HRT 3000 - Non-Contact Optical Profilometer
The HRT 3000 is a non-contact profilometer designed specifically to measure high aspect ratio trenches found in semiconductors and MEMS devices. The many features built into the HRT 3000 make it very flexible and allow it to operate in production as well as research environments. The software is both simple to use and powerful enough to solve numerous metrology problems.
Some of the many applications Tamar has addressed with the HRT 3000 are:
High Aspect Ratio Trenches depth and width for semiconductors
MEMS etch depth and width
Fresnel lens step measurement
Surface profile of optical components and crystals
Solder bumps and micro bumps.
Micro-fluidic chips
Flat Panel Display Photo Spacer Height
Flat Panel Display Layer Thickness
In addition to our standard HRT 3000, we routinely build specific configurations to solve specific applications.

WaferScan – Wafer Bow & Warp Geometry
WaferScan is a big step forward in wafer thickness metrology. WaferScan utilizes Tamar's proprietary Optical Stylus (patent pending) technology to measure the thickness, warp, bow and other shape features of wafers, with high data density and high throughput. WaferScan allows the user to acquire thousands of data points on the surface and can measure thickness of conventional wafers as well as thin wafers and of any material. No optical constants are required and patterned or bumped wafers are easily addressed.
