Probe Station

Wafer-Level Testing
Probe stations are essential for wafer-level testing in fields like semiconductor manufacturing. Before a wafer is diced into individual chips, it undergoes testing to assess the performance of each die. This early-stage testing helps manufacturers identify faulty dies, reducing waste and improving overall production efficiency.

Device Characterization
Probe stations are also used to measure a wide range of electrical parameters, including DC characteristics like current-voltage (I-V) curves and capacitance-voltage (C-V) curves, as well as RF characteristics such as S-parameters. By analysing these measurements, engineers can gain insights into the device's performance, reliability, and suitability for specific applications.

Failure Analysis
When a device malfunctions, a probe station can be used to pinpoint the root cause of the failure. By systematically probing different parts of the device, engineers can identify defective components or faulty connections. This information is crucial for improving future designs and manufacturing processes.

Research and Development (R&D)
In R&D environments, probe stations are used to test new materials, device structures, and fabrication processes. Researchers can use them to explore the electrical properties of novel materials like organic semiconductors, 2D materials, and nanostructures.

Optoelectronic Testing Stations
In addition to electrical testing, probe stations can be used to test optoelectronic devices, such as photodiodes, LEDs, and laser diodes. By integrating optical sources and detectors into the setup, engineers can measure the performance of devices that interact with light, which is crucial for applications in fibre optics, solar cells, and display technologies.

Life Sciences
These instruments are also crucial in electrophysiology, where they are used to position microelectrodes with extreme precision to record electrical activity from individual neurons or muscle cells. This allows researchers to study ion channel behaviour, synaptic transmission, and neural circuitry in real-time. In cell biology, micromanipulators are used for various tasks, such as injecting biological molecules into cells, performing patch-clamp experiments, or isolating specific cells for further analysis. They are also employed in genetic engineering for microinjection of DNA or RNA into embryos or cells, and in microdissection to manipulate or dissect small tissue samples under a microscope.
