Venus has a corrosive, high-pressure (~100 bar), high-temperature (up to 500C) environment. The SiC-JFET technology and RS-485 link proposed complement Ozark IC's existing SiC-CMOS designs, including a general-purpose microprocessor and an integrated UV camera, that can be combined to create scientific instruments and housekeeping circuits that can operate at Venus surface temperature conditions.
The RS-485 data link standard is already a ubiquitous element in many applications: Oil Exploration - Deep well monitoring units can use the RS-485 to network sensors and actuators; Mil-Aero - Health monitoring of jet engines and turbines; Automotive - Health monitoring of internal combustion engines, exhaust systems, and emission controls; Industrial - Combustion and emission controls; Science - (Terrestrial) High temperature manufacturing processes","description":"NASA has demonstrated a resolve for a flagship mission in the coming years to revisit Venus and land instruments on the surface. Venus has a corrosive, high pressure (~100 bar), high-temperature (up to 500 C) environment presenting extreme design challenges for lander electronics. The ability to establish simple wire-line communications between circuits operating in extremely disparate temperature domains is a critical need. Different technologies have specific strengths (complexity, density, area, power) which span from high-performance, lower-temperature silicon to medium-density SiC-CMOS and lower-density, high-reliability SiC JFET-R. A viable lander design requires applying the right technology to each temperature domain. The premier IC process for ultra-high temperatures is the SiC JFET technology developed at NASA Glenn Research Center (GRC). In Phase I, Ozark IC proposes to use its extensive high temperature device and circuit expertise to create a PDK for the GRC SiC JFET process. Pre-existing designs by NASA will be recaptured with the PDK and simulation results will be validated against measured data. An RS-485 transceiver circuit will be designed using the PDK and verified such that it is ready for fabrication at the conclusion of Phase I.","startYear":2016,"startMonth":6,"endYear":2016,"endMonth":12,"statusDescription":"Completed","principalInvestigators":[{"contactId":195867,"canUserEdit":false,"firstName":"James","lastName":"Holmes","fullName":"James

The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
