PRODUCT OVERVIEW
WAFER LEVEL OPTICAL CHARACTERISTIC MEASUREMENT SYSTEM FOR VCSEL(LIGHT EMITTING DEVICE)

Wafer Level Optical Characteristic Measurement System For VCSEL (Light Emitting Device) is to test various optical characteristics of light emittimg devices such as VCSEL, etc. under wafer level. In addition to the electrical characteristics measurement, optical characteristics, such as NFP, FFP, IVL, polarization, etc, can be measured under wafer level.

By combining prober systems for semiconductor failure analysis, such as semi-automatic/manual probers, with our Sophisticated Optical Measurement Optics For Prober M-Scope I/PFW, FFP Measurement Optics M-Scope type F, IVL Measurement Module PMD002/IVL, Polarization Measurement Module PMD002/POL, etc., various characteristics are measured under wafer level. In addition, it can be used for automatic measurement of mass-produced devices in combination with the semi-automatic prober system.

FEATURE

  • Wafer level electrical and optical testing of various light emitting devices such as VCSEL in combination with manual/semi-automatic prober system
  • Achieves automation, speedup, and efficiency of various types of measurements through the function of linking with Form Factor's semi-auto prober system.
  • Synos’ M-Scope series optics such as Sophisticated Optical Measurement Optics For Prober M-Scope I/PFW, FFP Measurement Optics M-Scope type F, IVL Measurement Module PMD002/IVL, Polarization Measurement Module PMD002/POL, etc., can be equipped. Optical system selection and system upgrade are possible according to the measurement item.
  • Synos’ optical measurement and analysis software, Optometrics Customised Version For LD, is equipped.
    • Various functions such as control of semi-automatic probe station, collection and management of optical and electrical analysis data acquired by Synos’ optical system and various measurement system, management of sample data and measurement recipe etc. are installed. It is available to both mass-production measurement and discrete measurement.

APPLICATION

  • Optical and electrical characteristic analysis of various light emitting devices such as VCSEL, etc. on wafer level
    • I-V-L characteristics, beam profile (NFP/FFP) analysis, polarization characteristic, emission spectrum measurement, etc.
