Gate Deposition Mask - ITO OFETs

Product Code E271-SPC
Price $300.00 ex. VAT

An evaporation mask for deposition of gate contacts onto Ossila's pre-patterned ITO substrates (S161). The T-shaped aperture allows the gate to cover the interdigitated source-drain contacts while also providing easy electrical connection via the Ossila USB test board.

Mask with direct contact: For sputtering and other non-directional deposition systems, as well as for thermal deposition systems with oblique angles or a very short throw, we recommend the use of the direct contact mask to get well-defined edges.

Mask with 200 μm spacer: For normal thermal evaporation systems we recommend the use of masks with the 200 μm spacer to help avoid scratches and allow better out-gassing.


Size 75 mm x 75 mm

Material Stainless steel
Capacity 12 substrates (S161 or S162)
