Enhancing Yield in Semiconductor Epitaxy with Advanced Power and Temperature Control
Precision control is essential to maximize quality and yield in high-temperature manufacturing processes. In semiconductor epitaxy, failing to accurately measure and promptly respond to changes may result in crystal quality degradation, ultimately affecting reliability, performance, and yield.
This blog explores how the shift to advanced electrical heating and the invention of rapid-response Silicon Controlled Rectifier (SCR) power controllers enables these improvements in semiconductor epitaxy. Specifically, Advanced Energy’s latest generation of SCR power controllers (Thyro-XD™) were developed to deliver the industry’s highest accuracy (10X improvement from ±4.5% to ±0.25%), repeatability and fastest response time in highly dynamic high-temperature manufacturing processes.
Applied Thermal Control is proud to introduce the G-Series and MG-Series recirculating chillers, the latest evolution in our product line up, designed for high-performance cooling with a lower environmental impact. These new ranges utilise R290, offering improved efficiency and sustainability while maintaining the reliability and precision our customers expect. The G-Series and MG-Series supersede our previous K-Series and M-Series chillers, delivering advanced features and optimised designs to meet the demands of modern laboratory and industrial applications.
Whether you require compact cooling solutions or advanced touchscreen functionality, these next generation chillers provide superior temperature stability, energy efficiency, and long-term value.
Metal products and components cannot last long in their bare form, which is why surface treatment becomes necessary. There are various methods for surface treatment, such as painting, plating, thermal spraying, heat treatment, and vacuum film coating (vapor deposition). Among these methods, vacuum film coating (vapor deposition) requires a high vacuum environment and improves hardness and wear resistance.
Vacuum film coating (vapor deposition) methods can be broadly divided into two groups: Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD). PVD is a deposition method where solid materials are vaporized by heat or plasma and the vapor condenses on the surface to form a coating. Depending on how the solid material is vaporized, it can be further categorized into thermal evaporation, ion plating, and sputtering methods. On the other hand, CVD uses chemical reactions where a precursor gas containing the elements for
Optix For Vacuum Heat Treatment and Vacuum Metallurgy
Gencoa Optix is a robust and easy-to-use compact gas sensor that provides critical information from vacuum environments. Optix is ideally suited to improving productivity and preventing failed production cycles on vacuum metallurgy and heat treatment processes.
Optical Gas Sensing
Optix is a robust and easy to use device to track the gases present during vacuum processing. The nature of a vacuum means that any potential problem can be identified by monitoring the different gases present.
In contrast to in-vacuum mass spectrometry-based gas detectors, Optix uses light from a small remote plasma on the chamber wall to detect the gas concentrations. The detector (spectrometer) is located in atmosphere, and therefore protected from damage at all times.
Another major advantage is the ability to work from near atmosphere down to 10-7 mbar, without the need for any differential pumping. As the chamber pressure
Control loops are systems applied by design engineers in various industrial applications to maintain process variables (PVs) at a desired value or set point (SP). Control loops are important for maintaining the stability of a system, and for consistently producing the desired outcome of a process.
A temperature control loop is one of the most common examples of a control loop. Control loops work to maintain the temperatures in our homes and offices. They are used for a range of immersion and industrial heating systems as well. Temperature control loops are set up as follows:
-The process to be controlled is established. In the case of a temperature control loop, this refers to the temperature of a substance that is being heated, such as water temperature.
-Sensors measure the process value (PV), or in this case, the current value of the temperature. Sensors come in the form of thermostats in domestic heating
