20100064779 | METHOD OF CHECKING THE HERMETICITY OF A CLOSED CAVITY OF A MICROMETRIC COMPONENT AND MICROMETRIC COMPONENT FOR THE IMPLEMENTATION OF THE SAME - In order to check the hermeticity of a closed cavity of at least one micrometric component, said component includes a structure made over or in one portion of a substrate, a cap fixed to one zone of the substrate to protect the structure, and an indicator element whose optical or electrical properties change in the presence of a reactive fluid. The indicator element may be a copper layer for an optical check or a palladium resistor for an electrical check. The micrometric component is placed in a container which is then hermetically closed. This container is filled with a reactive fluid under pressure, which is oxygen for the optical check and hydrogen for the electrical check. The component in the container is subjected to a reactive fluid pressure higher than 10 bars for a determined time period, and to thermal (T>100° C.) or optical (λ<500 nm) activation. After this time period, an optical or electrical check of the indicator element determines the hermeticity of said cavity. | 03-18-2010 |
