    摘要: A negative resist composition is provided which comprises at least a constituent component which has a vinyl ether structure protected with an acetal in a molecule thereof. In the formation of negative resist patterns, an aqueous basic solution can be used without swelling. A process is also provided for forming a resist pattern, which comprises the steps of: applying a negative resist composition comprising at least a constituent component which has a vinyl ether structure protected with an acetal in a molecule thereof, on a to-be-treated substrate; selectively exposing the formed resist film to imaging radiation capable of provoking decomposition of a photo acid generator of the resist composition, and developing the exposed resist film with an aqueous basic solution. A process is also provided for manufacturing an electronic device, which comprises the step of selectively removing an underlying to-be-treated substrate using a resist pattern, formed from the above-mentioned process, as a masking means to form a predetermined functional element layer.
