    • A process for producing a micromachine, in which the corrosion of structure can be inhibited; and a relevant micromachine. There is provided a process for producing a micromachine, characterized by including the step of conducting patterned formation of sacrificial layer (12) of a silicon oxide material containing hydrogen fluoride dissociation species on substrate (11); the second step of forming structure (16) on the substrate (11) so as to cover the sacrificial layer (12); the third step of making hole (18) through the structure (16) covering the sacrificial layer (12), the hole (18) reaching the sacrificial layer (12); and the fourth step of introducing either hydrogen fluoride gas only or hydrogen fluoride gas plus an inert gas only through the hole (18) to thereby etch the sacrificial layer (12) with the use of the dissociation species contained in the sacrificial layer (12) with the result that a vibration space is created between the substrate (11) and the structure (16). Further, there is provided a relevant micromachine.

    • PURPOSE: In the electrode structure of the piezo-electric resonator and piezo-electric resonator is the manufacturing process, by being proceed the thermal budget and sealing process the stress created in the frequency arbitration process is alleviated. CONSTITUTION: A piezoelectric(31) is vibrated with the electric signal. The first and second electrode structures(32a, 32b) are formed in each of the bottom surface and piezoelectric meaning top surface. The first and the second electrode structure have the laminating structure of being successive of the first layer to the fourth layer. The first layer and the third layer are formed into the alloy including Cr, the second level and fourth layer are formed into Ag or the alloy including Ag. The first layer and the third layer are formed into the Cr-Ni alloy.
