Polishing Templates

PR Hoffman is a world leader in the design and construction of waxless mount polishing templates and fixtures. Each of these template assemblies are uniquely designed to fit each customer’s specific polishing application. PR Hoffman provides detailed product drawings as a result of leading edge machining and design equipment. This product is also finding its way into the a variety of leading edge technology industries such as LED, Sapphire, Silicon, Compound Substrates, Optics where time (and cost) can be saved on repetitive work by eliminating waxing and cleaning the wax from the part. PR Hoffman custom manufactures waxless mount assemblies for single-side polishing of silicon wafers of all diameters.


By providing the basic dimensions required for a single-sided polishing template to fit your machine, PR Hoffman can being the product design process. Other critical parameters include wafer size / hole diameter, wafer final thickness / work hole (pocket) depth, characteristics of the wafer material.


Each template is backed with a pressure-sensitive adhesive, specifically suited to withstand the effects of the polishing process. Our templates are assembled in a clean, climate-controlled environment to limit particle contamination. All template edges are milled smooth to prevent particle introduction during the polishing process. The final product is sealed in one-load packages to keep templates clean and uncontaminated until use.

Template Design


Wafer type and polishing environment will help determine the appropriate polishing pad for your application. PR Hoffman offers a variety of polishing pad to fit each application. We use a buffed porous mounting material that, when wet, produces the necessary adhesion to hold the wafer in place. The buffed mounting material allows the wafer to rotate in the pocket. To ensure that the wafer stays in place, we add a FR-4 carrier that has been CNC machines to exact customer specifications. This special manufactured FR-4 has superior thickness control and optimum surface finish.

Pad Material Guide

Deflection vs. Compression


PR Hoffman templates are made flat to stay flat. The buffed poromeric material is backed by a non-absorbent, non-compressible film. The pad stays resilient evenly across the full width of the recess, producing measurably flatter wafers. Every template is lot number identified to ensure full lot traceability after removal from clean packaging. PR Hoffman maintains raw material traceability to production lot numbers for a minimum of 5 years.

Each template lot is fully inspected by our highly trained quality team and every customer shipment includes a Certificate of Compliance Report that can additionally be delivered electronically to your quality department at the time of shipment.

Standard Features

  • Flat - The buffed poromeric is backed by a non-absorbent, incompressible film. The pad stays resilient evenly across the full width of the recess, run after run, producing measurably flatter wafers.
  • Long-Lasting - Adhesives specifically selected for this application withstand the effects of the polishing process.
  • Clean - Templates are assembled in a clean, climate-controlled environment to limit particle contamination.
  • Prevent Scratches - All edges of the FR4 template are milled smooth to prevent introduction of glass fibers during polishing.
  • Load Size Packaging - Templates are sealed in durable plastic sleeves. Each package contains only enough templates for one machine load to keep them free of contamination until use.
  • Easy Installation - The template assembly is backed with a pressure-sensitive adhesive. Just peel away the release paper and press the assembly onto the carrier, per the mounting instructions supplied with each shipment.
  • Common sizes - Template sizes (up to 600mm diameter) for common silicon wafer and other substrates, for single-side polishers using waxless mounting polishers. Templates are available to hold standard wafer diameters, and parts of any size or shape.
