Abstract:
A chip scale surface-mountable packaging method for electronic and micro-electro mechanical system (MEMS) devices, comprising:(a) forming an interconnection and sealing pattern as a trench in one surface of a conductive cover substrate using semiconductor fabricating and micromachining techniques; (b) filling the trench as the pattern of the cover substrate with an insulating material selected from the group consisting of glass and ceramic, and planarizing the surface of the cover substrate having the insulating material to form a bonding pattern; (c) aligning the cover substrate with a device substrate, in which electronic or MEMS devices are integrated, and bonding the cover substrate and the device substrate; and (d) polishing the other surface of the cover substrate and forming an electrode pattern thereon.
