Abstract
A device package method and structure thereof. The method includes steps of: providing a base and a cover, and placing a sensing device on the bottom of cavity base; placing sealant between the cover and edge part of the base, and then covering the cover on the base; irradiating a laser on the edge part for melting the sealant, so as to bond the cover and edge part; and enabling the sealed space formed between the cover and the cavity base to be in vacuum. Therefore, sensing element with high sensitivity can be packaged and manufactured efficiently.
