Patent JP-2002214802-A (JP)
Title: Method for producing semiconductor device
Inventor: HIRUMA KENJI
IPC: G03F7/38
Filed: 2001-01-12
Abstract: PROBLEM TO BE SOLVED: To prevent the dimensional change of a resist pattern formed through photolithography. SOLUTION: In the method for producing a semiconductor device with a coating step, in which an object is coated with a photoresist and an exposure- development step in which the photoresist is patternwise exposed and developed to form a resist pattern, prebaking is not carried out or prebaking at a low temperature is carried out in the coating step, and prebaking is carried out in the beginning of the exposure-development step. The exposure-development step thus follows the prebaking in a short time and the change of the resist pattern can be reduced. Since the time from prebaking to exposure is made fixed, dimensional errors among lots or between wafers in the same lot can be diminished.
