Beschreibung
Zusammenfassung:	A transducer includes a first substrate and an integrated circuit coupled to the first substrate. A sensor is electrically coupled to the integrated circuit and includes a second substrate having a first surface and a second surface opposite the first surface. The second substrate has scribe boundaries defining an outer edge of the second substrate and a chamber extending from the first surface towards but not reaching the second surface. A chamber extends from the second surface to meet the chamber from first surface. Scribe trenches in the second surface at the scribe boundaries have a width from the scribe boundary towards the chamber extending from the second surface. A membrane extends over the first surface and over the chamber extending from first surface. A plate extends from the first surface of the second substrate over the membrane.
