Fabrication Of Micro/Nanowire Arrays Via Template-Assisted Hot Embossing

Patent Status

Patent Pending

Brief Description

Creating complex structures at extremely small scales is essential for advancing fields ranging from electronics to medicine. Researchers at UC Berkeley have developed a template-assisted hot embossing method to fabricate arrays of architected micro-scale and nano-scale structures.

Suggested uses

• Advanced Semiconductor Manufacturing: Creating precise patterns for next-generation electronic components and integrated circuits.

• Optical Metasurfaces: Fabricating nano-scale structures for lenses, filters, and other light-manipulating surfaces used in imaging and communications.

• Biomedical Engineering: Developing textured surfaces for cell growth scaffolds, drug delivery systems, or micro-needle arrays.

• Structural Materials: Producing lightweight, high-strength lattice structures or architected materials with unique mechanical properties.

• Energy Storage: Manufacturing high-surface-area electrodes for advanced batteries and supercapacitors to improve charging rates and capacity.

Advantages

• High Precision: Delivers exceptional fidelity in replicating micro-scale and nano-scale features from a master template.

• Scalability: The approach is well-suited for producing large-area arrays of structures efficiently.

• Material Versatility: Can be applied to a wide range of solid materials that can be softened through temperature control.

• Structural Complexity: Enables the creation of "architected" structures that are difficult to achieve with traditional subtractive manufacturing or standard lithography.

• Cost-Effective Fabrication: Reduces the need for expensive high-vacuum equipment or complex chemical etching processes typically used in nano-fabrication.
