Abstract
A vacuum suction apparatus includes a semiconductor substrate with a top portion having grooves and a bottom portion having through holes, wherein each said groove correspondingly connects with at least one said through hole, and the groove has a width greater than a width of the through hole; and a cover plate disposed on a top surface of the semiconductor substrate. At least one edge of the vacuum suction apparatus has a vacuum chamber, which connects with the grooves. In another embodiment, the cover plate is replaced with a vacuum cover disposed above the semiconductor substrate, wherein the vacuum cover and the semiconductor substrate construct a vacuum chamber.
