Abstract: A method for improving semiconductor yield by in-line repair of defects during manufacturing comprises inspecting dies on a wafer after a selected layer is formed on the dies, identifying defects in each of the dies, classifying the identified defects as killer or non-critical, for each killer defect determining an action to correct the defect, repairing the defect and returning the wafer to a next process step. Also disclosed is a method for determining an efficient repair process by dividing the die into a grid and using analysis of the grid to find a least invasive repair.

Abstract: A method for improving throughput in a semiconductor wafer deposition process in a high density plasma chamber includes processing a first wafer in the high density plasma chamber using a process that includes high power sufficient to burn fluorosilicate glass residue in the chamber. The method further includes removing the first wafer and processing additional wafers using the same process without cleaning the chamber between wafers.
