Abstract:
1. A method for producing piezoelectric vibrators, comprising: (a) defining a plurality of first substrates on a first wafer and a plurality of second substrates on a second wafer; (b) forming a pair of holes in at least some of the first substrates on the first wafer; (c) placing a conductive rivet in at least some of the holes; (d) press-fusing the conductive rivets in the first wafer to hermetically close the holes; (e) hermetically bonding the first and second wafers such that at least some of the first substrates substantially coincide respectively with at least some of the corresponding second substrates, wherein a piezoelectric vibrating strip is secured in a respective pairs of at least some of coinciding first and second substrates; and (f) cutting off at least some of the hermetically bonded pairs of first and second substrates from the first and second wafers.
