Problems solved by technology

[0013] However, we have found that since silicon nitride (Si 3 N 4 ) is relatively expensive and exposes the outside of the sealing member 80, so it is easy to be damaged by external impact
[0014] In addition, it is difficult to bond the insulating layer 96 to the electrodes 91, 92, 93, 94 using the thermal grease 60, and when the thermal grease 60 is not evenly applied, the thermal characteristics deteriorate rapidly

Abstract

A power module having dual-sided cooling is provided with a semiconductor chip between an upper board and a lower board of the power module. In particular, the upper board includes: a first bonding layer made of a dielectric material, and a first electrode made of a copper material and provided on a first surface of the first bonding layer, and the first electrode is connected to the semiconductorchip. The lower board includes: a second bonding layer made of a dielectric material, and a second electrode made of a copper material and provided on a first surface of the second bonding layer, andthe second electrode is connected to the semiconductor chip. More specifically, a thickness of the first electrode is greater than a thickness of the first bonding layer, and a thickness of the second electrode is greater than a thickness of the second bonding layer.

Description

technical field [0001] The present invention generally relates to power modules with double-sided cooling. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Generally, in order to operate a drive motor of a green car such as a hybrid car or an electric car, it is necessary to properly transmit current supplied from a high voltage battery to a power module of the drive motor. [0004] Such power modules generate considerable heat due to fast switching operations. Since such heat generation reduces the efficiency of the power module, a cooler for cooling the power module is provided. [0005] In a power module with double-sided cooling, boards are respectively mounted on both surfaces of semiconductor chips (ie, IGBTs or MOSFETs) of the power module, and coolers are mounted outside the boards, thereby simultaneously cooling both sides of the boards. ...
