摘要:
A semiconductor chip includes flip chip contacts that are arranged on contact surfaces of an active top side of the semiconductor chip. The contact surfaces are surrounded by a passivation layer that covers the active top side while leaving exposed the contact surfaces. The passivation layer includes thickened portions that surround the contact surfaces. The semiconductor chip formed with thickened portions around the contact surfaces is protected from delamination during packaging of the semiconductor chip to form a semiconductor device.
摘要:
Improved structures for and methods for assembling heatspreader attachments in integrated circuit packages permit attachment of a relatively low cost heatspreader having a high coefficient of thermal expansion directly to the back of a die while maximizing thermal performance, mechanical integrity and reliability of the assembly. The improvements are realized through the use of specific adhesive materials to attach the heatspreader to the die, heatspreader geometries, adhesive geometries, assembly techniques and underfill geometries.
