Overview
IEC 60747-18-2:2020 - part of the IEC 60747 semiconductor devices series - specifies the evaluation process for lens-free CMOS photonic array sensor package modules used in semiconductor bio‑sensors. The standard defines the measurement environment and setup, the stepwise test and calibration flow, statistical analysis of test data, and requirements for reporting test results. It covers assessment of sensor characteristics, spatial uniformity of user light, and the middle layer effect under various user light conditions, plus evaluation of calibrated modules and the required test report.
Key Topics and Requirements
- Measurement setup and environment: Defines standard conditions and measurement systems for reproducible photoelectric testing of lens‑free CMOS photonic array sensor package modules, including incident light geometry and sensor board configuration.
- Sensor characteristics: Procedures to measure photonic responsivity, linearity and related photoelectric parameters using the schematic measurement flows provided in the standard.
- Spatial uniformity of user light: Methods to assess uniformity of the first and second user light sources that illuminate the sensor, a critical factor for accurate lens‑free imaging.
- Middle layer effect: Evaluation steps for how intermediate packaging layers impact sensor response under collimated and user‑defined light conditions.
- Statistical analysis and representative outputs: Guidance on statistical treatment of test data to establish representative output values across the effective sensor area.
- Test report content: Mandatory inclusion of measurement system details, accuracy information, test conditions (temperature, wavelength, incident angle), and calibrated results.
- Normative references and diagrams: References IEC 60747-18-1 for calibration methods and includes measurement schematics and flow diagrams to guide test labs.
- IP considerations: The document notes that certain calibration and correction methods cited may be subject to patents (holder: SOL Inc.), and users should verify licensing requirements.
