Patent ID: 6939206

Claim:
A substrate carrier that is capable of receiving a vacuum and holding a substrate from a backside for processing a frontside of the substrate, using a solution, the substrate carrier comprising: a base of the substrate carrier for placing the substrate thereon; a sealing member disposed on the base and defining an inner region of the base, the sealing member adapted to contact the backside of the substrate to thereby establish a backside inner region of the substrate, and assist in preventing the solution from reaching the backside inner region of the substrate during the processing of the substrate; and multiple sealing members disposed outside the sealing member and adapted to assist in preventing the solution from reaching the backside inner region of the substrate during the processing of the substrate, wherein the multiple sealing members include at least two outer sealing members, the at least two outer sealing members disposed outside of and around the scaling member and adapted to contact the backside of the substrate and thereby assist in preventing the solution from reaching the backside inner region of the substrate, wherein one or more of the at least two outer sealing members is an inflatable sealing member.
