Application Examples:

Modular Wafer Inspection with pco.edge 5.5

Silicon carbide (SiC) is a wide bandgap semiconductor, which is especially used for high-power, high-temperature and high-frequency devices due to its high energy efficiency. Despite great improvements in the material quality of SiC substrates and epitaxial wafers within the last years, critical defects like stacking faults (SFs) and basal plane dislocations (BPDs) can still lead to bipolar degradation and finally to complete failure of the device.

Fluorensce Microscopy DNA Micro Arrays with pco.edge series

Microarrays are versatile tools for high throughput screening. Nevertheless they are severely limited. Either the molecules are synthesized in-situ directly on the surface or in-vitro or in-vivo produced externally and then transferred onto the surface. In-situ synthesis shows low yield in terms of purity and restricts therefore the biomolecule probe length to ~50 bp for light-synthesized DNA (Affymetrics) or ~200 bp print-synthesis (Agilent), but allows up to millions of spots per array. Ex-array synthesis on the other hand provides high-purity molecules, but the (bio)synthesis and purification of these molecules is tedious, time consuming and expansive. Also the printing process takes time. Even if one spot can be made per second 100,000 spots will take more than a day. Therefore the idea arose why to copy microarrays. Why not make DNA, RNA and protein microarrays as high quality copies of a high quality original? It worked fine for text books and images. So why not apply it for DNA? Why not build a biomolecule copying machine? A biomolecule xeroxer? Read more about this here.
