  • Patent number: 11676834
    Abstract: In substrate processing, by supplying a first processing liquid onto an upper surface 91 of a substrate 9 held in a horizontal state, a liquid film 81 of the first processing liquid which entirely covers the upper surface 91 is formed. Further, by heating the substrate 9, a vapor layer 82 of the first processing liquid is formed between the upper surface 91 and the liquid film 81 of the first processing liquid on the upper surface 91. Then, by supplying a second processing liquid onto the upper surface 91 of the substrate 9, the liquid film 81 of the first processing liquid is removed from the upper surface 91. It is thereby possible to appropriately remove extraneous matters 89 from the upper surface 91 of the substrate 9, which are taken in the liquid film 81 of the first processing liquid as the vapor layer 82 is formed.

  • Patent number: 11152204
    Abstract: A substrate processing method includes an intermediate processing step of processing the pattern forming surface by the intermediate processing liquid after a chemical liquid processing step, a filler discharging step of discharging a filler after the intermediate processing step, a filler spreading step of spreading the filler, a solidified film forming step of solidifying the filler, a lower position disposing step of making a blocking member be disposed at a lower position prior to start of the chemical liquid processing step, and a blocking member elevating step of starting elevation of the blocking member toward an upper position in a state where the pattern forming surface is covered with the intermediate processing liquid. The chemical liquid is discharged from a central nozzle. Spreading of the filler is started in a state where the blocking member is positioned at the upper position.
