Problems solved by technology

In such a conventional structure, the temperature may rise due to the thermal resistance of the spacer 7, and a space for wiring bonding connection is also required, so it is difficult for the semiconductor power module 200 to have a thinner thickness.

Abstract

A semiconductor sub-assembly and a semiconductor power module capable of having the reduced thickness of a chip and reduced thermal resistance are provided. The semiconductor sub-assembly includes a single or a plurality of semiconductor chips having a first electrode that is formed on the lower surface thereof, a second electrode that is formed on the upper surface thereof, and a plurality of chip-side signal electrode pads that are formed at one end of the upper surface thereof. The semiconductor chip is embedded in the embedded structure and a plurality of extension signal electrode pads are connected to each of the chip-side signal electrode pads. The extension signal electrode pad is formed on the embedded substrate in a size greater than the chip-side signal electrode pad when viewedon the plane.

Description

technical field [0001] The present invention relates to a semiconductor subassembly and a semiconductor power module, and more particularly, to a semiconductor subassembly capable of minimizing and reducing thermal resistance and a semiconductor power module having the semiconductor subassembly. Background technique [0002] The heat dissipation performance of semiconductor power modules is being improved, and furthermore, there is a trend to reduce mounted semiconductor chips. For example, in a dual-sided cooling package, equivalent cooling performance can be obtained with approximately half the size of a single-sided cooling package. In addition, in silicon carbide (SiC) power devices, which are examples of power semiconductors, it is expected that equivalent performance can be obtained with a chip that is 1 / 5 the size of a conventional chip. Meanwhile, in the double-sided cooling package, a connection structure with signal terminals becomes an obstacle to downsizing. As...
