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 processing block for liquid immersion exposure processing, and an interface block. An exposure device is arranged adjacent to the interface block. The processing block for liquid immersion exposure processing comprises a coating processing group for resist cover film and a removal processing group for resist cover film. The resist cover film is formed in the processing block for liquid immersion exposure processing before the exposure processing. The resist cover film is removed in the processing block for liquid immersion exposure processing after the exposure processing.

Claims (41)

1. A substrate processing apparatus that is arranged adjacent to an exposure device that applies exposure processing to a substrate by a liquid immersion method, 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 processing section comprises:

a first processing block that includes a photosensitive film forming unit that forms a photosensitive film made of a photosensitive material on the substrate, 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 a development processing unit that applies development processing to the substrate after the exposure processing by said exposure device, a second thermal processing unit that thermally treats the substrate, and a second transport unit that transports the substrate;

a third processing block that includes a washing processing unit that supplies pure water onto said photosensitive film and washes the substrate after the formation of said photosensitive film by said photosensitive film forming unit and before the exposure processing by said exposure device, and a third transport unit that transports the substrate, and wherein

said third processing block is arranged adjacent to said interface.

2. The substrate processing apparatus according to claim 1 , wherein

said interface includes:

an edge exposure processing unit that applies an edge exposure processing to the substrate;

a platform on which the substrate is temporarily mounted;

a fourth transport unit that transports the substrate between said processing section, said edge exposure processing unit, and said platform; and

a fifth transport unit that transports the substrate between said platform and said exposure device.

3. The substrate processing apparatus according to claim 2 , wherein

said fourth transport unit includes first and second holders for holding the substrate, said fourth transport unit holds the substrate with said first holder during the transport of the substrate before the exposure processing by said exposure device, and holds the substrate with said second holder during the transport of the substrate after the exposure processing by said exposure device,

said fifth transport unit includes third and fourth holders for holding the substrate, and

said fifth transport unit holds the substrate with said third holder during the transport of the substrate before the exposure processing by said exposure device, and holds the substrate with said fourth holder during the transport of the substrate after the exposure processing by said exposure device.

4. The substrate processing apparatus according to claim 3 wherein

said second holder is provided below said first holder, and said fourth holder is provided below said third holder.

5. The substrate processing apparatus according to claim 1 , wherein

said third processing block further includes a drying processing unit that dries the substrate after the exposure processing by said exposure device.

6. The substrate processing apparatus according to claim 5 , wherein

said drying processing unit further washes the substrate before drying the substrate.

7. The substrate processing apparatus according to claim 5 , wherein

said interface includes:

a substrate processing unit that applies given processing to the substrate;

a platform on which the substrate is temporarily mounted;

a fourth transport unit that transports the substrate between said processing section, said substrate processing unit, and said platform; and

a fifth transport unit that transports the substrate between said platform, said exposure device and said drying processing unit.

8. The substrate processing apparatus according to claim 7 , wherein

said fifth transport unit includes third and fourth holders for holding the substrate,

said fifth transport unit holds the substrate with said third holder during the transport of the substrate from said platform to said exposure device and from said drying processing unit to said platform, and holds the substrate with said fourth holder during the transport of the substrate from said exposure device to said drying processing unit.

9. The substrate processing apparatus according to claim 8 , wherein

said fourth holder is provided below said third holder.

10. The substrate processing apparatus according to claim 1 , wherein

said washing processing unit further dries the substrate after washing the substrate.

11. The substrate processing apparatus according to claim 1 , wherein

said processing section further comprises a fourth processing block that includes an anti-reflective film forming unit that forms an anti-reflecting film on the substrate before the formation of said photosensitive film by said photosensitive film forming unit, a fourth thermal processing unit that thermally treats the substrate, and a sixth transport unit that transports the substrate.

12. The substrate processing apparatus according to claim 11 , further comprising an indexer that is arranged adjacent to another and of said processing section and carries in the substrate to said processing section and carries out the substrate from said processing section, wherein

said fourth processing block is arranged adjacent to said indexer.
