    摘要: Deep trenches formed beneath contact level in a semiconductor substrate function as crackstops, in a die area or in a scribe area of the wafer, and may be disposed in rows of increasing distance from a device which they are intended to protect, and may be located under a lattice work crackstop structure in an interconnect stack layer. The deep trenches may remain unfilled, or may be filled with a dielectric material or conductor. The deep trenches may have a depth into the substrate of approximately 1 micron to 100 microns, and a width of approximately 10 nm to 10 microns.

    摘要: A method of selectively altering material properties of a substrate in one region while making a different alteration of material properties in an adjoining region is provided. The method includes selectively masking a first portion of the substrate during a first exposure and selectively masking a second portion of the substrate during a second exposure. Additionally, a mask may be formed having more than one thickness where each thickness will selectively reduce the amount of energy from a blanket exposure of the substrate thereby allowing a substrate to receive different levels of energy dosage in a single blanket exposure.
