IEC 60747-18-3:2019

Overview

IEC 60747-18-3:2019 - "Semiconductor devices - Part 18-3: Semiconductor bio sensors - Fluid flow characteristics of lens-free CMOS photonic array sensor package modules with fluidic system" - defines standardized methods for characterizing fluid flow in lens-free CMOS photonic array sensor package modules used for bio analysis. The standard specifies the measurement setup, initial-state and steady-state flow measurement and calculation methods, criteria for quality assurance, calibration procedures, and the required content of the test report.

Key topics and technical requirements

• Measurement setup and system requirements
  • Defined measurement configuration for lens-free CMOS photonic array sensors integrated with a fluidic system, including photoelectric measurement schematics and sensor parameters.
• Initial-state flow measurement and calculation
  • Procedures to capture and analyze flow propagation profiles during early, intermediate and final stages of flow introduction.
  • Methods to calculate horizontal and vertical flow velocities for both global shutter and rolling shutter sensor readout modes.
• Steady-state flow analysis
  • Measurement and calculation methods covering all pixels at every frame to assess uniformity and stability of the fluidic environment over time.
• Calibration and planarization
  • Calibration procedures to correct non-uniformities in the fluidic system and sensor response, including final evaluation of calibrated modules.
• Quality assurance criteria
  • Defined pass/fail criteria and statistical evaluation approaches (e.g., per-column and full-frame analysis) to ensure reproducible fluidic performance.
• Test reporting
  • Required contents for a test report documenting setup, measurement parameters, calculations, calibration, and evaluation results.
• Terminology and fluid dynamics context
  • Includes relevant definitions such as Reynolds number and linearity for accurate interpretation of flow behavior.

Practical applications and who uses this standard

IEC 60747-18-3 is directly applicable to:

• Semiconductor and sensor manufacturers developing lens-free CMOS photonic array sensor modules with integrated microfluidics.
• Medical device and diagnostics companies using lens-free sensors for point-of-care, patchable, implantable, or lab-on-chip bio-analytical devices.
• Test laboratories and QA teams validating fluidic performance, repeatability, and conformance to product specifications.
• R&D teams optimizing fluid delivery, sensor calibration, and imaging protocols in lens-free microscopes and biosensing platforms.

Practical uses include characterizing flow propagation in porous media, verifying uniform sample delivery for bioassays, and ensuring sensor-module reliability in healthcare and diagnostic products.
