Abstract
Abstract A spherical shaped semiconductor integrated circuit ("ball") and a system and method for manufacturing same. The ball replaces the function of the flat, conventional chip. The physical dimensions of the ball allow it to adapt to many different manufacturing processes which otherwise could not be used. Furthermore, the assembly and mounting of the ball may facilitates efficient use of the semiconductor as well as circuit board space.
