  • Bruker 3D Optical Profiler

    bruker-optical-profiler

    The Bruker ContourGT-I is a fully automated and programmable optical interferometric microscope that can be used to measure and map surface features in 3D. The system features an automated tip/tilt optical head, to enable measurements over a range of angles while minimizing tracking errors.

  • Bruker AFM

    bruker-afm

    The Dimension FastScan AFM provides high speed topographic imaging without loss of resolution or force control. The system is capable of measurements on both large and small size samples in air or fluids. The FastScan module generates on the fly atomic force microscopy images.

  • Bruker Stylus Profiler

    bruker-dektak

    The Bruker Dektak-XT is a semi-automated stylus profiler that can be used to measure step height with better than 5 Å repeatability, surface roughness, as well as 3D surface mapping.

  • FEI Scanning Electron Microscope

    fei-sem

    The Nova NanoSEM™ is a high resolution scanning electron microscope intended for sample characterization. In addition to the SEM features, the Nova system is configured with a beam blanker and the Raith ELPHY Quantum software to enable electron beam lithography for users who do not require the ultra-high resolution of the Elionix system.

  • Filmetrics

    filmetrics

    The Filmetrics F20 is used to measure the thickness and optical constants (n and k) of transparent and semi-transparent thin films. Measured films must be optically smooth and between 100Å and 50_m thick. Commonly measured films include semiconductor process films such as oxides, nitrides, resists and polysilicon. Films that cannot be measured include very rough films and opaque films.  The Filmetrics thin film analyzer is very useful for rapidly fine-tuning resist recipes and measuring etch rates.

  • J.A. Woollam V-Vase Ellipsometer

    vase-ellipsometer

    The Woollam V-VASE is a Variable Angle Spectroscopic Ellipsometer capable of automated thin-film characterization, high-precision angle, and a wide spectral range (240 nm to 2500 nm). Analysis of ellipsometric data can be used to determine layer thickness, surface and interfacial roughness, sample anisotropy, Mueller-matrix data, and optical constants (refractive index and extinction).The tool has a vertical sample vacuum mount that can accommodate up to 200 mm diameter samples.

    The V-VASE is configured with an automated z-translation stage and digital camera for spot location viewing. Focusing optics and provide the ability to reduce the beam spot size down to 100 or 200 _m, depending on fiber choice. A heating stage is also available for samples up to 50 mm in diameter and 7.6 mm-thick with temperatures ranging from room temperature to 300_C.

  • Nikon Inspection Microscope

    nikon-microscopes

    Several Nikon eclipse microscopes inspection microscopes are located throughout the cleanroom. The system has a 6”x6” stage and is configured with bright-field, dark-field, and simple polarizing objectives. The microscopes are fitted with a Nikon DigiSight Color Digital Camera Head (5 megapixels) and a PC with Nikon’s NIS-Elements software.
