J A Woollam Spectroscopic Ellipsometers

In-Situ Ellipsometry

In Situ Spectroscopic Ellipsometry (SE) measures a sample “in position” as conditions are varied. This includes measurements during film growth or removal; during variation in temperature, humidity, or other environmental conditions; and during other external stimulation of the sample (magnetic, electric).

In Situ SE is routinely used to monitor growth or etch of a thin film and can be implemented for real-time feedback control.  It is also common to use in situ measurements to characterise optical constants during different process conditions.

  • Models

    M2000

    The M-2000 line of spectroscopic ellipsometers is engineered to meet the diverse demands of thin film characterisation. An advanced optical design, wide spectral range, and fast data acquisition combine in an extremely powerful and versatile tool. 

    M-2000 delivers both speed and accuracy.  J A Woollam’s patented RCE technology combines Rotating Compensator Ellipsometry with high-speed CCD detection to collect the entire spectrum (hundreds of wavelengths) in a fraction of a second with a wide array of configurations. 

    M-2000 is the first ellipsometer to truly excel at everything from in-situ monitoring and process control to large-area uniformity mapping and general purpose thin film characterisation. No other ellipsometer technology acquires a full spectrum faster.

     

    Wide Spectral Range

    Collect over 700 wavelengths from the ultraviolet to the near infrared – all simultaneously.

     

    Flexible System Integration

    With modular optical design, the M-2000 is suited for direct attachment to your process chamber or configured on any of Woollam’s table-top bases.

     

    Accuracy

    Advanced design ensures accurate ellipsometry measurements for any sample.

    RC2

    The RC2 design builds on 25 years of experience. It combines the best features of previous models with innovative new technology: dual rotating compensators, achromatic compensator design, advanced light source and next-generation spectrometer design. The RC2 is a near-universal solution for the diverse applications of spectroscopic ellipsometry.

     

    Wide Spectral Range

    Collect over 1000 wavelengths from the ultraviolet to the near infrared, all simultaneously.

     

    Fast Measurement Speed

    Synchronous operation of both compensators allows highly accurate data without waiting to “zone-average” over optical elements. Collect the entire spectrum (over 1000 wavelengths) simultaneously in a fraction of a second.

    iSE

    J A Woollam have developed a new ellipsometer developed specifically for in-situ monitoring of thickness and optical properties.

     

    Powerful

    Determine thickness and optical constants with high certainty with Woollam’s proven spectroscopic ellipsometry including advanced data analysis capability, gives you thickness and optical properties with much higher certainty than other techniques.

     

    Compact

    New compact design enables easy integration onto any ALD chamber.

     

    Flexible

    Measure any kind of material-dielectrics, metals, metal oxides and more.

     

    Affordable

    The power of spectroscopic ellipsometry at a reasonable price.

     

    Ease-of-Use

    User friendly interface for real time data analysis and easy chamber integration.

     

    Fast, Wide-Spectrum Measurements

    While others claim fast measurements, only J.A Woollam ellipsometers provide fast, spectroscopic data over a wide wavelength range. The iSE utilizes a new optical design with Dual-Rotation™ in combination with modern CCD detection to provide hundreds of wavelengths in a fraction of a second.
