Deposition masks for 25mm x 25mm patterned ITO substrates.

Create four large 48mm2 photovoltaic or LED pixels.

The S2006 deposition masks are part of Ossila's award winning prototyping platform for photovoltaic devices and light emitting diodes (LEDs). The holes in the mask align with the ITO on our patterned substrates to create 4 large pixels with areas of 48mm2.

Ossila's Deposition mask

The deposition mask has three main components: a back panel, a substrate holder and a shadow mask. The substrates are held in place against the back panel, and the patterned deposition layer is positioned above. The layers are then screwed together, keeping the substrates secure during depostion.

There is also the option of an additional spacer layer between the substrate and shadow mask, which prevents the active layer materials coming into contact with the shadow mask.

General Specifications

Material Stainless steel
Outer Dimensions 95mm x 95mm
Substrate Recesses 9
Recess Dimensions 25.3mm x 25.3mm
Thickness 1.7mm without spacer, 1.8mm with spacer (exc. bolts)

Four Pixel Electrode Mask

The Four Pixel mask overlaps the ITO on the S2006C1 25mm square substrate, creating 4 large pixels with areas of 6mm x 8mm = 48mm2. The total area of devices on a single substrate is therefore 192mm2.

Electrical connection to the electrodes can be made easily using the P2011A Test Board.

Four Pixel Electrode Mask with Busbar

The Four Pixel mask can also create an busbar of evaporated material along the top and bottom of the substrate. This helps to reduce electrical resistance during measurement.
