Enhancing Semiconductor Performance with Ultra-Pure Seals
The semiconductor industry operates in a highly specialized market, demanding seals that can withstand extreme chemical exposures and temperature variations. These seals play a critical role in preventing contaminants from entering the fluid stream.
Enhancing Semiconductor Performance with Ultra-Pure Seals
The primary consideration for selecting seals in semiconductor applications is their operating characteristics. Depending on whether the seal is static or dynamic, the requirements and materials differ significantly.
Static Seals: Prioritizing Chemical and Thermal Stability
Static seals, which remain stationary without relative motion, benefit greatly from the use of perfluoroelastomers (FFKM rubber). Among these, DuPont™ Kalrez® stands out for its exceptional chemical and thermal stability.

A cryopump is a mechanical device that uses a freezing process to remove gasses and vapors from a sealed space. It is commonly used in chemical laboratories and other environments where it is critical to maintaining a high level of purity. In many cases, cryopumps are used in conjunction with other types of pumps to create an ultra-high vacuum. When operating, the cryopump draws in gas molecules and then cools them to such a low temperature that they liquify. The liquid then falls into a holding compartment, leaving the area being pumped virtually free of atmospheric contaminants.
How does a cryopump work?
Cryopumps use a cryogenic pump head to remove gasses from a system. The pump head works by condensing the gas onto a cold surface, usually made of metal. The gas is then drawn into the pump body by a vacuum, and the cycle repeats.
This process is typically used in high-vacuum environments, such as those

Industrial Electric Furnaces: Cost Reduction with SCR Power Controllers
Silicon-controlled rectifier (SCR)-based power control modules (PCMs) for industrial furnaces need integrated features for precise temperature control, process reliability, product quality and cost-effectiveness.
Thermal processing control systems, such as the Rockwell Automation® Programmable Automation Controller, are fundamental to these operations. In addition, temperature measurement loops are required for control and shut-off. These are typically either thermocouples or pyrometers for harsh environments. Power control architectures that regulate energy input to furnace heaters via SCR power controllers are also essential.
Exploring Automated Single-Wafer Ashing of Compound Semiconductors
Ashing, in which the light–sensitive coating known as photoresist is removed and cleaned from an etched wafer, is one of the most important and frequently performed steps in chip fabrication. In this step, photoresist organics are “burned off” using a processing tool in which monatomic plasma is created by exposing oxygen or fluorine gas at low pressure to high–power radio waves. Previously, wafer ashing was largely done using batch–processing techniques to achieve the required throughput.
However, unlike silicon semiconductors, in which wafers are mass–produced in a standard 300–mm size, compound semiconductors are made of silicon carbide, gallium nitride, gallium arsenide, and sapphire, which can vary from 100 to 200 mm. When this is the case, significantly better uniformity of photoresist removal is required, which means better temperature and process controls. As a result, most compound semiconductor wafer
