No compromise. Plating rate and uniformity performance results.
Leading manufacturers of GaAs and GaN devices are choosing Solstice GoldPro as their plating technology for applications from RF to VCSELs and microLEDs.
Our Solstice® GoldPro™ electrochemical deposition plating chambers are designed to deliver efficiency, speed, and improved cost of ownership to your process. The chamber leverages our proprietary fluid flow and electric field shaping technology to give you high plating rates and uniform depositions every time.
In addition, plating chambers can be supplied with chemistry via individual tanks or shared tanks. Nitrogen protection is offered in the bath and in the plating chamber to maximize sulfite bath life. Our GoldPro technology is further differentiated by its ability to plate highly uniform features without the added maintenance complexity of submerged agitators.
