Recent Advances in Organic Transistor Printing Processes

Abstract

Recent progress in organic field-effect transistor (OFET) printing processes is reviewed, and a perspective on the future of the field is discussed. The principles underlying the OFET printing techniques are introduced according to two categories: direct write printing and transfer printing. A comprehensive overview of the use of printing techniques in OFET production processes is also provided. Considerations for improving OFET device performance using printing processes are explored. Prior to OFET commercialization, the OFET printing techniques must satisfy several requirements, as discussed here.

Organic Semiconductor/Insulator Polymer Blends for High-Performance Organic Transistors

“…Organic field-effect transistors (OFETs) have received much attention as switching elements in display backplanes [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The electrical performance of OFETs is now comparable or exceeds that of amorphous Si: H FETs.…”

“…The solution process is advantageous for scale-up while minimizing processing costs. Printing processes such as the roll-to-roll process can be utilized to OPEN ACCESS mass produce OFETs, and prototype devices have been demonstrated [3]. If environmental and electrical stabilities are supplemented, OFETs can be used to enable flexible/stretchable electronics [1].…”

A Ladder-Type Organosilicate Copolymer Gate Dielectric Materials for Organic Thin-Film Transistors

“…The capacitance measurement of copolymer thin films were performed using an LCR meter (Agilent 4284A, Agilent Technologies, Santa Clara, CA, USA). Carrier mobilities (µ) were determined in the saturation regime using the standard relationship, 2 ] (I DS , source-drain current; L, the channel length; W, channel width; C i , areal capacitance of the gate dielectric; V G , gate voltage; V T , threshold voltage).…”

“…Organic thin-film transistors (OTFTs) have been an important research subject because they are indispensable elements in the development of low-cost, large-area electronics, such as paper-based displays, smart cards, radio-frequency ID tags, and sensors [1][2][3][4][5][6][7][8]. Among the fundamental components of OTFTs, namely the semiconductor, dielectric, and conductor, studies on the development and application of organic semiconducting materials have intensively been performed for the last few decades [9][10][11][12][13][14][15][16][17][18].…”

Fabrication of Organic Single Crystal Transistors Based on 5,9-Diphenyldinaphtho[2,1-b:1’,2’-d]furan Derivatives

“…Organic field-effect transistors (OFETs) promise to be useful in flexible, printable and lightweight electronic applications, such as displays, sensors and complementary integrated circuits [1][2][3][4][5]. Great effort has been put into developing new organic semiconductors for use in high-performance organic transistors.…”
