ACME’s New Microgravity SiC Devices Outperform Traditional Premium Grade Devices in Initial Testing
Albuquerque, NM (PRWEB) September 01, 2015 -- ACME Advanced Materials, Inc. today announced they have partnered with two of the world’s leading SiC research groups to independently evaluate and assess the performance enhancement from devices fabricated on their microgravity processed SiC substrates (S Grade). When compared to devices made on traditional Prime Grade substrates, ACME’s initial tests showed that the S Grade devices had
• Improved electronic transport
• Lower on-resistance
• Reduced forward voltage
• Higher current density threshold
• Increased reliability
In order to provide independent verification of these results and develop a deeper understanding of the microgravity process itself, ACME has partnered with Dr. Debbie G. Senesky who runs the EXtreme Environment Microsystems Laboratory (XLab) at Stanford University and Dr. Michael Dudley, Chairman of the Dept. of Materials Science & Engineering at Stony Brook University. Dr. Senesky’s group has been working with ACME since Jan 2015 to analyze S Grade substrate material properties and build Schottky diode test devices on S Grade substrates. Dr Dudley joined the team in July and his group will bring additional evaluation tools and expertise to the analysis.
“We’re really excited about partnering with such well-respected and talented groups to provide new insights and independent analysis of our results,” said ACME’s President & CEO Rich Glover, “The typical reaction we get from industry when they see our results is, ‘No way, this can’t be true.’ So, we decided to partner with experts that are well known in the Power Electronics Field and let them perform their own independent analysis.” The initial, first generation device improvements using ACME S grade SiC material will include:
• Superior MOSFET, transistor & diode avalanche energy clamping capability
• Vastly improved device in-rush current carrying capacity
• Faster allowable switching dV/dt for converters
• Improved short circuit survivability
“We’ve conducted detailed preflight and post flight analysis on these substrates and observe compelling modifications to the material structure,” said Dr. Senesky, “The devices we’ve built on S Grade substrates also show improved electrical performance when compared to devices built on traditional, unprocessed substrates. My team is digging into these results and we plan to start publishing and sharing the results soon.” Dr. Senesky added, “These results are quite intriguing and we’re looking forward to working with Dr. Dudley and applying his unique expertise in SiC microstructure to perform additional analysis.”
According to Dr. Dudley, “These results are really quite interesting and I’m looking forward to working with ACME and Dr. Senesky to evaluate and assess this S Grade material.”

About Stanford’s EXtreme Environment Microsystems Laboratory (XLab)
The XLab is a part of the Aeronautics and Astronautics Department at Stanford University and is focused on the development of micro- and nano-systems for operation within extreme harsh environments. Researchers are investigating the synthesis of temperature tolerant, chemically resistant and radiation-hardened wide bandgap semiconductor (SiC and GaN) thin films and nanostructures, which will serve as a platform for new sensor, actuator and electronic components that can operate and collect data under the most hostile conditions. XLab research supports a variety of applications including deep space systems, hypersonic aircrafts, combustion monitoring and subsurface monitoring.
