Abstract

According to one aspect of the present disclosure, a transport system includes a mobile cassette unit capable of storing a plurality of structures and supplying the structures to an inspection unit, wherein each of the structures includes a substrate on which a plurality of devices are formed, and an interconnect member including a contact section that electrically contacts an electrode of the plurality of devices.

Claims (32)

1. A transport system comprising:

a plurality of mobile cassette units capable of storing a plurality of structures and transferring the plurality of structures to a plurality of inspection units,

a management device configured to determine a destination for each of the plurality of mobile cassette units and cause the plurality of mobile cassette units to move to each determined destination, each determined destination being a place where one of the plurality of inspection units is located, and

a position measuring device configured to measure, for each of the plurality of mobile cassette units, a relative position of each of the plurality of mobile cassette units to each of the plurality of inspection units,

wherein the management device is configured to determine the destination based on the measured relative position,

wherein each of the plurality of structures includes

a substrate on which a plurality of devices are formed, and

an interconnect member including a contact section that electrically contacts an electrode of the plurality of devices.

2. The transport system according to claim 1 , wherein each of the mobile cassette units is an automated guided vehicle.

3. The transport system according to claim 1 , wherein the interconnect member is a probe card including a probe that contacts the electrode of the plurality devices.

4. The transport system according to claim 1 , wherein each of the plurality of mobile cassette units includes

a storage section configured to store the structure,

a transfer section configured to transfer the structure between the storage section and the inspection unit, and

a drive section configured to drive the mobile cassette unit.

5. The transport system according to claim 4 , wherein each of the plurality of mobile cassette unit includes a temperature control section configured to adjust a temperature of the structure stored in the storage section.

6. An inspection system comprising:

a plurality of inspection units; and

a plurality of mobile cassette units capable of storing a plurality of structures and transferring the plurality of structures to the plurality of inspection units,

a management device configured to determine a destination for each of the plurality of mobile cassette units and cause the plurality of mobile cassette units to move to each determined destination, each determined destination being a place where one of the plurality of inspection units is located, and

a position measuring device configured to measure, for each of the plurality of mobile cassette units, a relative position of each of the plurality of mobile cassette units to each of the plurality of inspection units,

wherein the management device is configured to determine the destination based on the measured relative position,

wherein each of the plurality of structures includes

a substrate on which a plurality of devices are formed, and

an interconnect member including a contact section that electrically contacts an electrode of the plurality of devices.

7. An inspection method comprising:

measuring, for each of a plurality of mobile cassette units, a relative position of each of the plurality of mobile cassette units to each of a plurality of inspection units,

determining a destination for each of the plurality of mobile cassette units based on the measured relative position, each determined destination being a place where one of the plurality of inspection units is located,

moving the plurality of mobile cassette units to the each determined destination,

transferring a plurality of structures stored in the plurality of mobile cassette units to the plurality of inspection units, and

inspecting a plurality of devices within the plurality of structures using the plurality of inspection units, wherein the plurality of structures is stored in the plurality of mobile cassette units by following steps:

a step of causing an electrode of the plurality of devices formed on a substrate and a contact section of an interconnect member provided corresponding to the electrode to contact to form a structure in which the substrate and the interconnect member are assembled, and

a step of storing the structure in each of the plurality of mobile cassette units.
