Wafer Scale Glass Blowing
- Technology Application
- Microscopic gas confinement chambers, micro-lenses, optical switches, laser fusion targets, magnetic shielding, medication capsules, lab-on-a-chip, drug delivery systems
- Detailed Technology Description
- This invention describes a process for shaping glass on a wafer scale and how multiple micro-glass spheres can be formed simultaneously on a silicon substrate. These wafer attached spheres allow for integration with conventional micro-fabricated components and can be filled with any type of gas in post-fabrication.

Title: Self-inflated micro-glass blowing
Usefulness: Self-inflated micro-glass blowing
Summary: Method for fabricating self-inflated micro-objects. Uses include but are not limited to microlenses and small gas confinement chambers useful for drug delivery and diagnostic devices, complex three-dimensional microfluidic networks for gas analyzers or miniature drug delivery systems, spacers and hermetic enclosures for wafer-level packaging, micro discharge lamps and plasma light sources, and micro-optical components.
Novelty: Fabrication of self-inflated micro-objects on microscopic level by simultaneously forming blown micro-objects in glass sheet on wafer by continued application of thermally generated pressure for predetermined time

- *Abstract
-
Large scale confinement chambers have been created in the past using traditional glass-blowing techniques. However, conventional glass-blowing can only be used to create large components and requires the components to be made one at a time. Micro-glass spheres have previously been fabricated by letting glass particles fall through a temperature-controlled drop tower. While it is possible to create hollow spheres by introducing a blowing agent in the glass, these micro-spheres are not attached to a substrate and are therefore difficult to integrate with micro-machined components on a wafer.
