    摘要: A semiconductor wafer is disclosed that includes a plurality of fields, including a plurality of alignment fields. Each alignment field includes a plurality of intra-field small scribe lane primary mark (SSPM) overlay mark pairs there around. The SSPM mark pairs allow for in-situ, non-passive intra-field alignment correction. In one embodiment, there may be between two and four alignment fields, and between two and four SSPM mark pairs around each alignment field. The SSPM marks of each mark pair may be extra scribe-lane marks.

    摘要: Reducing photoresist shrinkage by plasma treatment is disclosed. A semiconductor wafer having one or more photoresist layers is plasma treated, such as plasma curing, plasma etching, and/or high-density plasma etching the wafer. After plasma treating, one or more critical dimensions on the photoresist layers is measured using an electron beam, such as by using a scanning electron microscope (SEM). The plasma treating of the wafer prior to measuring the critical dimensions using the electron beam decreases shrinkage of the photoresist layer when using the electron beam.

    摘要: A method of automatically forming a rim PSM is provided. A first pattern comprising a conventional original pattern as a blinding layer and assist features around the conventional circuit pattern is designed. A portion of a Cr film and a portion of a phase shifting layer under the Cr film are removed with the first pattern. The removed portion of the Cr film and the removed portion of the phase shifting layer are positioned on the assist feature. A second pattern comprising the conventional circuit pattern and a half of the assist features is designed. A portion of the Cr film in positions other than on the second pattern is removed. The convention circuit pattern formed at the mask medium is defined as the blinding layer. The area of the assist features only comprise a quartz substrate that light can pass through. The other areas of the mask medium wherein the phase shifting layer remains is defined as the phase-shifting portion of the PSM.
