Photoresist Coating Systems for MEMs and Semiconductor

Siansonic ultrasonic spray coating technology can provide a solution to create the highly uniform photoresist coatings on wafers, MEMs, glass etc.. Compared with conventional spin coating and dip coating, ultrasonic coating can offer better film on micro-structures and no limit on substrate size.

Siansonic's spray coating systems can deal with both flat and 2.5D/3D substrates including silicone wafers, glass, metal, ceramic, plastic, etc. 


  • Uniform coatings on both flat and 3D micro-structures.

  • No limitation on substrate size.

  • Low cost on maintenance.

  • High transfer efficiency of raw material.

  • Highly repeatable and controllable deposition process.
