Objectifs du cours

Low cost and reliability are the main important factors for the successful commercialization of MEMs devices. It is possible to decrease the cost of the MEMs device by shifting from ceramic packages down to wafer to wafer bonded MEMs. On the other hand, the ability to maintain the suitable environmental conditions either vacuum or inert gas inside the package of MEMs devices like is the key for assuring high reliability to these MEMs devices. The pressure requirements of some MEMS hermetically packaged devices such as gyroscopes, resonators, IR bolometers, RF devices and optical mirrors are very stringent.

Due to the desorption phenomena of gaseous species from the internal surfaces, the vacuum inside a MEMS, after bonding encapsulation, tends to be degraded. Post process vacuum quality control and reliability for hermetic bonding is extremely important for overall device reliability and process yield. In this course we analyze the main factors that are critical in the vacuum design of hermetically sealed MEMS.

Comparisons evaluation of wafer level bonding techniques, gas sources, outgassing profiles of different materials used in MEMS as well as getter solutions are presented and discussed. We introduce a novel calculation model for vacuum sealed MEMS lifetime prediction. New analytical method based on single die MEMS residual gas analyses (RGA) is presented.

Public cible

The course is structured to be supportive to MEMS packaging engineers, MEMS bonding process engineers and generally to R&D personals that work in MEMS design activities.
