Abstract: A method of manufacturing an integrated circuit device is provided. A first feature, which has a first susceptibility to damage by chemical mechanical processing (CMP), is formed at a first height as measured from an upper surface of the substrate. A second feature, which has a second susceptibility to damage by the CMP, is formed at a second height as measured from the upper surface of the substrate and is laterally spaced from the first feature by a recess. The second height is greater than the first height, and the second susceptibility is less than the first susceptibility. A sacrificial coating is formed in the recess over an uppermost surface of the first feature. CMP is performed to remove a first portion of the sacrificial coating and expose an upper surface of the second feature while leaving a second portion of the sacrificial coating in place over the first feature.

Abstract: A method for measuring an implant dosage distribution of a semiconductor sample is provided. The method includes generating a photomodulation effect in a three-dimensional structure of the semiconductor sample and measuring a reflection information of the three-dimensional structure. A geometry information of the three-dimensional structure of the semiconductor sample is obtained. The geometry information of the three-dimensional structure is converted into an estimated reflective data. The reflection information is compared with the estimated reflective data to determine the implant dosage distribution of the three-dimensional structure of the semiconductor sample.

Abstract: An IC device manufacturing process effectuates a planar recessing of material that initially varies in height across a substrate. The method includes forming a polymer coating, CMP to form a planar surface, then plasma etching to effectuate a planar recessing of the polymer coating. The material can be recessed together with the polymer coating, or subsequently with the recessed polymer coating providing a mask. Any of the material above a certain height is removed. Structures that are substantially below that certain height can be protected from contamination and left intact. The polymer can be a photoresist. The polymer can be provided with suitable adhesion and uniformity for the CMP process through a two-step baking process and by exhausting the baking chamber from below the substrate.
