Probe Benchtop Wafer Chucks: Three Applications

In most applications, vacuum wafer chucks are preferred over mechanical wafer chucks because they hold wafers in place while probing.

Materials for semiconductors

Materials used for insulation

Inkjet technology is also used to print insulating materials.

In the latest technological advances in insulating materials, low defect densities and high quality interfaces have been produced, probe stationso our selection of these active materials is appropriate for use as gate dielectric films or passivation layers.

In response to the polarization induced by an electric field applied to the gate electrode, test probegate dielectric films play a very important role in influencing the ability to accumulate charge carriers in the active layer.

The biomaterials industry

For the printing of biomaterials, high resolution patterns are required for DNA, proteins, and hydrogels. Conventional inkjet printing has numerous biological applications, but its low resolution is an obvious limitation when printing biomaterials. A fine jet of biological material can be produced by EHD jet printing technology, which produces fine jets of biological material. The resolution can be improved by increasing the number of dots per unit area.

The EHD printing method can be used to fabricate DNA probes, including nano-sized droplets on the surface of inexpensive DNA microarrays. The size of the DNA droplets can be controlled by adjusting the electric field strength.

With EHD jet printing,micromanipulator complex lists of Unicode geometries have been used to generate single-stranded and double-stranded DNA profiles. To detect the fluorescence of adenosine molecules, these patterns were used to construct a nucleic acid aptamer-based biosensor.
