Abstract:
A first embodiment is a method for semiconductor process control comprising clustering processing tools of a processing stage into a tool cluster based on processing data and forming a prediction model for processing a semiconductor wafer based on the tool cluster. A second embodiment is a method for semiconductor process control comprising providing cluster routes between first stage tool clusters and second stage tool clusters, assigning a comparative optimization ranking to each cluster route, and scheduling processing of wafers. The comparative optimization ranking identifies comparatively which cluster routes provide for high wafer processing uniformity. Further, wafers that require high wafer processing uniformity are scheduled to be processed along one cluster route that has a high comparative optimization ranking that identifies the one cluster route to have a highest wafer processing uniformity, and wafers that do not require high wafer processing uniformity are scheduled to be processed along another cluster route.
Abstract:
Semiconductor device design methods and conductive bump pattern enhancement methods are disclosed. In some embodiments, a method of designing a semiconductor device includes designing a conductive bump pattern design, and implementing a conductive bump pattern enhancement algorithm on the conductive bump pattern design to create an enhanced conductive bump pattern design. A routing pattern is designed based on the enhanced conductive bump pattern design. A design rule checking (DRC) procedure is performed on the routing pattern.

Abstract:
A bump structure for electrically coupling semiconductor components is provided. The bump structure includes a first bump on a first semiconductor component and a second bump on a second semiconductor component. The first bump has a first non-flat portion (e.g., a convex projection) and the second bump has a second non-flat portion (e.g., a concave recess). The bump structure also includes a solder joint formed between the first and second non-flat portions to electrically couple the semiconductor components.
