| 20100009497 | PERFORMANCE IMPROVEMENTS OF OFETS THROUGH USE OF FIELD OXIDE TO CONTROL INK FLOW - An OFET includes a thick dielectric layer with openings in the active region of a transistor. After the field dielectric layer is formed, semiconductor ink is dropped in the active region cavities in the field dielectric layer, forming the semiconductor layer. The ink is bounded by the field dielectric layer walls. After the semiconductor layer is annealed, dielectric ink is dropped into the same cavities. As with the semiconductor ink, the field dielectric wall confines the flow of the dielectric ink. The confined flow causes the dielectric ink to pool into the cavity, forming a uniform layer within the cavity, and thereby decreasing the probability of pinhole shorting. After the dielectric is annealed, a gate layer covers the active region thereby completing a high performance OFET structure. | 01-14-2010 |
| 20100006826 | INCREASING YIELD IN OFETS BY USING A HIGH-K DIELECTRIC LAYER IN A DUAL DIELECTRIC LAYER - Dielectric layer pinholes in OFET structures are addressed through the addition of a high-K dielectric layer to eliminate the effects of shorts in the dielectric layer. The original dielectric layer is maintained such that the semiconductor/dielectric interface remains unchanged. The high-K dielectric layer contributes material to the gate dielectric to plug up pinholes in the original dielectric, but does not contribute significant capacitance due to the high dielectric constant of the additional dielectric layer. The incidence of pinholes in the dielectric layer is reduced without significantly affecting the performance of the OFET transistor. | 01-14-2010 |

| 20080220562 | Structure And Fabrication Of Self-Aligned High-Performance Organic FETs - A low channel length organic field-effect transistor can be produced in high volume and at low cost. The transistor structure includes successively deposited patterned layers of a first conductor layer acting as a source terminal, a first dielectric layer, a second conductor layer acting as a drain terminal, a semiconductor layer, a second dielectric layer, and a third conductor layer acting as the gate terminal. In this structure, the transistor is formed on the edge of the first dielectric between the first conductor layer and the second conductor layer. The second conductor layer is deposited on the raised surfaces formed by the dielectric such that conductive ink does not flow into the trough between the dielectric raised surfaces. This is accomplished by coating a flat or rotary print plate with the conductive ink, and applying the appropriate pressure to deposit the materials only on the raised surfaces of the dielectric. The second metal is automatically aligned to the layer beneath it. Due to this self-alignment and the short channel formed by the thickness of the dielectric material, a high-performance FET is produced without the requirement of high-resolution lithography equipment. | 09-11-2008 |
