Thickness measurement of various materials, capable of handling both during and after processing across a wide measurement range with a single device! Also suitable for wafer inspection applications.
The PreciTech 2IT series is a non-contact thickness measurement sensor that utilizes spectral interference methods. It excels in high-speed and high-precision thickness measurements and is used for measuring and inspecting the thickness of wafers, films, coatings, and air gaps. It is also capable of measuring impurity/doped wafers. Other features include a wide measurement range, large allowable angles, and compatibility with various materials. There is also an area scanner that allows for surface measurements without scanning via a moving stage. There are numerous instances of its incorporation into semiconductor manufacturing equipment, and it is also used in LCD manufacturing equipment, film thickness monitoring, in-situ, and inline inspections. Additionally, it is utilized as a sensor for desktop machines such as standalone units. **Applications**: Thickness measurement before and after wafer processing (such as polishing), thickness measurement during processing, film/coating thickness measurement, glass wafer thickness inspection, TTV, thickness distribution, PCB coating thickness, battery foil thickness, glass thickness, air gaps, and more.

basic information
【Product Lineup】 - Single Point Sensors (2IT, 2IT-DW, 2IT-RW) These are sensors for thickness measurement, allowing selection of appropriate lighting based on surface condition and material. The 2IT-DW series is optimal for measuring doped wafers, while the 2IT-RW series is best for rough-surfaced wafers. They can perform high-speed measurements of up to 70kHz and cover a range from thin films (a few micrometers) to thick films (1260 micrometers) with multiple probes. - Area Scanner Sensors (Flying Spot Scanner) This type allows area scanning with a 2-axis galvanometer. It is unaffected by vibrations and does not require an operating stage. Available in φ40, φ80, and φ300mm types, it can perform high-speed measurements of up to 70kHz. 【Other Features】 - Measurement Range: 2IT1000 60μm–8000μm (n=1) 2IT500 35μm–4000μm (n=1) - Resolution: Up to 1nm (n=1) - Interface: Ethernet, RS422, Analog (2ch) *For more details, please refer to the PDF document or feel free to contact us.
