Step Height

The Tencor P-7 benchtop stylus profiler is capable of measuring 2D and 3D step heights from nanometers to 1000?m. This enables quantification of material deposited or removed during etch, sputter, SIMS, deposition, spin coating, CMP and other processes. The Tencor P-7 profilometer has constant force control that dynamically adjusts to apply the same force on the sample surface, regardless of step height. This results in good measurement stability and enables accurate measurement of soft materials, such as photoresist.

Texture: Roughness and Waviness

The Tencor P-7 profilometer measures 2D and 3D texture, quantifying the sample’s roughness and waviness. Software filters separate the measurement into the roughness and waviness components and calculate parameters, such as the root mean square (RMS) roughness.

Form: Bow and Shape

The Tencor P-7 can measure the 2D shape or bow of a surface. This includes measurement of wafer bow that can result from mismatch between layers during device fabrication, such as deposition of multiple layers for the production of semiconductor or compound semiconductor devices. The Tencor P-7 benchtop profiler can also quantify the height and radius of curvature of structures, such as a lens.

Stress: 2D and 3D Thin Film Stress

The Tencor P-7 profilometer is capable of measuring stress induced during the manufacture of devices with multiple process layers, such as semiconductor or compound semiconductor devices. The bow of the surface is accurately measured using a stress chuck to support the sample in a neutral position. The change in shape from a process, such as film deposition, is then used to calculate the stress by applying Stoney’s equation. 2D stress is measured with a single scan across the sample diameter for samples up to 200mm without the need to stitch. 3D stress is measured using a combination of 2D scans, with the theta stage rotating between scans to measure the full sample surface.

Defect Review

Defect Review is used to measure the topography of defects, such as the depth of a scratch. Defect inspection tools identify defects and write the location coordinates to a 桃汁影院RF file. The Defect Review feature reads the 桃汁影院RF file, aligns the sample, and allows the user to select defects for 2D or 3D measurement.

Stylus Options

The Tencor P-7 has a variety of styli available to support the measurement of step heights, high aspect ratio steps, roughness, sample bow, and stress. The tip radius ranges from 100nm to 50?m and determines the lateral resolution of the measurement. The included angle ranges from 20 to 100 degrees, which specifies the maximum aspect ratio of the measured feature. All styli are manufactured from diamond to reduce wear and increase stylus lifetime.

Sample Chucks

The Tencor P-7 has a range of chucks available to support application requirements. The standard is a universal vacuum chuck with precision locating pins for samples of 50 to 150mm. The universal chuck supports bow and stress measurements with 3-point locators to support the sample in a neutral position. Additional options for solar samples and 200mm universal chucks are available.

Isolation Tables

The Tencor P-7 has both tabletop and free-standing isolation table options. The Granite Isolator? Series offers tabletop systems that combine granite with high grade silicone gel to provide passive isolation. The Onyx Series tabletop isolation systems use pneumatic air isolators to provide passive isolation. The TMC 63-500 Series isolation table is a free-standing steel frame table that uses pneumatic air isolators to provide passive isolation.

Step Height Standards

The Tencor P-7 uses thin and thick film NIST-traceable step height standards offered by VLSI Standards. The standards feature an oxide step on a silicon die mounted on a quartz block, or an etched quartz step with a chrome coating. A step height range of 8nm to 250?m is available.

Apex Analysis Software

Apex analysis software enhances the standard data analysis capability of the Tencor P-7 with an extended suite of leveling, filtering, step height, roughness, and surface topography analysis techniques. Apex supports ISO roughness calculation methods, plus local standards, such as ASME. Apex can also serve as a report writing platform with the capability to add text, annotations, and pass/fail criteria. Apex is offered in eleven languages.

Offline Analysis Software

The Tencor P-7 offline software has the same data analysis and recipe creation capability that exists on the tool. This enables the user to create recipes and analyze data without using valuable tool time.

Pattern Recognition

Pattern recognition uses pre-taught patterns to automatically align the sample. This enables fully automated measurements for enhanced measurement stability by reducing the impact of operator error. Pattern recognition combined with advanced calibrations reduces stage positioning error and enables seamless transfer of recipes between systems.

SECS/GEM and HSMS

SECS/GEM and HSMS communications support factory automation systems and enable remote control of the Tencor P-7. Measurements results are automatically reported to host SPC systems, plus alarms and key calibration/configuration data. The Tencor P-7 is compliant with SEMI standards E4, E5, E30, and E37.
