    摘要: A trenched device wafer includes a device substrate layer having a top surface; a plurality of devices in the device substrate layer, and a trench in the top surface. The trench extends into the device substrate layer, and is located between a pair of adjacent devices of the plurality of devices. A method for forming a device die from a device wafer includes forming a trench in a top surface of the device wafer between two adjacent devices of the device wafer. The trench has a bottom surface located (a) at a first depth beneath the top surface and (b) at a first height above a wafer bottom surface. The method also includes, after forming the trench, decreasing a thickness of the device wafer, between the two adjacent devices, to a thickness less than the first height.
