Abstract: PROBLEM TO BE SOLVED: To provide a new semiconductor chip carrier connection which has a chip carrier and a 2nd level assembly formed by a surface amount technology. SOLUTION: The surface mount technology for a ball grid array(BGA), a column grid array(CGA), etc., is adopted and basically includes a non-solder metal connection such as a copper connection. This invention is concerned with a column grid array structure and its process.
