摘要： A method for evaluating reticle registration between two reticle patterns. A wafer is defined and etched to form a first exposure pattern, by photolithography with a first reticle having a first reticle pattern thereon. A photoresist layer is formed over the wafer and defined as a second exposure pattern, by photolithography with a second reticle having a second reticle pattern thereon. A deviation value between the first and second exposure patterns is measured by a CD-SEM. The deviation value is calibrated according to the scaling degree and the overlay offset to obtain a registration data. The reticle registration between the two reticle patterns is evaluated based on the registration data.

摘要： A method of forming source/drain regions in semiconductor devices. First, a substrate having at least one gate structure is provided. Next, first, second, and third insulating spacers are successively formed over the sidewall of the gate structure. Subsequently, ion implantation is performed on the substrate on both sides of the gate structure using the third insulating spacer as a mask to form first doping regions. After the third insulating spacer is removed, ion implantation is performed on the substrate on both sides of the gate structure using the second insulating spacer as a mask to form second doping regions serving as source/drain regions with the first doping regions. Finally, after the second insulating spacer is removed, ion implantation is performed on the substrate on both sides of the gate structure using the first insulating spacer as a mask to form third doping regions, thereby preventing punchthrough.
