Title: Manufacture of semiconductor device
Inventor: AOKI HIROMITSU
IPC: H01L21/306
Filed: 1987-01-23
Abstract: PURPOSE:To form a gate metal of submicron at an opening part by forming an image reverse resist on a semiconductor substrate and the image reverse resist is heated for curing by exposing selectively its resist to UV rays and form the opening part having a state of undercut of submicron by development, thereby forming a conducting film of submicron only at the opening part after removing the image reverse resist. CONSTITUTION:An image reverse resist 2 that is in the form of diazonovolak is coated by rotating it on a gallium arsenide substrate 1 and it is pre-backed. A gate pattern is replicated to the resist 2 by exposing selectively. A diazoquinone-sensitive material is dissolved by over-exposing it through a UV irradiation and a resist part 3 that is soluble in alkali developer as well as an amine-type catalyst are formed. Then reversal bake is carried out and indene that is not soluble in alkali solution as well as the resist part 4 are formed by causing azide to react to the catalyzer. The resist that is not exposed yet is converted into soluble azide 3 by irradiating UV rays on the whole plane of the resist. Then a submicron pattern of undercut is formed by developing the azide 3. Subsequently, a gate metal 5 is vapor-deposited on the whole plane and the unnecessary gate metal is removed by dissolving the residual resist 4 by a solvent. Thus the gate metal 5 of submicron is formed on the substrate.
