The silicon micromachined inertial sensor that deploys your automotive airbags can't simply be dropped into your laptop for free-fall detection without some do-differentlys. The differences go well beyond the application spaces of medium/high g and low-g that automotive sockets sport. In fact, the automotive and consumer markets present conflicting fundamental demands. Building a bridge between them means giving reconsideration to design, test, space, quality, time-to-market, front- and back-end assembly - and price. Development, test, and burn-in during production are the three biggest cost contributors in inertial sensor qualification. In accordance with accepted practice, burn-in is removed from the consumer production flow. As for test, cost is further reduced by a judicious choice of parameters at which operational corners are tested. This is usually based on a vendor-customer agreed-upon list of critical parameters. The remaining electrical parameters are guaranteed by design, an approach justified by using enhanced characterizations with previously established very high parametric process capability values over extended qualification regimens. The high quality and reliability pedigree of automotive readily comes across. Time-to-market can be shortened and power consumption can be reduced also by tailoring or reusing automotive-based platform elements, building blocks, and packaging. The performance demands for consumer products are less stringent than those for automotive applications. Circuits can therefore be simpler, which helps reduce the die size and probe and final test time, and improve yield as well. The resulting consumer package is not only low-cost (e.g., plastic), but also smaller and thinner for portable products.
