A numerical experiment of electron beam lithography (EBL) using the computer simulation tool SELID is presented and analysed. A layout of parallel lines with 0.3渭m width, situated 0.4渭m from each other, is obtained through exposure and development of the positive resist PMMA. Through a model...
Electron beam lithography (EBL) is renowned to provide fabrication resolution in the deep nanometer scale. One major limitation of current EBL techniques is their incapability of arbitrary 3d nanofabrication. Resolution, structure integrity and functionalization are among the most important factors. Here w...
Electron beam lithography (often abbreviated as e-beam lithography or EBL) is the process of transferring a pattern onto the surface of a substrate by first scanning a thin layer of organic film (called resist) on the surface by a tightly focused and precisely controlled electron beam (exposure...
Currently, PMMA is the preferred resist for e-beam lithography31,32. This “wet” resist is applied to the surface of a sample via spin-coating. Conversely, QSR-5 is a “dry” resist composed of nonpolymeric sterol molecules that is applied via evaporation. The deposition method is the onl...
This thesis addresses nanostructure fabrication techniques based on electron beam lithography, which is the most widely employed nanofabrication techniques for R&D and for the prototyping or production of photo-mask or imprint mold. The focus is on the study of novel resist and development process, as...
Electron beam lithography system and method A system and method are provided for compensating for proximity effects between selected adjacent portions of pattern elements on an integrated circuit wafer where it is determined by simulation that undesirable resist patterns will resu...

by rinsing through immersion for 30 sec to obtain PMMA resist pattern. In case of lacking the earth pin, there is little change of the width of a pattern line in all regions of pattern intervals as compared with the case having the earth pin. Accordingly, in the electron beam lithography,...

2.4.2Electron beam lithography In this class of highresolution lithography, a focused beam of electrons is used to pattern an electron reactive resist. The substrate to be patterned is kept on a stage which is placed in a high vacuum chamber. Theelectron beamis raster scanned on a thin layer...
The resist ARP13 is spun on SiN at 5000 rpm for 60 s, followed by a bake at 180 °C for 5 mins. The charge dissipation layer ARPC 5090 is spun at 2000 rpm for 60 s, then baked at 90 °C for 2 mins. Electron-beam lithography is performed with a Raith Voyager tool, using an...
