MEMSCAP (Paris:MEMS) (NYSE Euronext: MEMS), the leading provider of innovative solutions based on MEMS (micro-electro-mechanical systems) technology announces today the launch of a program of co-design for integrated circuits (ASIC) with the AXLR Technological Transfer Acceleration Company (SATT) and the Montpellier Laboratory of Computer Science, Robotics and Microelectronics (LIRMM) for piezoresistive pressure transducers mainly targeting the medical applications of dialysis and blood filtration. The collaboration between MEMSCAP, the SATT AXLR and the LIRMM aims at the implementation of research work carried out at LIRMM on intelligent signal conditioning of resistive sensors. Patents protecting this innovation filed by the CNRS and the University of Montpellier have been granted and have been licensed by MEMSCAP as part of this project. The total expected duration of the project is 18 months and includes the design, prototyping and validation of an integrated circuit specific to the needs of MEMSCAP's medical products and its integration into MEMSCAP products. The promising innovation of the LIRMM directly addresses the core technology of MEMSCAP aerospace and medical sensors which are based on piezoresistive effect. One of the functions of a hemodialysis machine is to measure and display arterial and venous pressures as well as to notify the operator when these pressures fluctuate outside of an established alarm limit. Arterial and venous pressure monitoring provides information regarding vascular access and the extracorporeal circuit in which a patient's blood is circulating. Correct interpretation of these pressures can: MEMSCAP transducers are currently designed in multiple hemodialysis equipments. Our transducers combine the required accuracy, long-term stability, and sustain most of the aggressive sterilization processes performed in these equipments and medical procedures. Implementation of the LIRMM technology would help provide sensors that significantly reduce the operational and recurring maintenance and calibration costs of dialysis and filtration machines. This project extends the partnership between LIRMM and MEMSCAP which, was initiated during the fourth quarter of 2016, within a 36-months EUROSTARS project funded by the French and Norwegian authorities to adapt this signal conditioning technology to the aerospace applications of Full Authority Digital Engine Control (FADEC) and Air Data, Attitude and Heading Reference Systems (ADHARS).

Microelectrode arrays (MEAs) offer a powerful tool to both record activity and deliver electrical microstimulations to neural networks either in vitro or in vivo. Microelectronics microfabrication technologies now allow building high-density MEAs containing several hundreds of microelectrodes. However, dense arrays of 3D micro-needle electrodes, providing closer contact with the neural tissue than planar electrodes, are not achievable using conventional isotropic etching processes. Moreover, increasing the number of electrodes using conventional electronics is difficult to achieve into compact devices addressing all channels independently for simultaneous recording and stimulation. Here, we present a full modular and versatile 256-channel MEA system based on integrated electronics. First, transparent high-density arrays of 3D-shaped microelectrodes were realized by deep reactive ion etching techniques of a silicon substrate reported on glass. This approach allowed achieving high electrode aspect ratios, and different shapes of tip electrodes. Next, we developed a dedicated analog 64-channel Application Specific Integrated Circuit (ASIC) including one amplification stage and one current generator per channel, and analog output multiplexing. A full modular system, called BIOMEA™, has been designed, allowing connecting different types of MEAs (64, 128, or 256 electrodes) to different numbers of ASICs for simultaneous recording and/or stimulation on all channels. Finally, this system has been validated experimentally by recording and electrically eliciting low-amplitude spontaneous rhythmic activity (both LFPs and spikes) in the developing mouse CNS. The availability of high-density MEA systems with integrated electronics will offer new possibilities for both in vitro and in vivo studies of large neural networks. © 2010 Elsevier B.V.

