  • Patent number: 7322756
    Abstract: A coating and developing apparatus comprises a process block which forms a resist film on a wafer, then transfers the wafer to an exposure apparatus, and performs a developing process on the wafer after exposure, and an interface transfer mechanism provided between the process block and the exposure apparatus. The process block includes unit blocks for coating-film formation and unit blocks for development laid out in a stacked manner. When an abnormality occurs in the interface transfer mechanism, an ordinary process in the unit block for coating-film formation is performed on those substrates which are present in that unit block for coating-film formation, after which processed wafers are retreated to a retaining unit and transfer of any wafer into the unit block for coating-film formation is inhibited.

  • Patent number: 7281869
    Abstract: A coating and developing system includes a resist film forming unit block and antireflection film forming unit blocks stacked up in layers to form a resist film and an antireflection film underlying the resist film and an antireflection film overlying the resist film in a small space. The coating and developing system can cope with a case where antireflection films are formed and a case where any antireflection film is not formed. Film forming unit blocks, namely, a TCT layer, a COT layer and a BCT layer, and developing unit blocks, namely, DEV layers, are stacked up in layers in a processing block. The TCT layer, the COT layer and the BCT layer are used selectively in the case where antireflection films are formed and where no antireflection film is formed. The coating and developing system is controlled by a simple carrying program.

  • Patent number: 7262829
    Abstract: A coating and developing apparatus includes a process block which includes a unit block for coating-film formation which applies a resist, and a unit block for development which performs a developing process, and is separately provided with a coating-film-formation-unit-block transfer mechanism and a developing-process-unit-block transfer mechanism. After a substrate after exposure is transferred to a transfer stage from the interface-block transfer mechanism, the timing for the developing-process-unit-block transfer mechanism to receive the substrate is adjusted in such a way that the time from exposure of the substrate to transfer of the substrate to a heating unit becomes a preset time.

A direct carrying means is superposed on the coating block and the developing block to carry a substrate having a surface coated with a film from the carrier handling block directly to the interface block. A test substrate can be carried to the exposure system to inspect the condition of the exposure system even in a state where the coating block and the developing block are under maintenance work.
