Abstract
The back side of a strip substrate with plural semiconductor chips mounted thereon is vacuum-chucked to a lower mold half of a mold, and in this state the plural semiconductor chips are sealed with resin simultaneously to form a seal member. Thereafter, the strip substrate and the seal member are released from the mold and are cut into plural semiconductor devices. The semiconductor devices thus obtained are improved in their mounting reliability.
