PHYSICAL DESIGN
Using three layers of metal interconnect, Aeroflex UTMC
achieves optimized layouts that maximize speed of critical nets,
overall chip performance, and design density up to 600,000
equivalent gates.
Test Capability
Aeroflex UTMC supports all phases of test development from
test stimulus generation through high-speed production test. This
support includes ATPG, fault simulation, and fault grading. Scan
design options are available on all UT0.6µCRH/SRH storage
elements. Automatic test program development capabilities handle large vector sets for use with Aeroflex UTMC’s LTX/
Trillium MicroMasters, supporting high-speed testing (up to
80MHz with pin multiplexing).
Unparalleled Quality and Reliability
Aeroflex UTMC is dedicated to meeting the stringent performance requirements of aerospace and defense systems suppliers.
Aeroflex UTMC maintains the highest level of quality and reliability through our Quality Management Program under MILPRF-38535 and ISO-9001. In 1988, we were the first gate array
manufacturer to achieve QPL certification and qualification of
our technology families. Our product assurance program has kept
pace with the demands of certification and qualification.
Our quality management plan includes the following activities
and initiatives.
• Quality improvement plan
• Failure analysis program
• SPC plan
• Corrective action plan
• Change control program
• Standard Evaluation Circuit (SEC) and Technology Charac-
terization Vehicle (TCV) assessment program
• Certification and qualification program
Because of numerous product variations permitted with customer
specific designs, much of the reliability testing is performed using a Standard Evaluation Circuit (SEC) and Technology
Characterization Vehicle (TCV). The TCV utilizes test structures
to evaluate hot carrier aging, electromigration, and time dependent test samples for reliability testing. Data from the wafer-level
testing can provide rapid feedback to the fabrication process, as
well as establish the reliability performance of the product before
it is packaged and shipped.
Radiation Tolerance
Aeroflex UTMC incorporates radiation-tolerance techniques in
process design, design rules, array design, power distribution,
and library element design. All key radiation-tolerance process
parameters are controlled and monitored using statistical methods and in-line testing.
Notes:
1. Total dose Co-60 testing is in accordance with MIL-STD-883,
Method 1019. Data sheet electrical characteristics guaranteed to 1.0E5
rads(Si O2). All post-radiation values measured at 25°C.
2. Total dose Co-60 testing is in accordance with MIL-STD-883,
Method 1019 at dose rates <1 rad(SiO2)/s.
3. Short pulse 20ns FWHM (full width, half maximum).
4. Is design dependent; SEU limit based on standard evaluation circuit at 4.5V
worst case condition.
5. SEU-hard flip-flop cell. Non-hard flip-flop typical is 4E-8.
