Abstract
A method for fabricating semiconductor components includes the steps of providing a semiconductor substrate having a circuit side, a back side and integrated circuits and circuitry on the circuit side; thinning the substrate from the back side to a selected thickness to form a thinned substrate; applying a dopant to the back side of the thinned substrate; and laser processing the back side of the thinned substrate to form a plurality of patterns of lasered features containing the dopant. The dopant can be selected to modify properties of the semiconductor substrate such as carrier properties, gettering properties, mechanical properties or visual properties.
