OFET Device Testing & Fabrication Equipment

About

Ossila's OFET Equipment provide several options for fabrication and testing of OFET devices. We have created an eco-system of substrates, testing systems and deposition aids to make OFET research as straight forward as possible. Most of our OFET equipment is designed around two architectures: high density and low density.By using these device designs, you can reliable and consistently change variable, and test devices quickly and easily test using our OFET test boards: The low density OFET design are designed with relatively large channels so contact effects are minimized. This means that matching energy levels matching of the active layer and the source-drain contacts is less important. Also, the 30 mm channel length produces larger currents for quicker measurements that can be measured with less sensitive equipment. High density OFETs allow you to test up to 20 OFETs on a single substrate. This makes testing OFET devices quicker with better statistical results.

In thermal evaporations, OFET layers are heated in vacuum conditions until they vaporize. The vaporized materials travel upwards then condense onto a substrate, forming uniform layers. Thermal evaporation is widely used because it produces high-purity films and enables the fabrication of multilayer OFET structures with well-defined interfaces.
