a patterned deposition a separate continuous mask can be employed for each source or alternatively a single continuous mask be employed for a plurality of sources referring to fig6 d a continuous mask 88 is provided and moved around rollers 80 in concert with substrate 10 on drum 5 fig6 a 6c and 6 d are end views of drum systems in which the substrate is wrapped multiple times around a drum at a skew angle as shown in fig5 while fig6 b utilizes a cut sheet and drum system as originally shown in fig1 each of these masking embodiments can be employed with any of the path and actuation mechanisms presented here any one or group of sources 15 20 or 25 can be employed with a patterned mask other sources cannot employ a source and any combination of patterned sources and unpatterned sources can be employed to provide a great variety of deposition layers both patterned and unpatterned if the sources are stopped and started as described in fig5 above the area of deposition will be shaped in a rhombus to provide a rectangular deposition area when the sources are stopped and started the drum 5 can be replaced by a polygonal transport system having flat faces and drums or rollers at the vertices referring to fig7 the substrate 10 is passed at an angle across rollers 80 to provide faces with sources 15 and 20 oriented at a similar angle drums 5 can also provide the transport mechanism as described above in place rollers 80 together with sources 15 and 20 fig8 shows an end view of another embodiment depicting a polygonal path with a large number.
