Abstract

PURPOSE:To make it possible to adjust a frequency easily by making a hole in a substrate, packaging quartz, at the opposite position to an electrode of the quartz. CONSTITUTION:Quartz oscillator piece 2 is equipped at a prescribed position on IC substrate 5 together with other parts 6. In substrate 5, small hole 5 is made at the opposite position to an electrode of quartz. To adjust the frequency, metal is vapordeposited through mask hole 1'' in mask surface 1 and hole 5 in the electrode. In this case, mask 1 may roughly be positioned. The metal sticks only the required part of electrode 3 accurately via hole 5. Therefore, even if mask 1 shifts in position slightly, it sticks to the reverse side of substrate 5 and never sticks to an IC circuit.
