ContactDr. Raluca Gearba[1]—
Step height measurement range260 µm to 10 nm[1]—
Maximum sample size6 inches[1]—
Tool type—plasma stripper; barrel reactor[2]
Process—dedicated to dry resist stripping[2]
Etching character—purely chemical and isotropic[2]
Plasma source—oxygen plasma (RF capacitive or micro-wave)[2]
Automation—completely computer driven[2]
Carrier—quartz samples carrier[2]
Carrier wafer size—4 or 6 inches[2]
Batch capacity—up to 25 wafers[2]
Resistance etch rate used at CMi—0.035 um/min[2]
Type—Barrel reactor[2]
Chamber configuration—Barrel acts as Faraday cage, RF waves do not enter chamber; plasma UV radiations not filtered[2]
Maximum wafers per batch—25[2]
Wafer carrier—Quartz samples carrier (4 or 6 inches)[2]
Mean resist etch rate—0.035 µm/min for PR (for 5, 30, or 60 min recipes)[2]
Computer control—Completely computer driven[2]
Etch type—Purely chemical, isotropic[2]
Wafer carrier sizes—4 or 6 inches[2]
Mean PR etch rate—0.035 µm/min[2]
Standard process recipes—PR Ox5 (5 min), PR Ox30 (30 min), PR Ox60 (60 min)[2]
Reactor type—Barrel reactor[2]
Process type—Dry resist stripping; etching processes are purely chemical and isotropic[2]
Reactor shielding—The barrel acts as a Faraday cage so RF waves do not enter the treatment chamber[2]
UV behavior—Plasma UV radiations are not filtered and thermally activate the oxidation[2]
Control—Completely computer driven; the only manual handling is the loading/unloading step of the quartz samples carrier[2]
Recipe PR Ox5 (5 min)—Mean etch rate 0.035 µm/min; stripping of PR residuals after photolithography[2]
Recipe PR Ox30 (30 min)—Mean etch rate 0.035 µm/min; stripping of ~1 µm of PR[2]
Recipe PR Ox60 (60 min)—Mean etch rate 0.035 µm/min; stripping of ~2 µm of PR[2]
Forbidden materials—Cu, Ag, Au, Cr — equipment must remain microelectronic compatible[2]
Primary use—dry resist stripping[2]
Carrier type—quartz samples carrier[2]
Carrier capacity—up to 25 wafers[2]
