Abstract
Edge passivation for a small area silicon cell is provided in a batch process by providing streets between individual cells formed in a silicon substrate and diffusing dopant through the substrate along the streets. Following completion of fabrication of the plurality of cells in the substrate, the substrate is sawed along the streets with the diffused region providing passivation along the edges of the individual die.
