Hi Bob, Could you please elaborate more on how you achieved successful pattern transfer without using a post exposure bake? The post expsure bake is required to cross-link exposed areas of the SU8. If you omit this step then surely at the development stage your SU8 will simply wash off? If you have found some way of using SU8 as a hard mask without the need for a post exposure bake then that would be something....
