FAQs: Precision Base Plates for Semiconductor Machinery Applications

We provide comprehensive finishing solutions tailored to aerospace requirements:
Anodizing (Type II and Type III)
Passivation for corrosion resistance
Precision polishing for aerodynamic surfaces
Custom protective coatings and thermal barriers

All components, along with precision base plates, are produced with respect to signed and sealed quality workmanship and ISO 9001 certified quality management systems. Within certified order material traceability, including thermal stability and expansion within controlled limits, all elements included base plates, are developed utilizing advanced calibrated laser interferometry systems which guaranteed dimensional verification along with complete measurement. All elements with respect to vibration control, flatness, surface mapping, and adherence to semiconductor equipment documented specifications, including the SEMI standards, are included. Along with seismic bracing, distinct cleanroom compatibility, and structural stability provisions, a signed sealed quality control document certifies alignment control maintained within a specified range and over a multi-year service life.

Yes, we provide rapid prototyping to verify fit and test assembly, with same-day CAD-to-part capability available for critical projects. For custom automation cells and research platforms, we perform low-volume production of 20 to 500 brackets. For standardized robot models, we perform high-volume production of thousands to tens of thousands of brackets annually, incorporating complete dimensional inspection, flatness verification, and material certifications.

For equipment base plates, especially for those supporting lithography tools, metrology systems, and process chambers, flatness for the base plates of 5 microns within 5 to 25 microns per meter to ensure uniform support and vibration isolation is a big achievement. For parallelism, the control of opposite surface alignment is 0.002 inches per foot, perpendicularity is within 0.003 inches, and absolute center of the equipment isolation areas is < 0.8 Ra microns surface finish is maintained for contact surfaces to achieve the dimensional stability of 25 microns between 20 and 23 degrees, which is a big achievement for equipment supporting sub-micron positioning accuracy. The equipment base plates are sub-micron positioning accurate in the process chambers, lithography tools, and metrology systems.

Using precision surface grinding within the time frames mentioned allows for an additional control of the flatness, even reaching 5 microns, 7 microns, or 8 microns per meter which would then allow for a surface finish of 0.8 Ra microns. Control of the position accuracy within ±0.010 inches of CNC milling allows for the creation of bolt hole patterns, which then allows for placement of alignment of equipment for adjacent interface features. The drilling surface indicates the control of anchor bolt holes, leveling screw holes, and the utility penetrations. Lapping allows for a great control and precision of flatness of 5 microns for critical metrology applications. Over the years the fabrications of steel will experience stress-relief annealing which allows for the dimensional stability of 25 microns within the ‘x’ time frame period, eliminating residual stress. For custom shapes, garage casting allow the creation of custom shapes.

Aspects like durability, cost, and machinability are taken into consideration for choices of base plates. Granite (black granite and diabase) has excellent performance in metrology applications. Stability over decades at flatness is also achievable within microns. Lower thermal expansion is also a great advantage at below 8 ppm/K. Much better vibration damping is also a great advantage as it reduces resonance by 10 times when compared to steel. Long-term vibration damping stability also acts as a great advantage. The cost of Meehanite cast iron works along class 40 cast iron as it dissipates vibration having high mass. It also possesses the same damping characteristics as vibration isolation and the same stability and machinability for mounting features. Sculpted steel fabrications offer high strength for structures intended to support over 10,000 kg. Along structures, they also provide sophisticated design flexibility for structures. Integrating seismic bracing, folding and fusion also provide the designed flexibility for complex geometries.
