Custom Designs for Semiconductor Processing

PR Hoffman generates a custom drawing for customer review and approval before any products are made. This added service insures that our customers receive precisely the design needed for their process, on every order.

Reliable Insert Carriers for High-Value Wafer Industries

Insert Carriers for Wafer Processing: The insert carrier is an exclusive PR Hoffman design widely used in the semiconductor industry (and other high value wafer industries) to protect the edge profile of the wafer while providing the strength and durability of a traditional steel carrier. This type of carrier is commonly used for processing 100mm, 125mm, 150mm, 200mm, 300mm, and 450mm silicon wafers.

Our insert lapping carriers can greatly improve Total Thickness Variation. Using a unique combination of customized design and high-quality materials, the wafers are afforded greater freedom of rotation, which reduces TTV during the lapping or polishing process.

We offer insert lapping engineering from a variety of different high grade plastics to meet the widest possible range of processing functions.
