| ==Exposure dose for mask aligners== | | ==Exposure dose for mask aligners== |
| The exposure doses listed below are for ''generic'' good exposure results, and can be a compromise between getting good lines, as well as good dots, in both clear field and dark field exposures. The optimal dose for any given specific project, could be different from the listed values.
| | [[Specific Process Knowledge/Lithography/Resist/UVresist/exposureDoseMaskAligners|Information about the exposure dose for mask aligners can be found here.]] |
| | |
| All doses are for standard silicon wafers, unless otherwise stated. Development is done using 2.38% TMAH (AZ 726 MIF).

| | |
| ===Aligner: MA6-1===
| |
| The Aligner: MA6-1 has an i-line notch filter installed. This produces an exposure light peak around 365 nm with a FWHM of 7 nm.
