CONTACT ANGLE METER / OPTICAL TENSIOMETER

Universal CAM

Basic version with 1 manual dosing unit
​
A dependable measuring instrument is available for contact angle, Surface Free Energy (SFE), and surface tension assessments, offering a range of customisable options. These options include motorised dispensers, multi-dispensers, and a tilting stage, enhancing the instrument's versatility and functionality.

The modification of wetting properties through specialised surface treatments is increasingly prevalent in both industrial and research settings. To effectively characterise processes, fine-tune technological parameters, and ensure precise production control, it is imperative to conduct objective and accurate measurements of surface free energy before and after the modification process.

Wafer Processing CAM

The surface tension of photolithographic materials, such as resist and developer, plays a pivotal role in optimising the photolithographic process. Critical factors such as the uniformity of spin coatings, planarisation, and adhesion are intricately linked to the surface tension of these materials.

In semiconductor technology, the Wafer Processing contact angle meter serves as an invaluable tool for measuring contact angle and Surface Free Energy (SFE). Notably, it encompasses the full spectrum of functionalities essential for 300mm wafer fabs, rendering it a truly unique and unparalleled device on a global scale.
