Abstract:
The present invention relates to a thermal dissipating element of a chip to dissipate heat producing by operating the chip. The thermal dissipating element includes a top plate and a side plate, wherein the top plate curves and extends to be the side plate. The top plate includes a sink contacting with the chip.
Abstract:
A chip-packaging substrate. The substrate is capable of reducing damage during packaging, shrinking its connecting portions so that the length of any of the gap slots between the packaging portion and the frame portion of the substrate is increased. Furthermore, a dummy layer is provided to one surface of the frame portion to flush the surface on the frame portion with that of the packaging portion as much as possible.
Abstract:
A substrate used in a semiconductor device. The substrate includes a first wiring layer, a second wiring layer, and an interconnection-wiring layer. The first wiring layer includes a plurality of first pads while the second wiring layer includes a plurality of second pads. The interconnection-wiring layer is set between the first and second wiring layer. In this case, at least one of the second pads isn't electrically connected with anyone of the first pads, and other second pads that located adjacent to this second pad, which is not electrically connected with the first pads, electrically connect to the interconnection-wiring layer. Furthermore, this invention also discloses a semiconductor device including the substrate.
Abstract:
A flip chip package structure. The structure includes a substrate, an IC chip electrically connected to the substrate through a plurality of conductive bumps, encapsulant between the substrate and IC chip, and an electrically protective device. The substrate has interior wiring, a plurality of first contacts arranged at a predetermined pitch among each other on a surface, and a trace line area beyond the first contacts on the surface. The electrically protective device has a protruding part covering the IC chip, and an extending part extending over the surface of the substrate with a gap as large as 40 mil. The extending part further covers the trace line area, and connects to the surface of the substrate using a fixing material.
