Wafer Internal Inspection System "INSPECTRA® IR" Series

Detects defects inside wafers using infrared light

Wafer internal defect inspection system "INSPECTRA® IR" series

Overview

An infrared internal defect inspection system has been added to the INSPECTRA® series.It is now possible to inspection with both infrared and visual light in one system.

Features

  • Uses a high-sensitivity camera and newly developed optical system, supporting both infrared and visible light, to rapidly detect internal defects in wafers
  • Uses tried and proved quality product learning algorithm to detect minute defects with a high degree of sensitivity
  • Inspection can be performed using both infrared and visible light(Switchable). Meets a wide range of inspection needs

Application examples

  • Defect inspection in Si capped structure MEMS wafers
  • Internal defect inspection in Image Senser
  • Void inspection in bonded wafers
  • Defect inspection in high aspect ratio trenches
  • Backside crack inspection in High-density wafer
