SEMI T7 Data Matrix, SEMI T7-0302
Barcodesoft SEMI-T7 Data Matrix software is a smart and simple solution for back surface marking of double-side polished silicon wafers with a Data Matrix symbol.
Barcodesoft SEMI-T7 DataMatrix software is designed in compliance with SEMI T7-0302 standard, which specifies the location and dimension of Data Matrix code symbol.
All SEMI Data Matrix symbols have 8 rows by 32 columns. Symbol width is 1mm. Symbol height is 4mm.
The specification was approved by Global Traceability Committee and North American Traceability Committee.
Type in your 8-character vendor-assigned wafer ID and the 2-character vendor ID from Encoder, you will get SEMI Data Matrix symbol.
Two SEMI M12 check characters will be appended after your data automatically.
If you are using the Demo version, your data will be prefixed by "DEMO" watermark.
User can choose export image resolution: 300 , 600, 1200, and 2400 DPI.
User can choose export image format: PNG, JPeg, and SVG. In the demo version, export to SVG format option is disabled.
SEMI-T7 SVG images will need SVG viewer.
User can choose export folder. The default export folder is C:\Users\{UserName}\AppData.
User can choose between circle shape and square shape. Filled or not.
If you are using demo release, exported SEMI-T7 data matrix data will be prefixed by "DEMO".
After a valid license is typed in, demo watermark will be gone.
If you download and install the Barcodesoft SEMI-T7 software on your computer, you'll discover a Windows application named SemiT7CmdLine.
This application allows you to automatically create SEMI-T7 images.
SEMIT7CmdLine -l licensecode -s Square|Circle -i Yes|No -f png|jpeg|svg -r 300|600|1200|2400 -e C:\MyFolder -t 12345678AS
Even without a valid license code, it will still export SEMI-T7 image to your designated folder. However, it will add a "demo" watermark before your data.
Barcodesoft SEMI Data Matrix symbol has the following nominal dimensions:
