IC LEVEL ESD SOLUTION

Semisolution is providing the US patented non-snap back type ESD protection IP and ESD protection design service and consulting. The ESD protection solution of GTL is fundamentally different from the existing ESD I/O protection and is providing a solution to effectively apply the total power domain inside the IC core to ESD from the IC design stage.
Only the specialized advantages of the GTL's ESD solution are easily applicable due to its compatibility with the foundry and the process and early checking of the ESD characteristics without manufacturing the IC through prior simulation are possible.

More aggressive processes, rules and designs cause ESD failure mechanisms that were not observed previously.
I/O ESD protection by foundry and I/O library vendors usually over-protects I/O, and allows core circuit failure.
There is no one ESD protection scheme or device that can protect all circuit from ESD damage
(no one-size-fits-all remedy !!)

In-depth coverage on complete spectrum of chip making
	- GTLeader's expertise covers complete spectrum of chip making; processes, modeling, simulution, reliability, circuit design, packaging, etc. - GTLeader's ESD experts have fixed more than 300 designs from 0.35um to 0.13um technology node. - GTLeader has a whole chip level ESD protection solution as well as special and high speed I/O protection cells
Design review
	- GTLeader will review your design before tape-out to improve ESD performance. - GTLeader will provide ESD design rules and a super set of TSMC ESD design rules,coverign core circuit protection schemes as well as I/O - TLP test service for design and debugging
TLP Testing
	- GTLeader provides TLP testing for FA and design verification.

Device simulators like Medici(Pisces), Davinci, etc., have been used almost 20years to simulate a vaiety of effects, including latch-up and ESD. They are quite complicated to use, but provide good physics, including geometry effects. However, device simulators have their own set of problems, such as, run out of grid nodes quickly and 3D simulators are too slow.
Circuit simulators like Spice have been used, but not as successfully because they cannot deal very well with geometrical effects, and especially temperature coupling.

GTLeader in alliance with Sequoia Design Systems can provide accurate ESD/LU simulation to provide much
greater understanding of what is happening in the devices and circuits during failure. This insight is almost
impossible to obtain from experimental data alone.
GTLeader sratt have used simulation to predict failur mechanisms from 3um down to 90nm technologies.

Long testing due to ever increasing chip size, and repeated zapping to the same pin cause serious testing artifacts.
Current JEDEC spec and testing methodologies were developed some time ago. ESD testing labs interprete the JEDEC spec in their own way

ESD/LU testing without "side effects"
	- GTLeader provider optimized pin reduction method based on I/O ESD protection and power rail protection scheme analysis - Split test method to avoid charging/cumulative stres effects
Resident expertise on all required testing standards
