Overall Benefits:
- Easier testing of your SPM.
- Improved accuracy of critical dimension measurements.
- Accuracy: 0.5% (1 std. dev.).
Features and Benefits:
- Holographic fabrication - assures high accuracy and precision.
- Pattern height > 100 nm - provide excellent image contrast.
- Uniform coverage of entire chip - save time (can image anywhere).
Description:
- Nominal calibrated dimensions: 300 or 700 nm.
- Calibration certificate: supplied with each sample, stating the dimension to the nearest 1 nm.
- Pattern types: 1- or 2—Dimensional. The calibrated dimension is the same for both axes for the 2-D standard.
- Feature geometry:
-parallel ridges (1-D, 300 or 700 nm)
-cylindrical posts (2-D 300 nm)
-diamond-shaped posts (2-D 700 nm)
- Physical Size: 3 mm x 4 mm x 0.5 mm.
- Substrate: Silicon wafer.
- Top surface: Tungsten film.
The 1-D standards can be scanned using any AFM mode, including contact mode. The 2-D standards can be scanned using modes such as Tapping Mode™, intermittent contact, and non-contact.
