WaferX 310
In-Line, Simultaneous WDXRF Spectrometer
Film thickness and composition measurements on blanket wafers
Rigaku's WaferX 310 represents the culmination of more than 40 years of experience in the X-ray fluorescence analysis of thin films on silicon wafers. Developed as an in-line metrology tool, it is ideally suited to 300 mm high-volume manufacturing environments.

WaferX 310 Overview
Simultaneous thickness and composition
The WaferX 310 is ideal for measuring BPSG, PSG and metal films. In addition, thin film BPSG, multilayered circuit film, WSix, electrode films, ferrodielectric thin films, FRAM, next generation DRAM, and SiOF are standard applications for this tool.
Analysis to support sub-micron technology
Highly accurate analyses for the ultralight elements such as B and P in BPSG film has been improved significantly by employing a 4kW high power X-ray tube with a super thin window beryllium window.
Advanced design
The instrument employs a wafer height adjustment mechanism to compensate for differences in wafer thickness and a diffraction avoidance mechanism to eliminate diffraction interference for the transition metals. Integrated FOUP(SMIF) is available, supporting the C-to-C standard. Various user cassettes can also be loaded. FOUP(SMIF) through-the-wall option is available.
Software redesign
- 3D graphics display enables the operator to judge status clearly
- The alarm position is displayed graphically, and accurate maintenance information is provided to the operator.
- “Bubble chart” display enables the operator to easily judge the distribution of intensity on a wafer.
- More flexible parameter setting to avoid X-ray diffraction effects.
