Abstract
A resized wafer using a negative photoresist ring, methods of manufacture and design structures thereof are disclosed. The method includes forming a ring within a radius of a wafer. The method also includes patterning a photoresist formed on the wafer, by exposing the photoresist to energy. Additionally, the method includes forming troughs in a substrate of the wafer based on the patterning of the photoresist, wherein the ring blocks formation of the troughs underneath the ring. The method also includes filling the troughs with a metal and resizing the wafer at an area of the ring.
