Abstract

A method of manufacturing a semiconductor device includes providing a matrix frame which includes a plurality of die pads, mounting a semiconductor chip on the respective die pads, and sealing the semiconductor chip in blocks. After the semiconductor chip is sealed by the sealing resin, inner leads which are extended from the sealing resin are punched by a punching blade. Then, the block is diced to individual semiconductor devices by a rotary blade.
