Separation system, separation method, program and computer storage medium

1. A separation system separating a superposed substrate in which a processing target substrate and a supporting substrate are joined together with an adhesive into the processing target substrate and the supporting substrate, said separation system comprising:

a separation processing station performing predetermined processing on the processing target substrate, the supporting substrate, and the superposed substrate;

a transfer station transferring the processing target substrate, the supporting substrate or the superposed substrate with respect to said separation processing station;

a transfer unit transferring the processing target substrate, the supporting substrate or the superposed substrate between said separation processing station and said transfer station; and

an interface station configured to transfer the processing target substrate between said separation processing station and a post-processing station configured to perform a predetermined post-processing on the processing target substrate separated in said separation processing station,

wherein said separation processing station comprises:

a separation unit configured to separate the superposed substrate into the processing target substrate and the supporting substrate each held by a first holding part and a second holding part, respectively, the second holding part being configured to move both in a vertical direction and a horizontal direction with respect to the first holding part such that the second holding part is completely separated so as to be spaced apart from the first holding part in an obliquely downward direction, the first holding part having a main body part in a flat plate shape, and a porous body being provided on a lower surface side of the main body with a suction space provided above the porous body and connected to a suction pipe and being abutment with an entire top surface of the processing target substrate;

a first cleaning unit configured to clean the processing target substrate separated in said separation unit; and

a second cleaning unit configured to clean the supporting substrate separated in said separation unit,

wherein said transfer station is configured such that a superposed substrate including a normal processing target substrate determined to be normal by an inspection process and a superposed substrate including a defective processing target substrate determined to be defective by the inspection process are transferred into said transfer station, and

wherein said separation system further comprises a control unit configured to control said interface station and said transfer unit such that a normal processing target substrate is transferred to said post-processing station after being cleaned in said first cleaning unit and the defective processing target substrate is transferred to said transfer station after being cleaned in said first cleaning unit.

2. The separation system as set forth in claim 1 , further comprising:

an inspection unit provided between said separation processing station and said post-processing station for inspecting the processing target substrate.

3. The separation system as set forth in claim 1 ,

wherein said interface station comprises another transfer unit including a Bernoulli chuck or a porous chuck holding the processing target substrate.

4. The separation system as set forth in claim 1 ,

wherein said first holding part includes a heating mechanism heating the processing target substrate,

said second holding part includes a heating mechanism heating the supporting substrate, and

said separation unit includes a moving mechanism moving at least said first holding part or said second holding part relatively in a horizontal direction.

5. The separation system as set forth in claim 4 ,

wherein said moving mechanism moves at least said first holding part or said second holding part relatively in a vertical direction.

6. The separation system as set forth in claim 1 ,

wherein said separation processing station comprises another transfer unit transferring the processing target substrate held by a Bernoulli chuck thereof between said separation unit and said first cleaning unit.

7. The separation system as set forth in claim 1 ,

wherein said first cleaning unit includes a porous chuck holding the processing target substrate.
