METHOD OF FABRICATING BUMP STRUCTURE
摘要:
A method for fabricating bump structure forms an under-bump metallurgy (UBM) layer in an opening of an encapsulating layer, and then forms a bump layer on the UBM layer within the opening of the encapsulating layer. After removing excess material of the bump layer from the upper surface of the encapsulating layer, the encapsulating layer is removed till a top portion of the bump layer protrudes from the upper surface of the encapsulating layer.
