The invention provides a taped lead frame for use in manufacturing electronic packages. The taped lead frame is composed of a tape and a lead frame formed from a plurality of individual metal features attached to the tape and arranged in a footprint pattern. The method of making the invention enables the thickness of conventional frames to shrink significantly to result in thinner packages for improved heat dissipation and shorter geometries for improved electrical performance. A plurality of such lead frames are arranged in an array on a sheet of tape and each lead frame is separated from surrounding lead frames by street regions on the tape such that no metal feature extends into a street region. Integrated circuit chips are attached and electrically connected to the lead frames and an encapsulant is applied, cured and dried over the lead frames and the street regions. Thereafter, the tape is removed and the lead frames are singulated by cutting through the encapsulant in the street regions to form individual packages. Singulation occurs in the street regions and does not cut into any metal feature forming the lead frame.

A semiconductor package substrate is provided, which can meet the move toward high integration of semiconductors. A nickel layer is plated on an electroplated copper foil to form a wiring pattern. An LSI chip is mounted on the copper foil, and terminals of the LSI chip and the wiring pattern are connected by wire bonding, followed by sealing with a semiconductor-sealing epoxy resin. Only the copper foil is dissolved away with an alkali etchant to expose nickel. With a nickel stripper having low copper-dissolving power, the nickel layer is removed to expose the wiring pattern. A solder resist is coated, and a pattern is formed in such a way that connecting terminal portions are exposed. Solder balls are placed at the exposed portions of the wiring pattern and are then fused. The wiring pattern is connected to an external printed board via the solder balls.
