The station's research unit was making numerous technological advances over the last decade. Researchers now have more choices to choose, which is beneficial, but it can be difficult to compare individual units of the cache site effectively before buying. Fortunately, the comparison process can be focused more easily and accurately on five main functions.
1. With the increasing popularity of cryogenic measurements, the delayed wiring of an on-wafer device is no longer necessary. Current platforms enable visualization and electrical interrogation of different wafer level devices. Optical access to inflexible probes of a device can transfer heat loads from the probe arm to the device to be tested.
2. Another possibility to compare to purchase a probe station unit is the ability to make automatic variable temperature measurements. Traditionally, the probe arms are anchored to the sample, and the point of the probe moves as the sample level increases. This makes it difficult to automate variable temperature measurements, as the probes need to be increased and ground again for any visible temperature transition. The ability to provide a stable peak position that allows continuous measurement is critical. It not only guarantees the accuracy, but also offers a greater measurement function.
3. The sampling supports in the probe station unit must also be compared. Most units offer a variety of samples to choose from. Popular options include a grounded model holder, a cylindrical shaft holder and an isolated sample holder, although there are several additional options. When comparing units, it is crucial to ensure that researchers can use the sample support needed to complete their experiment accurately.
4. The display system of the probe station units is crucial to comparing for the purchase. This system is responsible for the distinction between sampling properties and associated scary probes. Depending on the experience, the detail level of the vision system varies. Researchers should consider current experiences and future needs when comparing vision systems.
5. The final function to compare before purchasing a probe station unit is the overall versatility of the system. Since more probe station units are adaptable or the overall flexibility and search functions are further expanded.
Given the considerable financial investment needed to acquire a quality research station, it is not surprising how much time and resources are used to accurately compare available options.
