Manufacturing of labs-on-chips involves a wide range of conditions, including exposure to high temperatures, corrosive chemicals, and water. Glass as a substrate material is ideal for use in these environments for its chemical pureness, thermal shock resistance, and high mechanical stability. Besides, in glass parts and components very precise and smooth micro- and nanostructures can be realized.
The use of glass for microsystems is a good option if the application needs excellent optical transparency combined with chemical inertness and extreme flatness. These characteristics make it a popular material for life science and pharmaceutical applications.
Glass is also an excellent material for the integration of electrical and sensing functions for its dielectric properties, high seal resistance, and absence of auto-fluorescence. Structuring of glass is mostly done by etching and laser drilling.
At Micronit the most used types of glass are Borosilicate glass (e.g. D263®, D263Bio®, Borofloat®, MEMpax®) and Fused silica. We have experience with other types, options can always be discussed.
