Bonding Pad with Reduced Capacity

Mats I., Tarcenco V., Select Techno-Fix Ltd, CA

The technical solutions for the Integrated Circuits (ICs) packaging remains enough conservative during microelectronics development. The ICs with active components having size of micrometers or even nanometers continue to have bonding pads area within hundreds [...]

Fabry-Perot Diaphragm Fiber Optic Sensor (DFOS) for Acoustic Detection

Sun Y., Feng G., Georgiou G., Padron I., Niver E., Noe K., Chin K.K., New Jersey Institute of Technology, US

The diaphragm fiber optic sensor (DFOS) solely based on Fabry-Perot has been designed and fabricated with Micro-electric mechanical system(MEMS) technology. The DFOS utilizes a diaphragm as the sensing element to detect static and dynamic pressure [...]

MEMS Humidity Structure with Cantilever – Simulation of Behaviour

Suchanek P., Husak M., Czech Technical University in Prague, CZ

The aim of this paper is to report the design of the simple polymers structure humidity sensors and its mechanical and piezorezistive simulation in CoventorWare. Acquired simulation data gets a primary image about sizes bend [...]

Compact Electromagnetic XY Stage with Nano Scale Resolution and Vibration Resistance

Lee K-I., Kim S-H, Cho J-W, Choi Y.J., Shin J-K, Yoo J.C., Choi Y.J., Korea Electronics Technology Institute, KR

The design, fabrication, and the measurement results of an electromagnetic XY stage are presented. The device has an anti vibration structure and shows a high fill factor of 45% due to its unique structure. Furthermore, [...]

Simulation of ac-electroosmotic flows for concentration of particles on biosensors

Tanguy L., Casalis G., Nicu L., LAAS/CNRS, FR

Artificial concentration of particles in a fluid is a major challenge for micro- and nanobiosensors to enhance sensitivity and to reduce the time of response. We present here a numerical simulation of electroosmotic flows for [...]

On the stability length of fluid/liquid interfaces sustained by microfabricated pillars

Berthier J., Man Tran Van, Jeanson H., Sarrut N., CEA-LETI, FR

We focus here on the transfer and concentration of macromolecules from a flowing carrier fluid to a storage liquid. These liquids are flowing in parallel channels, separated by interfaces sustained by micro-pillars. The two fluids [...]

The Logical Elements “And”/ “Or” are Established on the Elements with Punch-Through and Deformation Space Charge Regions

Mats I., Diatex, Selected Texno-Fix, CA

In this article is proposal a design of logical elements “AND”/”OR” based on punch-through effect with a deformation (element ”AND”) of space charge regions (SCR). I.On the substrate N- type is formed P+ - bodies [...]

An Architecture of Quantum CPU

Téllez V., Campero A., Iuga C., Duchen G., Universidad Autónoma Metropolitana, MX

We present a quantum CPU (central processing unit) which is based on the quantum gate set. Using the Von Neuman model, the quantum CPU has development on a classical Digital Signal Processor (DSP TI6711). The [...]

Micro mixture: Size effect of micro mixing

Khelfaoui R., Benyoucef B., Colin S., ASSISTANT, DZ

A micro system is an optimized combination of elements fulfilling several complementary functions. Micro mixers applied in many fields, effective devices, for the handling of a chemical multitude of reaction, achieved objectives along ten years [...]

Characterization and Optimization Design of the Polymer-based Capacitive Micro-arrayed Ultrasonic Transducer

Chiou D.Y., Chen M.Y., Chang M.W., Deng T.M., RFID Technology Center/Industrial Technology Research Institute (RTC/ITRI), TW

The polymer-based capacitive micro-arrayed ultrasonic transducer (P-CMUT) have been shown to be a more attractive alternative to conventional CMUT in terms of “flexibility” that can be applied in many areas, ranging from consumer electronics to [...]
