    MEMS processes for Quantum Computing and Quantum Sensing

    TechBlog / September 22, 2021

    Since 1994 Fraunhofer ISIT is one of the leading institutes in Europe for applied research in MEMS development and processing. Products like MEMS mirrors, loudspeakers, bio sensors and microfluidics have been manufactured in the ISIT cleanroom fab (2500 m², 8” / 200 mm silicon and crystalline quartz / amorphous glass wafers). Moreover, transistors and batteries for power electronics applications are being developed in our own facilities. Both MEMs and power electronics have been successfully transferred into prototypes and products.

  • Due to cost pressure and for reasons of climate technology, packaging technology is faced with the task of making manufacturing processes more cost-effective as well as more energy-saving and thus more climate-friendly. One answer to this challenge is the development and use of low-temperature solders, which can already be used in many areas such as the production of white goods (household appliances), consumer electronics, lighting with LED technology and many other applications. Due to the low ambient and operating temperatures of these electronic assemblies and systems, a low melting point solder alloy is suitable for manufacturing.

    In-situ X-ray analysis during the soldering process

    August 17, 2021

    Pores in solder joints are always an issue when it comes to electrical load capacity, heat dissipation and reliability of electronic assemblies. To demonstrate the formation of pores during a soldering process, we offer the possibility to observe a reflow soldering process in an X-ray facility directly on site. During this process, the melting process and the formation of pores in the solder can be monitored live. Our technology makes it possible to take X-ray videos and capture images at any point of the analysis. Find out now in our Techblog how exactly the innovative soldering process is carried out and finally evaluated.

    Surface acoustic wave sensors

    June 21, 2021

    Sensors based on the modulation of surface acoustic waves (SAW) can be used to measure various physical phenomena: In addition to mass absorption, elastic, viscoelastic or electrical effects can be exploited. Dedicated functional layers allow a wide range of applications with pressure, humidity, electric field, vibration, gas, bio or magnetic field sensors.
