Gate Deposition Mask for Interdigitated ITO OFETs

Order Code: E271


(excluding Taxes)


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.

Update: As part of our program of product improvement we have decided to simplify the masks available. Each type of mask is now available as a two sided mask. On one side a spacer and substrate holder are welded to the mask and on the other just a substrate holder. This will allow our customers to both options available to test out if they are uncertain which is best suited for their work. It also means you only need to purchase a single mask rather than two if you would like to use both systems.

Please note that the single sided masks will only remain available while stocks last. However, if you are concerned that the double sided masks will be too thick for your evaporator then please do get in touch as we will be happy to help with this.
