Abstract
A method of preparing a computer processor die includes determining a warpage shape of the computer processor die at a testing temperature. The method also includes selectively contouring a thickness of the computer processor die at a contouring temperature by physically removing material from a surface of the computer processor die such that the surface will be substantially flat at the testing temperature.
