This paper describes a 2-D atomic force microprobe (AFM) system designed specifically for accurate submicron critical dimension (CD) metrology. The system includes 2-D AFM sensing, 3-D position interferometry with 1.25 nm sensitivity, and a special tip design. Unlike conventional AFM scanning systems, the system operates like a nanorobot moving from point to point under computer control and sensing surfaces without making contact. The system design, operating characteristics, and application to metrology are
