Appeal No. 96-1508 Application No. 08/112,445 This is a decision on appeal from the final rejection of claims 27 through 50, all of the claims pending in the application. The invention is directed to a guard wall for reducing delamination effects in a semiconductor die. Representative independent claim 27 is reproduced as follows: 27. A semiconductor die comprising: a semiconductor substrate; an electrically active region on the substrate; a patterned dielectric layer over the substrate and the electrically active region; and a guard wall extending through the dielectric layer, the guard wall lying adjacent to the electrically active region, the guard wall disposed in a guard wall opening in the dielectric layer, the guard wall opening having a main section and a plurality of cross sections, the guard wall including at least one sidewall spacer along the main section of the guard wall opening and a filling material.
