Abstract

A semiconductor device has a sacrificial substrate and an electrical component disposed over the sacrificial substrate. A bump stop layer is formed within the sacrificial substrate. At least a portion of the bump or terminal of the electrical component is embedded into the sacrificial substrate to contact the bump stop layer. An encapsulant is deposited over the electrical component and sacrificial substrate. A channel is formed through the encapsulant and partially into the sacrificial substrate. The sacrificial substrate is removed to leave a bump or terminal of the electrical component extending out from the encapsulant. A thickness of the semiconductor device is determined by a thickness of the encapsulant and bump extending out from the encapsulant. A portion of the encapsulant can be removed to reduce the thickness of the semiconductor device. A conductive paste can be deposited over the bump or terminal extending out from the encapsulant.
