Aqueous or water-based developers are used in the lithography process to pattern photoresist films immediately after the exposure process. For positive photoresists, the developer removes film in the exposed wafer regions to produce device patterns. For negative photoresists, the developer removes film in the unexposed wafer regions to produce device patterns.
