GAERTNER ELLIPSOMETER PDF

It is a popular alternative to overly complicated ellipsometers for precise routine measurement. The laser light source has ample light intensity for increased measurement accuracy of absorbing and rough scattering films. Laser sources have the added advantage of being spectrally precise, stable and long lasting. Lasers permit optimum instrument design using optics, detectors and other components so that measurements can be made highly accurate. The sample stage can be locked in place or easily moved by hand to measure any point on the sample surface.

Unlike other ellipsometers, Stokes Elipsometers utilize the complete state of polarization of the measuring beam to provide exceptional accuracy and precision. They are a popular alternative to overly complicated spectroscopic ellipsometers at an affordabe price. Easy to use and affordably priced, the LSE-WS is a popular choice in a high precision scanning ellipsometer.

They give refractive index results in near period regions, and measure the thickness of thicker films, and offer many of the advantages of spectroscopic ellipsometers without the complexity and cost. The model LS maps up to mm wafers. Variable Angle Stokes Laser Ellipsometer LS The LS with a manual hand positioning stage makes measurements of film thickness and film refractive index in milliseconds. The variable angle capability determines thicker film thickness and gives refractive index measurements over a wider thickness range.

Pre-Owned Laser Ellipsometers are factory refurbished, upgraded and sold with a full 1 year warranty. A pre-owned ellipsometer available at a substantially lower price is a good option for a company or university on a limited budget.

Check availability on these value ellipsometers. NIST Traceable Calibration Standards for Ellipsometers are silicon wafers with a thermally grown silicon dioxide film which permit ellipsometers to be calibrated so they can operate in top condition.

Gaertner-Ellipsometer

Fenriran The light beam, the state of polarization of which is to be determined, strikes, at oblique angles of incidence, three photodetector surfaces in succession, each of which is partially ellipsojeter reflecting and each of which generates an electrical signal proportional to the fraction of the radiation it absorbs. A fourth photodetector is substantially totally light absorptive and detects the remainder of the light. This fact permits the film refractive index to be measured in addition to the film thickness. Accurate, stable measurements using spectrally precise laser source.

GAERTNER L116S300 STOKES ELLIPSOMETER

The easy to use model LS maps wafers up to mm in diameter and offers precise measurements at a cost much lower then conventional production control metrology systems. Measures complete state of polarization useful for rough,scattering samples. Accurate, stable measurements using spectrally precise laser source. Simple, compact tabletop instrument - competitively priced. From thin gate oxides only tens of angstroms thick to thick polyimides and photoresists Gaertner has earned a reputation for providing precise, reliable results. Single Layer films such as oxides, nitrides and photoresists can be measured to sub-angstrom precision. Two, three and four layer films, with know bottom layers such as poly on oxide and oxide on poly on oxide can be measured for the thickness and refractive index of the top layer or for both thicknesses.
