5 CHARACTERISTIS TO COMPARE BEFORE PURCHASING A PROBE STATION UNIT

The probe station unit has undergone numerous technological advances over the past decade. Researchers now have more options to settle on from which is useful but can make it difficult to effectively compare unique probe station units before purchasing. This tool represents a big financial investment so it's important to pick the simplest solution for today and tomorrow. Fortunately, that specialize in five key characteristics can make the comparison process easier and more accurate.

1. With the growing popularity of cryogenic measurements time-consuming wiring of an on-wafer device is not any longer necessary. Today's platforms leave visualization and electrical interrogation of multiple wafer level devices. Unfortunately, this comes with a trade-off. Optical access to inflexible probing of a tool can transfer heat loads from the probe arm to the device being tested. to attenuate this effect, it's essential the probe station unit has some sort of shield or other technology to scale back thermal radiation on the sample. Multiple experiments have shown that even the littlest amount of thermal radiation transfer can alter the top results.

2. Another characteristic to match before purchasing a search station unit is that the ability to form automated variable temperature measurements. Traditionally, probe arms are anchored to the sample stage and therefore the probe tip will move because the sample stage warms. This makes it difficult to automate variable temperature measurements because the probes must be lifted and re-landed for any noticeable temperature transition. the power to make stable tip position which allows for continuous measurements is critical. Not only does it ensure accuracy but it also provides increased measurement functionality.

3. The sample holders on the probe station unit must be compared also . Most units offer a spread of sample holders to settle on from. Popular options include a grounded sample holder, co-axle sample holder, and isolated sample holder although several additional options are available also . When comparing units, it's critical to make sure researchers can use the required sample holder required to accurately complete their experiment.

4. The probe station units' vision system is critical to match before purchasing. this technique is liable for distinguishing characteristics of the sample and properly landing probes. Depending upon the experiment the extent of detail provided by the vision system varies. Thus, researchers must consider current experiments also as future needs when comparing vision systems.

5. the ultimate characteristic to match before purchasing a search station unit is overall system versatility. Considering the many upfront cost, it's imperative researchers make the foremost out of their unit by selecting an option which allows for successful research utilizing a spread of methods. As more probe station units become customizable or modular overall flexibility and research capabilities still expand.

Considering the many financial investment required to get a top quality probe station unit it's not surprising what proportion time and resources are wont to accurately compare available options. By that specialize in the five key characteristics an accurate comparison are often completed quickly and simply .
