Abstract
A substrate processing apparatus comprises an indexer block, an anti-reflection film processing block, a resist film processing block, a development processing block, a resist cover film processing block, a resist cover film removal block, and an interface block. An exposure device is arranged adjacent to the interface block. A resist film is formed on a substrate in the resist film processing block. A resist cover film is formed on the resist film in the resist cover film processing block before the substrate is subjected to exposure processing by the exposure device.
Claims10
A substrate processing apparatus that is arranged adjacent to an exposure device, comprising:
- a processing section for applying processing to a substrate;
- and
- an interface that is provided on one end of said processing section for exchanging the substrate between said processing section and said exposure device, wherein
- said interface includes a transport device that transports the substrate between said processing device, and
- said processing section includes:
- a first processing unit that forms a photosensitive film made of a photosensitive material on the substrate;
- a second processing unit that forms a protective film for protecting said photosensitive film on the substrate before exposure processing by said exposure device;
- a third processing unit that applies development processing to the substrate after the exposure processing by said exposure device;
- a first processing block that includes said first processing unit, a first thermal processing unit that thermally treats the substrate, and a first transport unit that transports the substrate;
- a second processing block that includes said second processing unit, a second thermal processing unit that thermally treats the substrate, and a second transport unit that transports the substrate;
- and
- a third processing block that includes said third processing unit, a third thermal processing unit that thermally treats the substrate, and a third transport unit that transports the substrate;
- and
- said transport device includes a transport mechanism configured to receive the substrate from and transfer the substrate to said exposure device, wherein
- said transport mechanism has a first holder configured to hold and transport the substrate before the exposure processing by said exposure device, and a second holder configured to hold and transport the substrate after the exposure processing by said exposure device, and
- said second holder is provided below said first holder.
A substrate processing method for processing a substrate in a substrate processing apparatus that is arranged adjacent to an exposure device, and comprises a first processing unit, a second processing unit, a third processing unit, and a fourth processing unit, the method comprising the steps of:
- forming a photosensitive film made of a photosensitive material on the substrate by said first processing unit before exposure processing by said exposure device;
- forming a protective film for protecting said photosensitive film on the substrate by said second processing unit before the exposure processing by said exposure device;
- holding the substrate before the exposure processing by said exposure device by a first holder of a transport mechanism to transport the substrate to said exposure device;
- holding the substrate after the exposure processing by said exposure device by a second holder provided below said first holder of said transport mechanism, to transport the substrate from said exposure device;
- applying development processing to the substrate by said third processing unit after the exposure processing by said exposure device;
- and
- removing said protective film by said fourth processing unit after the exposure processing by said exposure device and before the development processing by said third processing unit.
