Space solutions are similar to military & defense solutions, but add radiation effects
into the mix. For electronics to operate properly in space environments, they must
be radiation hardened. Radiation hardening can be performed through IC design, process
technologies like silicon-on-insulator (SOI) or elaborate system-level shielding.
Trusted Semiconductor Solutions offers rad-hard-by-design (RHBD), radiation hardended
technology (commercial semiconductor processes with radiation hardened libraries)
and radiation analysis and mitigation consulting services. We utilize space qualified
IC packaging and perform radiation testing and space qualification.
Rad-hard Electronic Design
Rad-hard integrated circuits are designed using rad-hard-by-design (RHBD) techniques
to maintain extremely low single event upset levels (1e-8 to 1e-12 upsets per bit-day
depending on application), no latch-up, high total dose, and neutron survivability.
Our expertise in SOI technology, radiation effects, and semiconductor physics allow
us to implement RHBD structures that minimize the area penalty and maximize the radiation
hardness of the circuits.
We qualifiy, screen and test space semiconductors per MIL-PRF-38535 and MIL-STD-883.
QCI testing to Class S, or Class V is performed using Group A, B, C, D and E tests
specified in the military standard. Group E radiation tests include neutron, total
dose (TID), transient, latch-up, and single event effect (SEE) tests.
Radiation testing of integrated circuits and electronic systems includes tests for
total ionizing dose (TID), prompt dose, dose rate, neutron, latch-up, and single
event effects (heavy ion & proton). Our ionizing radiation environments include:
Low Energy X-Ray, ARACOR-4100 X-Ray, Flash X-Ray, 1 MeV e-Accelerator, Cs-137 gamma
ray, and Co-60 gamma ray. In addition to performing the radiation tests, we also
develop hardness assurance test plans, create the custom test boards and fixtures
required for radiation testing, and thoroughly analyze and report test results.
Rad-Hard ASIC Libraries
Rad-hard ASIC libraries have been developed and are planned for leading-edge, on-shore
commercial foundries. A 90nm SOI rad-hard library is available today. A 45nm SOI
rad-hard library and 32nm SOI rad-hard library are planned.
Space Qualified IC Packaging
Trusted Semiconductor Solutions provides integrated circuit package development and
assembly for space flight semiconductors. We offer the latest ceramic, hermetic and
organic package technology, including column grid arrays (CCGA), flip chip bonding,
3D packaging, and multi-chip modules (MCMs).
