FP Series

Contact Profiler Exceptional sensitivity

Contact Profiler

Toho custom profilers offer comprehensive measurement capabilities for mass production and research facilities that demand accuracy, performance and value.

Incorporating KLA-Tencor’s proprietary low-force measurement head, Toho Profilers provide low stylus force and achieve highly accurate micron to nanometer range measurements to analyze surface flatness, surface roughness, waviness, peak to valley, curvature, texture, stress, and feature dimensions on any square FPD substrate larger than 300mm.

Industry Leading Repeatability

Toho Profilers provide industry leading measurement repeatability and features configured to your specific application and price range. Enhancing tool value and Material Characterization performance Toho also provides various options to the standard platform.

Substrate Accommodation

Toho Profilers fit all applications with smaller substrate systems featuring an X, Y, axis moving stage and larger systems utilizing gantry positioned heads

KLA-Tencor Micro Head

With outstanding patented measurement technology, best in class profilometry is achieved with exceptional stylus sensitivity

Stylus Profiling

The standard L-Stylus (2µm, 60°) allows for precision scanning with force ranges from 0.5mg to 15mg providing up to 90mm continuous scan length at 25mm per second. Stage area

Theory: Scanning Mechanism

To precisely scan features on various substrates on the A-type models, the Toho FP series utilize a specialized scanning system which primarily consists of an X-drive assembly and an optical flat. The X-drive is equipped with two motors, (slow / fast) that allow for more efficient scanning. The optical flat allows for the stylus to trace a pattern on a wide variety of samples in a straight line.

Theory: Measurement

The Patented Micro Head uses an “L-Stylus” that achieves a pattern trace with precise appropriate force. Depending on the material of the pattern being measured, this force is carefully controlled to prevent damage to the sample and the stylus. The sensor in the head detects the subtle movement of the stylus and the data captured in the Micro Head is then sent to the computer for manipulation.
