Abstract
An example ceramic panel has a first surface and a second surface. The ceramic panel has a bond finger well on the first surface of the ceramic panel a scribe line well on the second surface of the ceramic panel. The ceramic panel also has a scribe line along the scribe line well.
Claims19
A device, comprising:
- a ceramic substrate having:
- a first surface;
- a second surface adjacent to the first surface;
- a third surface adjacent to the second surface, the third surface having a first roughness, the second surface and the third surface forming a notch;
- a fourth surface adjacent to the third surface, the fourth surface having a second roughness rougher than the first roughness;
- and
- a fifth surface adjacent to the fourth surface, the fifth surface having a third roughness rougher than the second roughness, wherein the second surface, the third surface, the fourth surface, and the fifth surface comprise at least a portion of an edge of the device.
