FAQs: Structural Brackets for Semiconductor Applications
Structural brackets are components used for precise mounting, making firm connections, and ensuring alignment between modules of equipment in processing systems of semiconductors. These include chamber mounting brackets with vibration isolation supporting process modules that weigh between 100 and 1000 kilograms, robot support brackets that position wafer handling systems with 0.1-millimeter repeatability, and valve manifold mounts that combine pneumatic and vacuum distribution systems. There are equipment interface brackets that connect cluster tool modules through kinematic coupling, load lock mounting brackets that support rapid-cycle transfer chambers, overhead service brackets that route utilities and exhaust ducting, and special brackets with IBC seismic-rating and seismic mounts, adjustable alignment with precise shimming, and modular quick-disconnect brackets that enable rapid reconfiguration of tools.
Aluminum 6061-T6 and 7075-T6 deploys great level of power for their mass and lightweight structure, excellent machinability for rigid components, integrated and complex designed features, good cleanroom chemical and corrosion resistance, thermal conduction for heat dissemination, and great value for the money. Stainless steel 304 and 316L provide corrosion resistance for process chemicals and disinfectants, maintain structural rigidity for heavy structural loads (+500 kg), achieve electropolish surface finishing with Ra < 0.4 microns, and provide non-magnetism for >20 years service. Anodized aluminum offers enhanced dull surface, improved corrosion resistance, smooth, and clean ISO 14644 certified surfaces with particle free cleanroom, and low electrical conductivity where needed.
Using multi-axis CNC milling, we make brackets with lightening pockets, reinforcement ribs, and mounting bosses and we optimize for strength-to-weight ratios. Coordinate drilling gives us bolt pattern positions with ±0.005 inch precision for standard equipment mounts and kinematic mounts. Boring dowel pin holes to a precise 0.01 millimeter gives repeatable alignment. Tapping, counterboring for recessed areas, and counterboring for flush fastener control rounded out screw holes for mounting and recessed areas for metric screw holes. Stress-relief annealing, surface grinding, and motor grinding completed our control features.
For structural brackets, we achieve dimensions and tolerances such as, alignment of reference surfaces for kinematic coupling under ± 0.005 inch on flatness, separating mounting faces of a bracket under 0.010 inch on perpendicularity, dowel pin holes under ± 0.002 inch on location, and surfaces under 3.2 Ra microns. Overall dimensions of a bracket are kept under ± 0.015 inch for integration in a system, screw holes for mounting are balanced under ± 0.005 inch as control for standard equipment interfaces, kinematic coupling, and mounting surfaces with a stop surface for 3.2 Ra microns are also used for balanced structures.
Sure, we do rapid prototyping for the development of semiconductor tools with finite element analysis and structural load testing, low volume production for specialized process equipment and R&D systems making between 10 and 100 brackets, and medium to high volume production for commercial semiconductor tools which includes hundreds to thousands of brackets yearly, with all brackets being fully dimensionally inspected and load tested to validate the design capacity, surface finish, and to verify the design surface finish, particle generation testing was done to verify compliance with ISO 14644 standards, and materials were certified and composition verified down to the elemental level
All components are made with ISO 9001 quality management systems with complete traceability, verification of all design parameters and dimensions, structural load documentation, surface finish validation and compliance with SEMI equipment standards for load capacity between 50 to 2000 kg, alignment with 0.1 mm for precision positioning of equipment, particle generation below 0.1 particles per cubic foot, a service life of 15 years throughout continuous fab operation.
Finishes include clear anodizing on aluminum achieving 15 to 25 micron coating per ASTM B580 for corrosion protection and particle-free surfaces, hard anodizing for wear resistance at mounting interfaces achieving hardness exceeding 65 HRC, electropolishing on stainless steel removing 10 to 30 microns achieving Ra below 0.4 microns for Class 1 cleanroom compatibility, powder coating in cleanroom white for sealed surfaces, and specialized treatments including passivation enhancing stainless steel corrosion resistance, bead blasting for uniform appearance, and black anodizing for non-reflective surfaces in optical equipment.
There is a lot of variability in lead time. For standard brackets you are looking at 10-16 business days, but for complex brackets you would be looking at 4-6 weeks. In the mean time lets you equipment design to the next stage during the waiting time, as getting brackets for fit testing can be done in 7-10 days!
Absolutely. We work on a range of custom heavy-duty brackets designed to hold and support semiconductor processing chambers that weigh 1500 kilograms and maintain a displacement of 0.1 mm. We also manufacture kinematic brackets that have a three-contact point geometry to achieve positional repeatability of 0.01 mm for precision optical stacking. In addition to vibration isolation and damping above 10 Hz to achieve a transmission reduction of 1 percent, we also work on seismic rated brackets that integrate IBC Zone 4 elastomer seismic damping. Other designs include modular quick-disconnect brackets that allow tool reconfiguration in less than 30 minutes and specialized designs that include integrated thermally isolated brackets designed to eliminate heat transfer between modules, brackets that allow adjustable positioning, and integrated structural brackets designed to support cable management, utility routing, and remap cross-section utility routing.
There are no placement errors with mounting holes making equipment align with set interfaces including SEMI standard footprints. This stops field alterations making installations very quick. Flat reference surfaces within 0.005 inches checks surfaces that touch and spread loads uniformly preventing arm to equipment misalignment. Misstated structural brackets will cause alignments to become detrimental. Flat reference surfaces within 0.005 inches checks surfaces that touch and spread loads uniformly preventing arms to equipment misalignment. Misstated structural brackets will cause alignments to become detrimental. Integrated structural rigidity with patterned ribbing and optimized cross-sections stop deflation under rated loads as equipment is maintained during wafer robotic and processing movements. Smooth surface finishes with level Ra below 3.2 microns and rate below 0.1 particles per cubic foot meet ISO Class 5 cleanroom standards where contamination causes loss of yield. Quality materials provide dimensional stability through thermal cycling of 15 to 30 degrees and corrosion resistance to cleanroom disinfectants.
Reliable equipment mounting supports semiconductor fabrication within structural integrity keeping alignment within 0.1 millimeters, load capacity from 50 to 2000 kilograms depending on application, cleanroom compatibility meeting ISO Class 1 through Class 100 particulate requirements, and service life exceeding 15 years in 200mm, 300mm, and 450mm wafer fabs processing advanced logic, memory, and power semiconductor devices.
