ANTGLASS manufactures semiconductor glass substrates, MEMS glass wafers, carrier wafers, TGV substrates and advanced packaging glass components. We supply the base glass and complete precision cutting, contour machining, holes and features, grinding, lapping, polishing, cleaning, inspection and protected packaging.
Glass is used in semiconductor and MEMS systems as an electrically insulating substrate, transparent cover, temporary carrier, bonding partner, sensor interface and package interposer. The correct route depends on the material composition, coefficient of thermal expansion, alkali content, surface condition, thickness uniformity and downstream process temperature.

Material Choices for Advanced Packaging Glass
Corning EAGLE XG glass and other alkali-free glasses are used for dimensionally stable electronic and display substrates. Fused silica glass and Corning HPFS fused silica support high-purity, UV, thermal and low-expansion requirements. Borosilicate glass provides a practical route for sensors, microfluidics, bonding and laboratory devices.
Critical Wafer and Substrate Specifications
| Specification group | Items to define | Why it matters |
|---|---|---|
| Geometry | Diameter or outline, thickness, edge profile, flats or notches | Controls handling, chucking, alignment and package fit |
| Thickness control | Thickness tolerance, TTV, bow, warp and flatness | Controls bonding, lithography, coating and stack height |
| Surface | Ground, lapped or polished finish; scratch-dig or cosmetic zone | Controls bonding, optical function and film deposition |
| Features | Holes, vias, slots, channels and alignment marks | Controls electrical, fluidic and package interconnection |
| Cleanliness | Particle, residue, handling and packaging requirements | Controls yield in bonding and sensitive assembly |
Prototype-to-Production Control
ANTGLASS begins with the device drawing, wafer map or substrate specification. The material and incoming form are fixed before blanking and edge processing. Critical thickness and surface characteristics are inspected after grinding, lapping or polishing. Holes, TGV-related features and custom outlines are tied to a controlled datum system. Final cleaning and packaging are matched to the customer handling and assembly process.
Development wafers, pilot lots and repeat production are supplied with revision control and defined inspection characteristics. This supports engineering validation without separating the prototype from the future manufacturing route.
