5-10 GHz AlN Contour-Mode Nanoelectromechanical Resonators

Abstract: This paper reports on the design and experimental verification of Super High Frequency (SHF) laterally vibrating NanoElctroMechanical (NEMS) resonators. For the first time, AlN piezoelectric nanoresonators with multiple frequencies of operation ranging between 5 and 10 GHz have been fabricated on the same chip and attained the highest f-Q product (4.6E12 Hz) ever reported in AlN contour-mode devices. These piezoelectric NEMS resonators are the first of their class to demonstrate on-chip sensing and actuation o… Show more

“…[9][10][11][12] Out of these two materials, AlN stands out for its high dielectric strength, ease of deposition, and processing ͑involving low temperatures and nontoxic precursors͒, and its potential for integration with CMOS devices. AlN has previously been used for the fabrication of MEMS contour mode filters, 13 film bulk-wave acoustic resonator ͑FBAR͒ filters 14 ͑AlN being the material of choice for commercial FBAR production͒, high frequency resonators, 15 and switches. 9,10 Scaling of piezoelectric transduction to the nanoscale has failed in the past because of degradation of piezoelectric properties due to limited orientation in thin films and increases in internal stresses ͑cracking and excessive deformations in released structures͒.…”

“…Another type of resonator, the contour mode resonator (CMR), is becoming an important area of research, achieving more and more attention. The resonant frequency of CMR can be achieved as high as 10 GHz [3]. In addition, the Lamb wave resonators play an important role in MEMS resonators.…”

“…1). The resonance frequency of the proposed device is determined by the pitch, W 0 , of the finger electrodes forming the interdigital transducer (IDT) (Figure 2 (a)), and the material properties: equivalent Young's Modulus E eq and density ρ eq , by (1) [6]. When the sensor is exposed to an external magnetic field, the equivalent Young's Modulus of the overall structure is changed due to the magnetostrictive effect [4] of the magnetic material, resulting in a shift of the device resonance frequency.…”
