Abstract: 本明細書は、半導体素子が樹脂でモールドされており、その半導体素子がモールド表面に露出するリードフレームと接合されている半導体装置に関する。本明細書は、疲労劣化が進んで接合材にクラックが生じても、クラックが半導体素子に与える影響を低減することのできる技術を提供する。半導体装置2は、トランジスタ3と、リードフレーム8a、8bと、一方の面において第1接合材5によってトランジスタ3と接合されているとともに、他方の面において第2接合材6によってリードフレーム8bと接合されている金属スペーサ4と、樹脂モールド体13を備える。樹脂モールド体13は、トランジスタ3と金属スペーサ4を封止している。リードフレーム8a、8bの一面が樹脂モールド体13に密着している。第2接合材6には、その強度が第1接合材5の強度よりも低い材料が選定される。

Abstract: A method for bonding an LED assembly (71) or other electronic package (31) to a substrate PCB containing a heat-sink (52), which utilizes layers of reactive multilayer foil (51) disposed between contacts (32, 34) of the electronic package 31 and the associated contact pads (55) on the supporting substrate PCB. By initiating an exothermic reaction in the reactive multilayer foil (51), together with an application of pressure, sufficient heat is generated between the contacts (32, 34) and the associated contact pads (55) to melt adjacent bonding material (54) to obtain good electrically and thermally conductive bonds between the contacts 32, 34 and contact pads (55) without thermally damaging the electronic package (31), heat-sensitive components (35) associated with the electronic package (31), or other the supporting substrate PCB.
