Abstract

Official abstract text for this publication.

A bonding chuck is discussed with methods of using the bonding chuck and tools including the bonding chuck. A method includes loading a first wafer on first surface of a first bonding chuck, loading a second wafer on a second bonding chuck, and bonding the first wafer to the second wafer. The first surface is defined at least in part by a first portion of a first spherical surface and a second portion of a second spherical surface. The first spherical surface has a first radius, and the second spherical surface has a second radius. The first radius is less than the second radius.
