Process
-
Mold Fabrication: A master mold is created using electron beam lithography or other high-resolution patterning techniques.
-
Substrate Preparation: A substrate is coated with a thin layer of material, such as polymer or metal, which will act as the resist.
-
Step: The mold is brought into contact with the resist-coated substrate and pressure is applied.
-
Stamp: The mold is then separated from the substrate, leaving the pattern imprinted in the resist.
-
Pattern Transfer: The pattern is transferred to the substrate by etching or other processes.
Advantages
-
High Resolution: SSIL can achieve sub-100 nm feature sizes with high precision.
-
Pattern Flexibility: The mold can be used to create complex and arbitrary patterns.

Essential Questions and Answers on Step and Stamp Imprint Lithography in "MISCELLANEOUS»UNFILED"
What is Step and Stamp Imprint Lithography (SSIL)?
SSIL is a nano-patterning technique that utilizes a flexible elastomeric stamp to transfer patterns onto a substrate. The stamp is fabricated with desired features and pressed onto a spin-coated photoresist on the substrate, transferring the pattern via physical contact.
What are the advantages of SSIL?
SSIL offers several advantages, including:
- High resolution and precision: Enables the creation of patterns with sub-10 nm resolution.
- Cost-effective: Utilizes simple and inexpensive fabrication processes.
- Versatile: Can be used on various substrates, including flexible and curved surfaces.
- Compatible with various materials: Can transfer patterns to both organic and inorganic materials.
What are the limitations of SSIL?
SSIL has a few limitations:
- Pattern transfer fidelity: The fidelity of the transferred pattern can be affected by factors such as stamp deformation and resist properties.
- Large-scale patterning: SSIL is mainly suitable for small-scale patterning, as the size of the stamp limits the patterning area.
- Aspect ratio: The height of the transferred features is limited by the stamp's thickness.
What applications does SSIL have?
SSIL finds applications in various fields, such as:
- Microelectronics: Fabrication of transistors, integrated circuits, and flexible electronics.
- Optics: Creation of optical elements, lenses, and holographic patterns.
- Biomedical engineering: Patterning of scaffolds for tissue engineering and drug delivery systems.
