chip, and a package element such as a heat sink is made by connecting flexible leads between contacts on the chip and terminals on a dielectric element such as a sheet or plate and moving the sheet or plate away from the chip, and injecting a liquid material to form a compliant layer filling the space between the package element and the dielectric element, and surrounding the leads. The dielectric element and package element extend outwardly beyond the edges of the chip, and physically protect the chip. The assembly may be handled and mounted by conventional surface mounting techniques. The assembly may include additional circuit elements such as capacitors used in conjunction with the chip.

Semiconductor package with heat sink

A plurality of separate semiconductor chips, each having a contact-bearing surface and contacts on such surface, are disposed in an array so that the contact-bearing surfaces face and define a first surface of the array. A flexible, dielectric sheet with terminals thereon overlies the first or contact bearing surface of the semiconductor chips. Elongated leads are disposed between the dielectric element and the semiconductor chips. Each lead has a first end connected to a terminal on the dielectric element, and a second end connected to a contact on a semiconductor chip in the array. All of the leads are formed simultaneously by moving the dielectric element and the array relative to one another to simultaneously displace all of the first ends of the leads relative to all of the second ends. The dielectric element is subdivided after the forming step so as to leave one region of the dielectric element connected to each chip and thereby form individual units each including one chip, or a small number of chips.
