A multilevel interconnect silicon carbide integrated circuit chip with co-fired ceramic package and circuit board recently developed at the NASA GRC Smart Sensors and Electronics Systems Branch for high temperature applications. High temperature silicon carbide electronics and compatible packaging technologies are elements of instrumentation for aerospace engine control and long term inner-solar planet explorations.
NASA Glenn technician Ariana Miller prepares an ultrahigh vacuum chamber used to test the materials used in silicon carbide based sensors and electronics that can operate at extremely high temperatures (500 degrees Celsius and higher) for applications such as sensor systems for aircraft engines and Venus exploration.

Phil Neudeck- Can Take the Heat When it comes to the heat of extreme environments like Venus, electronics can get fried within a few minutes of arrival. But NASA Researcher Phil Neudeck and his team have developed extremely durable silicon carbide semiconductor integrated circuits to survive those harsh conditions. After successfully testing the electronics in our high-pressure, high-temperature extreme environments chamber, there is now a path forward for Venus landers to survive and operate scientific experiments on the planet’s surface for longer durations.
A nickel alloy developed at the National Aeronautics and Space Administration (NASA) Lewis Research Center being poured in a shop inside the Technical Services Building. Materials technology is an important element in the successful development of both advanced airbreathing and rocket propulsion systems. An array of dependable materials is needed to build different types of engines for operation in diverse environments. NASA Lewis began investigating the characteristics of different materials shortly after World War II. In 1949 the materials research group was expanded into its own division. The Lewis researchers studied and tested materials in environments that simulated the environment in which they would operate. Lewis created two programs in the early 1960s to create materials for new airbreathing engines. One concentrated on high-temperature alloys and the other on cooling turbine blades. William Klopp, Peter Raffo, Lester Rubenstein, and Walter Witzke developed Tungsten RHC, the highest strength metal at temperatures over 3500⁰ F. The men received an IR-100 Award for their efforts. Similarly a cobalt-tungsten alloy was developed by the Fatigue and Alloys Research Branch. The result was a combination of high temperature strength and magnetic properties that were applicable for generator rotor application. John Freche invented and patented a nickel alloy while searching for high temperature metals for aerospace use. NASA agreed to a three-year deal which granted Union Carbide exclusive use of the new alloy before it became public property.
