Thin Film Transistors (TFTs)
​Unlocking Innovation with PINA Dispersions in Thin Film Transistors (TFTs)
​Thin Film Transistors (TFTs) are a type of field-effect transistor that is composed of thin films of a semiconductor, dielectric, and metallic layers deposited on a supporting substrate. TFTs are a critical component in modern electronics due to their ability to amplify and switch electronic signals and power.
The importance of TFTs lies in their versatility and efficiency. They are used in a variety of applications, including display technology for televisions, smartphones, and tablets, where they control the display’s pixels to provide high-quality images.
Traditional TFT manufacturing requires complex lithography processes and vacuum systems. Various materials have been explored for TFTs, including traditional silicon, organics, and inorganics such as oxides, carbon nanotubes (CNTs), graphene, and other emerging 2D materials. Several organic semiconductors, such as pentacene, PQT-12, and F8T2, have been successfully applied to the printing process for TFTs.
However, traditional silicon-based TFTs require high-temperature processes, limiting their use in large-area, high-resolution electronics. While organic TFTs offer advantages like low processing temperature, large-area capability, and lower manufacturing costs, they still suffer from instability, high cost, and lower performance.
TFT's Architecture
Our specialized PINA dispersions overcome these challenges by incorporating functional metal oxide nanoparticles, enabling deposition at temperatures below 100°C. This low-temperature process allows for a broader range of materials and substrates, creating new possibilities for TFT applications.
Additionally, PINA dispersions offer enhanced film stability, with a lifespan exceeding 10 years, as proven by passing the Standard Damp Heat Stability Test (IEC 61215). This ensures long-lasting, reliable TFTs, even in harsh environmental conditions.
PINA dispersions are compatible with low-cost, large-scale production techniques such as inkjet, spray, and roll-to-roll (R2R) printing. This compatibility allows for the economical and efficient production of TFTs, making our inks an excellent solution for the current challenges in TFT technology.
