Abstract:
1. A micro-electro-mechanical device, comprising: a device substrate including a device structure; a cap substrate defining a device cavity overlying the device structure; a bonding structure connecting the device substrate and the cap substrate, wherein the bonding structure circumvents the device structure; a flow containment micro-levee (FCML) formed on a first substrate, wherein the first substrate is selected from the device substrate and the cap substrate, wherein the FCML comprises an elongated ridge overlying a first surface of the first substrate, the FCML extending substantially parallel to the bonding structure; and a flow containment micro-cavity (FCMC) formed in a second substrate, wherein the second substrate is selected from the device substrate and the cap substrate, wherein the FCMC comprises an elongated channel formed in a first surface of the second substrate, the FCMC extending substantially parallel to the bonding structure; wherein the FCML circumvents the bonding structure.
