Copper Film Measurement System
As film thickness and distribution control of metal thin film deposited on wafer play important roles in the characteristics of the device and yields in the semiconductor wiring process, it is an important element of quality control. While the commonly used conventional measuring methods were contact systems and only indirect evaluation by monitor wafer could be carried out, MESEC is equipped with an automatic transfer system compatible with up to 300mm wafer and it can measure directly on wafers from practical production and, therefore, more reliable data can be obtained. Furthermore, it will contribute to a reduction in the quantity of monitor wafers. Stand-alone type MESEC-SAT and built-in type MESEC-BIT are available.
Features
- Non-contact and non-destructive measurement of the thickness of metal thin film on silicon wafer can be carried out and the process can be evaluated directly with product wafers.
- As the eddy current sensor is smallsized and the measurement speed is high, it is possible to mount to and measure on tools for PVD, CVD, ECD, CMP, etc.
- An automatic calibration method has been developed, the influences of drift of the measurement system can be removed, and the repeatability of thickness measurement is excellent.
