What it is

The YES 1518SM is a thermal processing tool in the diffusion class.[3]

The YES 1518SM is used for Vapor Prime, Image Reversal, and Silylation.[3][1]

How it works

The YES 1518SM operates as a Vapor Prime, Image Reversal, and Silylation system.[3][1]

The YES 1518SM is specified with a maximum temperature stability of 160°C ± 2°C.[3][1]

Where it fits in the process flow

The YES 1518SM provides above-listed Vapor Prime and Image Reversal capacities, or Silylation on 4 cassettes of 5 or 6-inch wafers or 6 cassettes of 4-inch wafers.[3][1]

The YES 1518SM has a throughput of 2 full loads per hour.[3][1]

Applications

The YES 1518SM is used for Vapor Prime, Image Reversal, and Silylation.[3][1]

The YES 1518SM uses HMDS at less than 7 ml per 200 wafers.[3][1]
