Abstract

PURPOSE:To enable a packaging process to be accomplished with ease and at a low cost by a method wherein a plurality of semiconductor chips is directly die-bonded to a mount and then wire-bonding and resin-sealing are accomplished. CONSTITUTION:A lead frame contains as its major portions die pads 1 and 2, die pad section suspension leads 3, tie bars 4, and inner leads 5. One or more semiconductor chips are wire-bonded to the die pad sections 1 and 2, respectively. A resin-sealing process follows this process of establishing connection between semiconductor chips directly by wire-bonding. This method dispenses with intermediate circuit pattern constructing materials such as laminates, contributing to the saving of materials and manpower and realizing the economical production of resin-sealed multi-tip packages.

In recent years, a so-called multi-chip package in which two or more semiconductor chips are mounted in a resin-sealed package has been implemented. For example, as a semiconductor chip, two chips (microcontroller and memory) may be mounted in one package, or three chips (microcontroller, memory, and gate array) may be mounted.
Chips are being packaged in a single package.

When the substrate potentials of multiple semiconductor chips to be mounted are the same, there will be no problem even if the parts on the lead frame on which those chips are mounted are electrically connected, but if the substrate potentials are the same. When the voltage is not at a potential, this is achieved by using a lead frame in which a plurality of semiconductor chip mounting portions are electrically independent from each other, as shown in FIG. 1 or FIG. The connection between the electrodes formed on the semiconductor chip and the outer leads is no different from that of a normal resin-sealed package. multiple semiconductor chips,
In order to electrically connect the semiconductor chips to each other, it is also possible to connect the semiconductor chips to each other by wire bonding using the inner lead group 5 as an intermediate medium.
