This paper presents a microgripper using an amplification mechanism coupled to an electrostatic linear motor. The gripper design, particularly the principle of the amplification mechanism based on the combination of ground-links and moving pin-joints, is explained. The linear motor is composed of scratch drive actuator inducing the use of electrostatic(More)
16MHz and 91MHz micromechanical resonators based on the Resonant Suspended-gate MOSFET (RSG-MOSFET) architecture are demonstrated. A fabrication process using a polysilicon sacrificial layer and an aluminum-silicon alloy (AlSi 1%) suspended-gate was developed. Static and dynamic electrical characteristics of the Clamped-Clamped beam (CC-beam) resonator have(More)
—A 14-MHz in-plane nanoelectromechanical resonator based on a resonant-suspended-gate (RSG) MOSFET principle and integrated in a front-end process is demonstrated. The devices are in-plane flexural vibration mode beams (L = 10 µm, w = 165 nm, and h = 400 nm) with 120-nm gaps. This letter details the design and process flow fabrication steps. Then, the(More)
The very significant growth of the wireless communication industry has spawned tremendous interest in the development of high performances radio frequencies (RF) components. Micro Electro Mechanical Systems (MEMS) are good candidates to allow reconfigurable RF functions such as filters, oscillators or antennas. This paper will focus on the MEMS(More)
The paper reports on in-plane nanometer scale resonators fabricated on 8 inch industrial tools, with a process based on the advanced CMOS Front End Silicon On Nothing Technology. The aim is to propose totally integrated time reference functions realized by small size NEMS resonators. The measurement setup , simulation and experimental results in the range(More)
This paper presents results concerning an electromechanical DC-contact shunt switch based on a patented totally free-flexible metal membrane combined with an associated low temperature surface micromachining fabrication process. The electrostatic actuation enables an average measured actuation voltage of 9.2V for a 5 mum out-of-plane membrane deflection.(More)
