b forms on second surface 320 of sacrificial mask 312 second surface 320 of sacrificial mask 312 becomes the land area for evaporant material that does not pass through apertures 322 whereupon layer 212 forms thereon by condensing and solidifying during one or more deposition events fig4 b illustrates how sacrificial mask 312 between apertures 322 deforms as a result of one or more deposition events while at the same time deposition mask 310 between apertures 322 is not deformed specifically sacrificial mask 312 between or adjacent apertures 322 curls or warps away from second surface 316 of deposition mask 310 whereupon the edges of apertures 322 of only sacrificial mask 312 lift away from second surface 316 of deposition mask 310 the material of sacrificial mask 312 between apertures 322 curls because of the difference in stress between sacrificial mask 312 with its surface compressed and layer 212 with its surface tensioned that is deposited thereon however the intimate contact of first surface 314 of deposition mask 310 against substrate 210 is maintained even though evaporant material may spill into the gap between first surface 318 of sacrificial mask 312 and second surface 316 of deposition mask 310 even though evaporant material fills this gap it does not have a curling effect on deposition mask 310 because there is no continuous run of.
