SEMI OCR Font & SEMI M12/M13 Standardization
Barcodesoft’s SEMI font package is engineered for seamless compliance with global semiconductor manufacturing standards, providing high-reliability tracking across production environments. Approved by both the Global Traceability Committee and the North American Traceability Committee, the SEMI M12/M13-1103 standard defines the exact geometries and dimensions for 26 alphanumeric characters, 10 numerals, dashes, and periods.
By deploying this package alongside a standard Windows environment and a compatible laser scriber, manufacturers can precisely etch wafer identification data with the ease of standard document printing. Additionally, the font geometries are fully optimized to support high-accuracy Optical Character Recognition (OCR) software workflows.
Technical Specifications (At 12 pt. Font Size)
When rendered at a 12-point size, the Barcodesoft SEMI (OCR) font conforms to these precise nominal dimensions:
| Dimension Metric | Standard Value |
|---|---|
| Character Height | 1.624 mm |
| Character Width | 0.812 mm |
| Stroke Width | 0.200 mm |
| Character Spacing | 1.420 mm |
Software Package Components
The standard font package includes three distinct TrueType options to fit specific hardware configurations:
- BcsSEMI: A traditional TrueType vector outline font.
- SEMI-Single-Simple: A single-density dot-matrix font variant.
- SEMI-Double-Simple: A double-density dot-matrix font variant.
Automated Checksum Generation
To ensure data integrity, the package includes the SEMIChecksum Windows command-line utility, which automatically calculates mandatory string validation codes.
* Note: The M12 standard evaluates a strict 10-character string, while the M13 standard requires a 16-character string input. Evaluation versions of the downloadable font contain protective watermarks on select characters.
Why Upgrade to Wafer Marking Studio™?
Beyond a basic font: Industrial-grade reliability designed engineered for high-volume fabrication lines.
| Feature Capability | Standard Font Package | Wafer Marking Studio™ |
|---|---|---|
| Supported Dot Densities | Single (1x), Double (2x) | Single (1x), Double (2x), Triple (3x), Quadruple (4x) |
| Circle Geometric Accuracy | Standard Bézier curves with minor tolerance variances | Advanced rendering engine for mathematically perfect circles |
Surface Roughness Mitigation
Wafer backsides are unpolished and introduce severe background noise. The 4X Quadruple Density rendering creates robust, solid strokes that remain clear where standard 1X marks easily distort.
Mechanical Thinning Resilience
Backside grinding in modern 3D IC packaging easily erases shallow markings. High-overlap dot configurations guarantee that the wafer ID safely survives the entire aggressive thinning lifecycle.
Automated Traceability Insurance
In fully automated "Dark Fabs," a single "No-Read" error halts the entire processing line. Upgrading eliminates tracking blind spots, preventing costly production line stoppages and downstream bottlenecks.
