Highly Efficient Transistors for Low-Cost Organic Circuitry

The Johns Hopkins University seeks a partner to commercialize a highly efficient and novel method for fabricating multiple types of organic field effect transistors (OFETs) from one organic semiconductor (OSC) thin film. OFETs show promise as building blocks for low-cost, large-area, and flexible electronics for applications such as displays, smart cards, radiofrequency identification (RFID) tags, and sensors.

Description (Set) • Complementary circuits composed of both n-type transistors and p-type transistors consumer less power and produce better quality signals compared to circuits that utilize a single carrier type (either p-type or n-type exclusively).
• Most of the best developed organic semiconductors (OSC) thin films possessing high carrier mobilities are p-type materials.
• A major challenge with the fabrication of high quality n-type transistors is that n-type OSCs are easily degraded in the atmosphere.
• This makes complementary circuits challenging to implement because of the need to pattern more than one organic semiconductor (OSC) material.
• This invention overcomes the challenges by utilizing a fabrication method that by storing a static charge in the gate dielectric before operating the OFET, which allows multiple transistor types in identical geometric shapes to be produced from the same OSC thin film.
• The method used avoids lengthy exposures of the semiconductors to high voltages and chemical treatments that can decompose the semiconductors or contacts. Proposed Use (Set) Organic electronics Patent (Set) 11/607,459
