Embodiment Construction

[0026] The following is an explanation of related embodiments of a semiconductor device and its manufacturing method proposed according to the present invention. FIG. 1 is a schematic diagram illustrating a first embodiment. Just as shown in the schematic plan view in FIG. 1(a), the semiconductor device of the first embodiment has an LOC structure, and is provided with an on-chip semiconductor element 1, and a plurality of pins L and common lines 2a and 2b pass through the semiconductor element 1. The insulating tape T on the substrate 1a is connected to provide electrical connections for the electrode pads that handle common signals among the many electrode pads on the substrate 1a, and the bonding wire W that electrically connects the electrode pads to the pin L.

[0027] In this semiconductor device, the common line 2a constitutes a power line by being electrically connected to the electrode pad P1 connected to the power supply, and the common line 2b constitutes a ground w...

Abstract

A semiconductor device includes a plurality of electrode pads P provided on a semiconductor element 1, leads L coupled with the electrode pads via bonding wires W and common lines 2a and 2b provided on the semiconductor element 1 that achieve electrical continuity for electrode pads that handle a common signal among the plurality of electrode pads. At least the surfaces of the common lines 2a and 2b are covered with an insulating member, i.e., a second insulating adhesive tape. With this, the loops of the bonding wires can be lowered, thereby achieving a thinner package.

Description

technical field [0001] The present invention relates to a semiconductor device and a method of manufacturing the semiconductor device. More particularly, the present invention relates to a semiconductor device having a common line providing electrical connection to those electrode pads handling common signals among a plurality of electrode pads on a semiconductor element and a method of manufacturing the semiconductor device. Background technique [0002] FIG. 6 is a schematic diagram showing an example of the prior art. This semiconductor device consists of a LOC (Lead On Chip) structure and is provided with an on-chip semiconductor element 1, a plurality of leads L and common lines 2a' and 2b' connected through insulating tape T on the semiconductor element 1.
