Methods of optimization of implant conditions to minimize channeling and structures formed thereby

摘要

Methods of forming a microelectronic structure are described. Those methods comprise implanting a first concentration of a species into an active area with a first energy, wherein the species pre-damages a portion of the active area, and then implanting a second concentration of the species into the active area with a second energy, wherein the total concentration of the species does not substantially penetrate an underlying channel region.
