Abstract: A semiconductor package includes a semiconductor chip, a die pad, an adhesive, metal wires, LOC inner leads, and standard inner leads sealed within a sealing resin. The LOC inner leads and the standard inner leads are arranged in the same plane and both are arranged along one side of the semiconductor chip. Clearance between the inner leads and the die pad larger than the total thickness of the semiconductor chip and the bonding material. Thus, a semiconductor chip having electrode pads broadly distributed can be employed and the section modulus of the semiconductor package can be increased.

Abstract: The present invention provides a semiconductor package in which a semiconductor chip, a die pad, an adhesive, metal wires, LOC type inner and standard type inner leads are sealed with a sealing resin. The LOC type inner leads and the standard type inner leads are arranged on a same plane and mixedly arranged along a side of the semiconductor chip. Clearance between the inner leads and the die pad is set to be larger than a sum of thickness of the semiconductor chip and the bonding material. Thus, a semiconductor chip having electrode pads broadly distributed and arranged thereon can be employed and the modulus of section of the semiconductor package can be enhanced.

Abstract: A wire bonding method for joining a metal wire with a bonding pad disposed on a semiconductor element by using a load and supersonic wave vibration, comprising: during interval of time from contact of the metal wire with the bonding pad to application of the supersonic wave vibration, continuously applying a first bonding load and a second bonding load which is lower than the first bonding load; and after application of the supersonic wave vibration, continuously applying a third bonding load of a size of about 50% of the load of the second bonding load and a fourth bonding load which is lower than the first bonding load and higher than the third bonding load. The reliability of the fine wire bonding joint is improved remarkably, whereby a high quality semiconductor device cna be produced at a low cost.
