Solution processable OFET and sensor substrates

Substrates with pre-patterning of the ITO to act as a source and drain contacts allows for entirely solution processed OFETs, sensors and chemiresistors (as well as many other device types) with no need for vacuum processing or thermal evaporations.

Note that this system is pin-compatible with the low-density OFET test chips and processing equipment. Gate deposition masks are not required for solution processed gates but are also provided to allow for mixed vacuum and solution processing where appropriate.
