NEXTERION® bonded glass substrates
CHARACTERISTICS
-
Tape Bonding
For all NEXTERION® taped-bonded products the channels are formed via adhesive tape. The channel depth is defined by tape thickness. The bonding process takes place at room temperature. This allows an optional functional coating on either top or bottom plate. -
Fusion bonding
All NEXTERION® fusion-bonded products are fully glass-based systems either in two or in three layer-designs. The layers are aligned and directly bonded via pressure contacting. The fusion bonding occurs at high temperatures (~ 500 - 600 °C). SCHOTT MINIFAB offers fully glass-based systems either in two or three layer-design. The layers are aligned either via wet (water) or via direct pressure contacting.
YOUR ADVANTAGES
Manufacturing takes place in ISO class 5 environment, all relevant processes are in place for diagnostic company needs. In the following an overview of the available bonding methods including design options.
NEXTERION® structured glass substrates
CHARACTERISTICS
1. Material
The standard glass types used for NEXTERION® glass substrates are our borosilicate glass types BOROFLOAT® or D 263®. If needed, we can also offer other options selected from the wide range of SCHOTT specialty glass materials.
2. 3-D structures
To maximize our customizability, we use multi-layer designs to create 3-D structures in glass. Structures will either be created by laser-ablation or by stacking of structured layers. This technology can also be combined with adhesive tape layers. The thickness of the layers ranges from 0.07 mm to 2 mm.
3. PreScora
The growing complexity of the consumable biochip market is driving demanding applications. Very often the further processing on wafer level is required. For diagnostic products final separation into chips, using conventional dicing processes bare a high risk of contamination. To solve this problem, we are offering pre-scored substrates that are scribed into the final chip size to be separated into the requested format at the needed step of the process chain without dicing.
