Substrate Processing Method and Substrate Processing Apparatus
A substrate processing method includes: forming a coating film so as to cover a front surface of the substrate, the substrate having a recess formed in the front surface and in which an organic film is formed; heating the substrate to turn the organic film into a gas, removing the gas from an interior of the recess by causing the gas to pass through the coating film, and forming in the substrate a sealed space surrounded by the recess and the coating film; supplying a processing gas into the sealed space; and irradiating the substrate with a light to activate the processing gas in the sealed space, causing a reaction product gas to pass through the coating film, and removing the reaction product gas, wherein the reaction product gas is generated by a reaction between a residue of the organic film and the activated processing gas in the sealed space.
Method and apparatus for coating selected regions of a substrate with a film
Method and apparatus for coating selected regions of a surface of a substrate with a film are disclosed. A cyclically moveable transfer member has an imaging surface which is coated with individual particles formed of, or coated with a thermoplastic polymer, and substantially all particles that are not in direct contact with the imaging surface are removed so as to leave a uniform monolayer particle coating on the imaging surface. Selected regions of the imaging surface are exposed to radiation to render the particles tacky within the regions, and the coated imaging surface and the substrate are pressed against one another to cause transfer of only the particles rendered tacky in the coating, such that the transferred particles form a film on the substrate. The monolayer on the imaging surface of the transfer member is replenished with fresh thermoplastic particles and the cycle repeats.
