SEMI PV32: Wafer Marking Specification

The SEMI PV32 specification, titled "Specification for Marking of PV Silicon Brick Face and PV Wafer Edge," is a vital tool for the photovoltaic industry. This standard addresses the critical need for unique identification of silicon wafers throughout the manufacturing process. By providing a means to mark each wafer with a distinctive pattern, the specification ensures traceability and quality control from the silicon brick stage to the final solar cell module. Key features of this specification include a

• brick slice code (BSC) applied through a laser scribing process
• mark stability throughout all manufacturing steps
• readability from both sides of the wafer

Technical Details and Specifications

The SEMI PV32 specification outlines the technical requirements for marking silicon wafers. The brick slice code (BSC) is a unique pattern of grooves applied to the polished side surface of a silicon brick. This pattern is then transferred to the individual wafers, ensuring that each wafer can be easily identified. The specification emphasizes the need for the mark to be stable and readable throughout the manufacturing process, without affecting the efficiency of the solar cells or increasing manufacturing costs.

• Marking process: Fast laser scribe
• Mark placement: Outside the active area of the solar cells
• Mark orientation: Independent of the wafer's positional orientation

Practical Applications and Benefits

The SEMI PV32 specification offers numerous benefits to the entire PV industry. By providing a unique wafer mark, it enhances product security, reduces the risk of fraud, theft, and counterfeiting. This standard is particularly useful for suppliers of silicon wafers and module manufacturers, as it streamlines the tracking and tracing of wafers. The availability of equipment for applying and reading marks further simplifies the process.

• Enhanced product security
• Streamlined tracking and tracing
• Reduced risk of fraud and counterfeiting

The SEMI PV32 specification is an essential tool for ensuring the quality and integrity of photovoltaic products.
