Abstract:
1. A developing apparatus comprising: a rotatable spin chuck configured to hold a substrate having a light-exposed resist film disposed thereon; a developing solution/chemical liquid supply nozzle configured to mix a developing solution and a chemical liquid at a predetermined ratio to form a mixture liquid, and supply the mixture liquid onto a surface of the substrate held by the spin chuck, wherein the chemical liquid contains a resist curing aid contributory to curing of a resist film remaining on the substrate after a developing reaction; a rinsing nozzle configured to supply a rinsing liquid onto a surface of the substrate held by the spin chuck; a shifting mechanism configured to move the developing solution/chemical liquid supply nozzle and the rinsing nozzle relative to the substrate held by the spin chuck; and a light radiation mechanism configured to radiate light having a predetermined wavelength onto a surface of the substrate held by the spin chuck, wherein the developing solution/chemical liquid supply nozzle comprises a casing elongated in one direction and having therein a first liquid reservoir cell to store the developing solution, a second liquid reservoir cell to store the chemical liquid, and a liquid mixing cell communicating with the first liquid reservoir cell and the second liquid reservoir cell, all of which extend in a longitudinal direction of the casing, wherein the liquid mixing cell has a discharge port at a lower end to discharge a mixture liquid essentially as a strip, and the mixture liquid comprises the developing solution and the chemical liquid mixed at a predetermined ratio, the light radiation mechanism comprises a casing elongated in one direction and having a slit to radiate light essentially as a strip extending in a longitudinal direction thereof, and a light source of a predetermined wavelength disposed in the casing, and the casing of the developing solution/chemical liquid supply nozzle and the casing of the light radiation mechanism are integrated in parallel with each other.
