Technology | Method | Advantages | Disadvantages |
---|---|---|---|
Nanoimprinting | Family of techniques, which use elastomeric stamps or mouds to transfer patterns to subtrates at the nanoscale. | High resolution (5-10 nm) High throughout Low cost |
High temperatures required for thermal based systems and difficulty in transfer pattern using UV systems. |
Microcontact printing | Patterns substrates by applying self assembled monolayers on an elastomeric stamp | Simple Low cost Versatile |
Lower resolution and reduced reproducibility (35 nm) |
Replica moulding (REM) | Use PDMS mould to cast the pre-polymer, which after the polymer is cured is detached. | Good resolution (30nm) Versatile Low cost |
Limited use of moulds |
