Abstract

Methods and processes for establishing a rework threshold for layers applied after thermal processing during fabrication of semiconductor devices are provided. One method includes, for instance: obtaining a device after at least one laser annealing process is completed, the device including a substrate surface and at least one layer over the substrate surface; performing lithography on the at least one layer; positioning a first contact-to-gate layer over the at least one layer; checking alignment of electrical connections between the substrate surface and the first contact-to-gate layer; determining if an overlay error is present; and adjusting at least one subsequent fabrication process pursuant to the overlay error.
