iFOX – wafer inspection system

Microelectronics processes are becoming denser, with more layers, and more complicated.
Mass production of WAFERS requires high-speed scanning systems capable of detecting defects on high-density printed layers.
Nextec’s advanced iFOX Wafer Inspection machine has been designed to fulfill the evolving market demands through the following capabilities:

  • Scanning using advanced technology & precise mechanics for ultra-fast scanning with minimum aberration
  • Advanced defect inspection technology using a Large-field 2D microscope with a superior illumination system & focus-on-the-fly technology
  • Advanced 3D Bump inspection using patented 3D structure light microscope

Unlike our competitors, we provide a software package that is used to create measurement plans so that customers can build any measurement plan necessary.

2D capabilities

  • Defect finding down to 0.5 microns.
  • Masks allow customers to choose different inspection parameters for different areas on the die.
  • Advanced inspection algorithm to support large process variation.
  • Fast algorithm implementation running on several GPUs boards and multiprocessing.

3D bump inspection capabilities

  • Bump Height – using structure light technology for improved productivity and measurements accuracy.
  • Inspection of millions of bumps at very high speed.
  • Provides co-planarity data for each die and for all wafers.

Metrology capabilities

The metrology package provides a reach measurement tool library that creates a complicate metrology recipe in a seconds:

This results in a comprehensive inspection solution ofering the folowing:
