Differential Pressure Switch/Gage within Semiconductor Fabs

semiconductor facility building outside

In simple terms, a semiconductor transistor is a part with specific electronic properties that allow it to serve as a component in microchips and modern electronics like phones, laptops, and more. As these components are small and require precise manufacturing methods, there are facilities dedicated to their manufacture.

These facilities consist of several levels including air handlers and scrubbers for exhaust, HEPA room, fab cleanroom, and subfab areas. The control of differential pressure within the facility is essential for the safety of both equipment and personnel. Continue reading “Differential Pressure Switch/Gage within Semiconductor Fabs”

What is Stability and Why is it Important?

Stability is defined as a change (or lack of change) in accuracy over a period of time.

Drift is commonly used as a specification to illustrate the stability, or change in accuracy over a period of time, commonly shown as X%/year where X = a number; i.e. 0.25%/year. In this scenario, a device with a ±1% accuracy, would be expected to have an accuracy of ±1.25% (1%+0.25%) after a period of one year. Depending on the design, brand, and range of the sensing instrument, the stability can vary widely. Continue reading “What is Stability and Why is it Important?”

What Are Room Pressure Monitors and Where Are They Used?

Hospital Isolation Room

Room pressure monitors are devices that monitor differential pressure between two rooms or areas. Differential pressure is the difference of two pressures being sensed.

There are several applications where it is important to maintain a pressure difference between two rooms. This helps to ensure that there are no contaminants entering or exiting a protected area. In a medical setting, an isolation room requires a pressure differential to make sure that no bacteria, pathogens, or viruses enter (or leave) the isolation room. This protects healthcare professionals, patients, and other guests, and minimizes the spread of germs. Room pressure monitors would also be used in areas such as: pharmaceutical manufacturing, semiconductor manufacturing, clean rooms, research labs, vivariums, and clean manufacturing areas.
