Lithography pattern shift
Web(stepper) that is used in the lithography process is becoming increasingly shorter, and new trends in the field of reticle fabrication include the addition of OPC (optical proximity correction) patterns (see Fig. 1), the use of phase shifting masks, and so on to further extend the resolution limit. In this report, we describe the HL-900M Series Web1. print the first pattern as in standard DPL processes; 2. shift the photomask of step (1) by a predetermined nanoscale amount X (equal to minimum gate pitch for poly-layer ST-DPL) and print the second pattern; 3. apply a non-critical trim (a.k.a. block) exposure to remove unnecessary features. The translational mask shift in step (2) is ...

Web28 dec. 2016 · We propose an arbitrary pattern lithography process using interference of Bose-Einstein condensates (BECs). A symmetric three-pulse Raman atom interferometer (AI) is used to implement the system. The pattern information, in the form of a phase-only mask, is optically encoded into the BEC order parameter in one of the AI arms. The …

Web1 dag geleden · Lithography Pattern Shifts Induced by Dipole-Illuminated EUV Masks by Fred Chen on 12-19-2024 at 10:00 am Categories: Lithography As EUV lithography is being targeted towards pitches of 30 nm or less, fundamental differences from conventional DUV lithography become more and more obvious. A big difference is in the mask use.
WebIntroduction. Photomasks used for optical lithography contain the pattern of the integrated circuits. The basis is a so called blank: a glass substrate which is coated with a chrome and a resist layer. The resist is sensitive to electron beams and can be transferred into the chrome layer via etch processes. The chrome represents opaque areas on ...
