Abstract: A method of removing photoresist or redeposited material from a substrate or other surface using a carbon dioxide jet spray. A substrate having photoresist or redeposited material on its surface is disposed in an environmental enclosure. A carbon dioxide jet spray is generated and directed onto the surface of the substrate and photoresist or redeposited material. The carbon dioxide jet spray cools or freezes the material and causes a mismatch in the thermal coefficient of expansion of the material and the substrate. The material debonds from the substrate due to the induced thermal shock to the material. This rapid shrinkage loosens the material and allows the solid particles in the spray to knock the material from the surface of the substrate. The removed photoresist or redeposited material may be collected in a filter, and removed.
