SEMI T7 Data Matrix Back Surface Marking

Barcodesoft SEMI-T7 software provides a smart, automated solution for marking double-side polished silicon wafers. Fully compliant with SEMI T7-0302, it ensures precise traceability through high-resolution Data Matrix symbols.

Standard Compliance

Our software is designed in strict adherence to the SEMI T7-0302 standard, which governs the specific location and dimensions of Data Matrix code symbols on silicon wafers. This specification is approved by the Global Traceability Committee and the North American Traceability Committee.

Nominal Dimensions

Symbol Type Rows Columns Total Width Total Height
SEMI Data Matrix 8 32 1.0 mm 4.0 mm

Note: Symbols must be applied via laser scribing for compliance.

Encoding & Data Structure

To generate a valid symbol, input the following:

  • 1 Wafer ID: 8-character vendor-assigned ID.
