What it is

The Strasbaugh 70 R Edge is an edge grinding machine used in semiconductor manufacturing.[1][2]

The Strasbaugh 70 R Edge belongs to the dicing and grinding category of semiconductor processing equipment.[2]

How it works

The Strasbaugh 70 R Edge operates on three-phase electrical power at 208 volts.[1][2]

Where it fits in the process flow

General reference — not yet source-verified

In the semiconductor fabrication workflow, edge grinding is performed after wafer slicing from an ingot and before subsequent processes such as lapping, polishing, or lithography.

The edge grinding step removes saw marks, chips, and other irregularities from the wafer periphery, reducing the risk of crack propagation during later handling and processing.

Applications

General reference — not yet source-verified

Edge grinders like the Strasbaugh 70 R Edge are used in the production of semiconductor wafers for various device types, including memory, logic, and power devices.

The equipment is generally applied to silicon wafers, as well as other semiconductor substrate materials such as gallium arsenide, silicon carbide, and sapphire.
