Reliable vacuum performance is at the heart of all semi-conductor applications that demand highly precise automation. Wafer transport must be carried out in absolutely clean environments. Every part of a semi-conductor vacuum system needs to be manufactured with end process yield and productivity in mind. Vacuum processes like high precision cutting, die casting, coating and forming are critical in the manufacture of many products we use every day.
Expanding our Understanding
Broadly speaking, vacuum systems like those used in machining centers provide the low-pressure atmospheres that are required for advanced tool machining and testing. Vacuum environments are also responsible for major advances in our knowledge of applications like accelerators and space chambers. Our understanding of scientific applications is widened through experiments taking place in semi-conductor vacuum systems.
The Source Chamber
Low pressure chambers need to be completely sealed if they are to function optimally. Specifically in machining centers where high-precision die casting and cutting of metals is performed, sealing rings of stainless steel ensure the chamber is airtight. Seals must be used so that no unwanted air enters the vacuum. Semi-conductor vacuum systems rely on the seal integrity of the source chamber being flawlessly maintained.
Adaptor Plates
Horizontal and vertical machining centers can perform heavy duty cutting while operating at high speeds. This type of agile manufacturing uses a semi-conductor vacuum system with interlocking doors to secure the work area. When workpieces are manipulated within the machine, expensive parts may wear as these come into contact with debris. Adaptor plates serve as an essential interface between a workpiece and the machine parts, restricting wear.
Bracket Supports
Strong steel and aluminium alloy bracket supports are vital for the longevity of a semi-conductor vacuum system. Bracket supports hold vital components of a machining system in place. For example, the vacuum chamber is attached securely by means of a custom-designed bracket of stainless steel, and the machine’s motor secured with an aluminium alloy bracket to ensure stability while work takes place.
Shafts and Flanges
Commonly used in semi-conductor vacuum systems, shafts and flanges have a high requirement for reliability, rigidity and resistance to corrosion. Shafts are typically made from stainless steel that has excellent resistance to corrosion and good resistance to oxidation. Flanges made from aluminium alloy are lightweight yet strong, able to remain resistant to corrosion even when surface abrasion occurs.
Semi-Conductor Vacuum System Maintenance
Every single component within a semi-conductor vacuum system has a profound impact on the smooth operability of the whole system. Avoiding costly downtimes means taking care to regularly check and maintain all parts within the vacuum system. Early leak detection is indispensable in preventing the accidental escape of toxic substances. The failure of even one sealing ring can have serious effects. Especially in safety critical settings, the more attention paid to maintenance the better for everyone.