The DRS Tamarisk® 320 camera, introduced in 2011, is a low cost commercial camera based on the 17 μm pixel pitch 320x240 VOx microbolometer technology. A higher resolution 17 μm pixel pitch 640x480 Tamarisk® 640 has also been developed and is now in production serving the commercial markets. Recently, under the DARPA sponsored Low Cost Thermal Imager-Manufacturing (LCTI-M) program and internal project, DRS is leading a team of industrial experts from FiveFocal, RTI International and MEMSCAP to develop a small form factor uncooled infrared camera for the military and commercial markets. The objective of the DARPA LCTI-M program is to develop a low SWaP camera (<3.5 cm3 in volume and <500 mW in power consumption) that costs less than US $500 based on a 10,000 units per month production rate. To meet this challenge, DRS is developing several innovative technologies including a small pixel pitch 640x512 VOx uncooled detector, an advanced digital ROIC and low power miniature camera electronics. In addition, DRS and its partners are developing innovative manufacturing processes to reduce production cycle time and costs including wafer scale optic and vacuum packaging manufacturing and a 3-dimensional integrated camera assembly. This paper provides an overview of the DRS Tamarisk® project and LCTI-M related uncooled technology development activities. Highlights of recent progress and challenges will also be discussed. It should be noted that BAE Systems and Raytheon Vision Systems are also participants of the DARPA LCTI-M program. © 2013 SPIE.

A wireless sensor network is proposed for monitoring buildings to assess earthquake damage. The sensor nodes use custom-developed capacitive microelectromechanical systems strain and 3-D acceleration sensors and a low power readout application-specified integrated circuit for a battery life of up to 12 years. The strain sensors are mounted at the base of the building to measure the settlement and plastic hinge activation of the building after an earthquake. They measure periodically or on-demand from the base station. The accelerometers are mounted at every floor of the building to measure the seismic response of the building during an earthquake. They record during an earthquake event using a combination of the local acceleration data and remote triggering from the base station based on the acceleration data from multiple sensors across the building. A low power network architecture was implemented over an 802.15.4 MAC in the 900-MHz band. A custom patch antenna was designed in this frequency band to obtain robust links in real-world conditions. The modules have been validated in a full-scale laboratory setup with simulated earthquakes. © 2012 IEEE.

2011 16th International Solid-State Sensors, Actuators and Microsystems Conference, TRANSDUCERS'11 | Year: 2011
An Ultra-Low-Power readout architecture for capacitive MEMS-based accelerometers and strain sensors is presented. The system can read both accelerometers and strain sensors in a half-bridge configuration. The gain is controlled by integrating pulses from the excitation voltage allowing accurate control of the Signal-to-Noise ratio. A Figure-of-Merit of 4.41×10 20 F√(W/Hz) was achieved for a sensor range of ±2.0g and ±20,000 με over a 100Hz bandwidth. Residual motion artifacts are also cancelled by the system. © 2011 IEEE.

Proceedings - Electronic Components and Technology Conference | Year: 2010
The fabrication of through-silicon vias (TSVs) is a major component in the development of three-dimensional (3D) integration technology and advanced 3D packaging approaches. The large diameter and length of TSVs, as compared to traditional interconnects, create some unique process challenges. Via plating and chemical-mechanical polishing (CMP) processes used in standard copper interconnect technology are generally not suitable for TSV fabrication. Therefore, efforts are being made to develop such processes specifically for TSV technology. This paper will describe the development of a void-free Cu electroplating process for TSV filling, along with CMP processing to remove the overburden layer and expose the Cu-filled vias for subsequent metallization. The focus of the paper will be the integration of the TSV plating and CMP processes, with discussion regarding observed integration challenges and their solutions. First, a Cu electroplating process was developed for defect-free, bottom-up filling of silicon vias from 20-200μm in diameter and 150-375μm deep, with aspect ratios from 1:1 to 8:1. Next, CMP tests were conducted using Cu-filled silicon vias of 50μm diameter and 150μm depth, designed for use in a MEMS wafer-level packaging application. These tests indicated that plating nonuniformity and Cu mound defects over filled vias caused significant CMP process issues. The plating process was then modified to eliminate these problems in the Cu films, resulting in improved CMP uniformity and reduced polishing time. ©2010 IEEE.
