    摘要: Structures and methods for forming the same. A semiconductor chip includes a semiconductor substrate and a transistor on the semiconductor substrate. The chip further includes N interconnect layers on top of the semiconductor substrate and being electrically coupled to the transistor, N being a positive integer. The chip further includes a first dielectric layer on top of the N interconnect layers, and a second dielectric layer on top of the first dielectric layer. The second dielectric layer is in direct physical contact with each interconnect layer of the N interconnect layers. The chip further includes an underfill layer on top of the second dielectric layer. The second dielectric layer is sandwiched between the first dielectric layer and the underfill layer. The chip further includes a laminate substrate on top of the underfill layer. The underfill layer is sandwiched between the second dielectric layer and the laminate substrate.

    摘要: The present invention relates to a method for minimizing breakage of wafers during or after a wafer thinning process. A method of forming a rounded edge to the portion of a wafer remaining after surface grinding process is provided. The method comprises providing a semiconductor wafer having an edge and forming a recess in the edge of the wafer using any suitable mechanical or chemical process. The method further comprises forming a substantially continuous curved shape for at least the edge of the wafer located above the recess. Advantageously, the shape of the wafer is formed prior to the backside grind process to prevent problems caused by the otherwise presence of a sharp edge during the backside grind process.
