Wafer carrierQuartz samples carrier (4 or 6 inches)[1]—
Mean resist etch rate0.035 µm/min for PR (for 5, 30, or 60 min recipes)[1]—
Computer controlCompletely computer driven[1]—
Etch typePurely chemical, isotropic[1]—
Wafer carrier sizes4 or 6 inches[1]—
Mean PR etch rate0.035 µm/min[1]—
Standard process recipesPR Ox5 (5 min), PR Ox30 (30 min), PR Ox60 (60 min)[1]—
Reactor typeBarrel reactor[1]—
Process typeDry resist stripping; etching processes are purely chemical and isotropic[1]—
Reactor shieldingThe barrel acts as a Faraday cage so RF waves do not enter the treatment chamber[1]—
UV behaviorPlasma UV radiations are not filtered and thermally activate the oxidation[1]—
ControlCompletely computer driven; the only manual handling is the loading/unloading step of the quartz samples carrier[1]—
Recipe PR Ox5 (5 min)Mean etch rate 0.035 µm/min; stripping of PR residuals after photolithography[1]—
Recipe PR Ox30 (30 min)Mean etch rate 0.035 µm/min; stripping of ~1 µm of PR[1]—
Recipe PR Ox60 (60 min)Mean etch rate 0.035 µm/min; stripping of ~2 µm of PR[1]—
Forbidden materialsCu, Ag, Au, Cr — equipment must remain microelectronic compatible[1]—
