Abstract
In described examples, a bondline structure is arranged along a periphery of a cavity. The bondline structure extends from a first substrate and is configured to bond with an interposer arranged on a second substrate. A diffusion barrier is arranged on the first substrate for contacting the interposer. The diffusion barrier is arranged to impede a contaminant against migrating from the bondline structure and entering the cavity.
