Abstract

Systems and methods for chemical mechanical planarization topography control via implants are disclosed. In one embodiment, a method of manufacturing a semiconductor device includes increasing the content of at least one of silicon or germanium in at least select regions of a dielectric material thereby reducing the material removal rate for a chemical mechanical polishing (CMP) process at the select regions, and removing material from the dielectric material using the CMP process. In another embodiment, a method of manufacturing a semiconductor device includes increasing content of at least one of boron, phosphorus, or hydrogen in at least select regions of a dielectric material thereby increasing the material removal rate of a CMP process at the select regions, and removing material from the dielectric material using the CMP process.
