Other efforts have demonstrated operation of SiC IC's at much lower (T < 350C) temperatures, or very brief (less than few hours) operation at T ? 500C. NASA's SiC integrated circuit is the first semiconductor integrated circuit (for ANY semiconductor material) ever reported to demonstrate prolonged stable electrical circuit operation at 500 C. NASA is at 5000 hours of 500 C electrical operation and still counting for one of their demonstration circuits. This "proof of principle" demonstration differential amplifier integrated circuit only had three resistors and two transistors. The NASA / ITC goal for the next generaton of SiC chips that are fabricated starting from scratch is to increase the transistor count at least 100-fold. The process of up-scaling the SiC integrated circuitry to much higher levels of integration (i.e., up-scaling to IC chips with thousands of transistors) should be straightforward from previously developed silicon and GaAs IC technology, so the belief is that this can occur pretty rapidly now that the thermal durability breakthrough has been made. In 2000 NASA used an Endevco silicon-based accelerometer as the benchmark to validate the NASA Glenn SiC high-g accelerometer. Tests showed the NASA device operated as well as the Endevco benchmark device, but at higher temperatures. This initial result led to discussions between Endevco and Glenn about licensing opportunities to acquire Glenn?s SiC pressure and accelerometer sensor fabrication and packaging technologies. A license to three patents was eventually signed. The ITC work is moving the technology into the realm of commercial viability for on engine SiC hardware.

Can you explain why, if this is the world's first SiC IC, Inprox are talking about simplifying the design? Does Endevco's existing deal with NASA not qualify as the the first SiC IC?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
