難であるという問題があった。In this conventional TCP, since the product name and the manufacturing lot number are imprinted on the back surface of the semiconductor chip, the imprintable range is very narrow compared to other types of packages, and it is mounted. The size and number of characters that can be imprinted differ depending on the outer shape of the semiconductor chip. For example, in CMOS G / A, there are 20 to 30 types of outer shapes of semiconductor chips even with the same number of pins, and it is very difficult to manage the product outer shape and marking designation for each type.
