CXT – Chemically Resistant Template

CXT – Chemically Resistant Template

Chemically Resistant Templates, specially designed for harsh environments and the slurry for polishing Silicon Carbide (SiC), are the latest innovation in polishing fixtures that PR Hoffman has to offer. CXTs can be used in any polishing application, flip polish, touch polish, single side polish or CMP. This product helps to save both time and money by eliminating the repetitive work required when waxing mounting, de-mounting and then cleaning the wax from the part. It is also a seamless single shell construction to prevent slurry incursion but improves COO. This product has been proven to withstand environmental and processing temperature variations.

CXT – Chemically Resistant Template Design

PR Hoffman begins the product design process by gathering information about your part and processing environment. This will assist in a custom designed product specification drawing. Material type, thickness, shape, along with machine parameters including slurry type, pH levels, machine processing pressures and temperatures all contribute to making the most durable product with the highest quality polished surface. PR Hoffman offers a variety of solutions for your processing parameters, that will result in high quality polished wafers.


Each CXT 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 and CXT edges are milled smooth to prevent particle introduction during the polishing process. The final product is sealed in poly-bags, per your specific machine load size, to keep templates clean 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. The pad material guide will provide options for the standard template. Customers who use the CXT are able to have a pad that is specifically designed for use with SiC wafers and KMn04 based slurries. Template and CXT frames are manufactured using the highest quality raw materials procured to our specific thickness tolerances.

Pad Material Guide


Every Template and CXT 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 and CXT lot is fully inspected by our 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.
