Photo-curable resists for inkjet dispensing applied in large area and high throughput roll-to-roll nanoimprint processes
چکیده انگلیسی


• R2R-NIL is presented with high throughput roller speeds of 30 m min−1 and good pattern fidelity.
• The viscosity of the novel materials is below 20 mPas, enabling inkjet dispensing at room temperature.
• Throughput variation from 1 m min−1 to 20 m min−1 decreased double bond conversion less than 5%.

We report two newly developed photo-curable resists specifically engineered for inkjet dispensing facilitating nanoimprint lithography (NIL) in a high-throughput environment. The viscosity of the novel NIL resists was adjusted especially to enable inkjet dispensing at room temperature. The novel resists can be applied either in NIL batch processes or in high throughput processes like roll-to-roll NIL (R2R-NIL). Batch-wise imprints were performed on various substrates as Si or plastics demonstrating the distinctive application versatility of the novel materials. The very fast curing speed of these materials is discussed in detail with the aid of FT-IR and photo-DSC measurements. The experiments demonstrate a high degree of double bond conversion of about 80% after curing and a fast curing in a few seconds even at a low radiation intensity of 0.2 mW cm−2. The novel materials show excellent adhesion on different substrates and high optical transparency. The high throughput capability of the novel materials is demonstrated by R2R-NIL processes performed at a web speed of up to 30 m min−1.
