Siansonic provides photoresist coating solutions for semiconductor wafer by using advanced ultrasonic spray coating technology, which has the advantages of high uniformity, better microstructure wrapping and coating for any area compared with conventional technologies such as spin coating and dip coating. The ultrasonic spray coating system of Siansonic can control the spraying flow, coating speed and loading amount excellently.

The precision cleaning method for semiconductor wafer is megasonic cleaning, a technology that has been controlled by developed countries such as the United States and Japan. After years of research and development, Siansonic has successfully developed megasonic cleaning technology with a maximum of 3000 kHz.

The advanced ultrasonic spray coating technology of Siansonic is used in the solder fluxing coatings for circuit board, which has the edges of higher uniformity, precision, reducing raw material waste compared with conventional two-fluid spray coating method, thus VOCs emissions can be reduced and the system maintenance cost is lower
