Photolithography is a process that uses light to transfer a geometric pattern from a photomask to a light-sensitive chemical photoresist on the substrate.

This method is highly effective in shaping ceramics for electronic and sensor applications.
It offers high precision and is widely used for its ability to create complex patterns on ceramic films.

2. Soft Lithography

Soft lithography uses elastomeric stamps to generate patterns, offering a low-cost alternative with high precision.

This technique is ideal for creating microstructures that require flexibility and can be adapted for use with various ceramic materials.

3. Laser Micromachining

Laser micromachining involves the use of laser beams to machine ceramic materials at a micro-level.

It allows for the precise engraving and cutting of ceramic products, enabling complex designs that are otherwise difficult to achieve.
Laser micromachining is beneficial in producing micro-scale components for medical devices and electronic applications.

4. Additive Manufacturing

Additive manufacturing, or 3D printing, has opened new horizons for ceramics.

Through this process, ceramics can be layer-by-layer fabricated, which is essential for customized and highly detailed ceramic components.

It enables the direct manufacturing of parts, significantly reducing time and material costs.
