Patent ID: 7459330

Claim:
A manufacturing method of an acceleration sensing device, comprising: providing a semiconductor substrate which has a principal surface including a plurality of device regions, wherein each of the device regions includes a movable sensing member and a plurality of internal electrodes, and wherein the internal electrodes are arranged around the movable sensing member; disposing a base substrate on a rear surface of the semiconductor substrate, wherein the rear surface is opposite to the principal surface of the semiconductor substrate; forming covering members over each of the device regions, so as to cover the movable sensing members; forming a plurality of interconnection films on each of the device regions so as to be coupled to the internal electrodes; forming a resin film on the principal surface of the semiconductor substrate so as to cover the covering member, the internal electrodes and a portion of each of the interconnection films in each of the device regions; and dividing the semiconductor substrate, the resin film and the base substrate, to separate the device regions into a plurality of acceleration sensing devices.
