Substrate processing apparatus and substrate processing method

An underlayer is formed to cover the upper surface of a substrate and a guide pattern is formed on the underlayer. A DSA film constituted by two types of polymers is formed in a region on the underlayer where the guide pattern is not formed. Thermal processing is performed while a solvent is supplied to the DSA film on the substrate. Thus, a microphase separation of the DSA film occurs. As a result, patterns made of the one polymer and patterns made of another polymer are formed. Exposure processing and development processing are performed in this order on the DSA film after the microphase separation such that the patterns made of another polymer are removed.

Hydroxyl group termination for nucleation of a dielectric metallic oxide

A surface of a semiconductor-containing dielectric material/oxynitride/nitride is treated with a basic solution in order to provide hydroxyl group termination of the surface. A dielectric metal oxide is subsequently deposited by atomic layer deposition. The hydroxyl group termination provides a uniform surface condition that facilitates nucleation and deposition of the dielectric metal oxide, and reduces interfacial defects between the oxide and the dielectric metal oxide. Further, treatment with the basic solution removes more oxide from a surface of a silicon germanium alloy with a greater atomic concentration of germanium, thereby reducing a differential in the total thickness of the combination of the oxide and the dielectric metal oxide across surfaces with different germanium concentrations.
