摘要: This paper reports the design and fabrication of bulk mode micromechanical disc resonators operating in radial wine-glass modes excitation. The reported structures are fabricated utilizing a single crystal SOI wafer through micromachining processes. Both on device layer with thickness 20 µm gap size 1.75 between resonant beam surrounding electrodes. Four anchors support using T-shaped connection stem. designed resonate at 2.87 3.99 MHz, wine glass respectively, electrostatically actuated by DC voltage 110 V show high quality factors while air, 1,1876.2 for 7380 radial. In addition, used distributed point mass measurements sputtered gold metal layer. resonator shows frequency down shift 1 kHz 44 ngr mass, 22 83 µgr. Same test is performed resonance 1.24 25.54 was observed respectively air room temperature.
