2. RADIATION

RADIATION• CHANGE DESIGN AND PROCESSES, BOTH

ARE VERY COSTLY IN THE ADVANCED TECHNOLOGIES.

• DESIGN FOR RADIATION TOLERANCE GIVES INCREASED COSTS FOR DESIGN TOOLS AND SOFTWARE.

• USAGE OF SHIELDING OR RAD PACKS ARE ALSO EXPENSIVE AND NOT VERY EFFICIENT AGAINST SOME TYPES OF RADIATION

3. RELIABILITY (FAILURE RATE)

RELIABILITY• NEW TECHNOLOGIES NOT INTENDED

FOR HIGH RELIABILITY SPACE MISSIONS

• DESIGN FOR LIMITED LIFE TIME ONLY

• TESTING LIMITED TO INTENDED APPLICATION

• NEW FAILURE MODES WITH NEW SUBMICRON TECHNOLOGIES

4. QML / TRB

XXIXXI

Defense Logistics AgencyDefense Logistics Agency Defense Supply Center ColumbusTaking the Lead in Land and Maritime Support

TRB Focus of Study• Qualification plans

– Pre determined– Individualized

• Process has reached targeted requirements • Review of historical data

– SPC– Commercial process– Life test– Screening Yields– TCI– Failure Analysis

XXIXXI

Defense Logistics AgencyDefense Logistics Agency Defense Supply Center ColumbusTaking the Lead in Land and Maritime Support

TRB Analysis of Data• Identification of test critical nodes,

– If critical to outcome, identify and control– Capability to assure low product defect rates– Control and understanding of assignable causes

• Long term Reliability : Unaffected or is improved• Process control

– Establish control limits at critical nodes• Knowledge of out of control conditions effect on reliability

– Establish relationship between field failures and test optimized

• Use of JEP-121 Guideline for MIL-STD-883 Screening & QCI Optimization

Conclusion

• Class S is Rules Oriented– Many requirements and restrictions– Don’t think, just do– Just follow the rules

• Class V is Results Oriented – Fewer requirements and restrictions– Think first then do

• Review the old requirements against current process• Produce high reliability space product without unnecessary costs• Study, discuss, coordinate, approve and document enhanced

5. COOPERATION

5. SUMMARY(1)Luckily, I have discovered superior radiation-

resistance of InP and solar cells. We have developed high-efficiency InP and GaAs-on-Si solar cells and performed a space flight demonstration.

(2)We have also developed a break-through technology (DH-structure tunnel junction) for multi-junction solar cells.

(3) Based on our research results, the NEDO R&D project for high-efficiency multi-junction solar cells for terrestrial application has been started in Japan.

5. SUMMARY-Continued(4) In that project, high-efficiency InGaP/GaAs 2-

junction and InGaP/InGaAs/Ge 3-junction cells with AM0 efficiencies of 26.9% and 29.2%, respectively, have been developed and their technologies have been transferred for space use.

(5) We have sown seeds for high-efficiency and low-cost multi-junction concentrator solar cells and modules, flexible and high-efficiency thin multi-junction cells, and radiation-resistant thin-film CuInGaSe cells for space applications.

(6) However, I really expect that results from R&D on materials, devices, components and systems for space use will be transferred to terrestrial use in the similar way with the Apollo Project in USA.

SOLUTIONS?• MANY SPACE APPLICATIONS WILL

6. FPGA

6-1 Issue Statement

JAXA has not obtained sufficient information on the folloeing items:(1)How this failure was first detected(2)Response from U.S. users including Tiger Team

to the ACTEL’s comments of the failure(3)Failure investigation activities by U.S. users

other than Tiger Team and NASA(4)Inherent structure defects with MEC die?

6-2 Objective

The delegation is to confirm information obtained during the period 2004 MAPLD conference andto obtain as much new information as possible.

6-3 Impact at JAXA and conclusion

Many rockets and sarellites projects use RTSX-S/SX-A series FPGA. If these devices have largefailure rate, many of the world’s space activities willbe affected and Japanese space program will besignificantly delayed.

It is serious problem!!

So we would like to discuss about the possiblefailure mode of those devices and exchangeinformation with each other to mitigate the risk.
