Anti-reflective coating conformality control
Abstract:
A method for forming an anti-reflective coating on a semiconductor substrate, including providing a first vessel containing an anti-reflective coating component and a second vessel containing a solvent. The anti-reflective coating component from the first vessel and the solvent from the second vessel are supplied to a mixing chamber. The anti-reflective coating component and the solvent are mixed in the mixing chamber to form a product. The product is transferred to the semiconductor substrate. The product is applied to the semiconductor substrate to form the anti-reflective coating. A system for forming an anti-reflective coating on a semiconductor substrate, including a first vessel for containing an anti-reflective coating component and a second vessel for containing a solvent. The system also includes a mixing chamber for mixing the anti-reflective coating component with the solvent to form a product, and a fluid transport system connecting the mixing chamber and the substrate for supplying the product from the mixing chamber to the semiconductor substrate to form the anti-reflective coating.
