Assignee: APPLIED MATERIALS ITALIA S.R.L.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 4:
5. Method for aligning a solar cell element, comprising:
detecting information about a first position of the solar cell element on a carrying device;
adjusting an orientation of a transfer device based on the information about the first position; and
detecting information about an intermediate position of the solar cell element in relation to the transfer device, wherein
the information about the first position is detected by a first detection device,
the first detection device comprises a first and a second detection section placed at different sides of the carrying device, the first and second detection sections are configured as optical barriers, and
the first detection device is configured to cause the first detection section to detect presence of the solar cell element for a time range x, cause the second detection section to detect absence of the solar cell element for a time range y and then detect presence of the solar cell element, and compare the time range x and the time range y to determine an indicator for a degree of rotation of an orientation of the solar cell element in a plane parallel to a plane of the solar cell element.
