Abstract

An apparatus that comprises a device on a substrate and a crack stop in the substrate. Methods of forming a device are also disclosed. The methods may include providing a device, such as a semiconductor device, on a substrate having a first thickness, reducing the thickness of the substrate to a second thickness, and providing a crack stop in the substrate. Reducing the thickness of the substrate may include mounting the substrate to a carrier substrate for support and then removing the carrier substrate. The crack stop may prevent a crack from reaching the device.
