Sreekrishnan Sankaranarayan is an accomplished inventor based in Santa Clara, CA. He has made significant contributions to the field of plasma sputtering technology. His innovative approach has led to the development of a unique mechanism that enhances the efficiency of sputter magnetrons.

Latest Patents

Sreekrishnan holds a patent for a "Mechanism for varying the spacing between sputter magnetron and target." This invention features a lift mechanism that allows a magnetron to be controllably lifted away from the target to compensate for sputter erosion. This adjustment is crucial for maintaining a constant magnetic field and plasma density at the sputtered surface. The design is particularly beneficial for stable operation with smaller magnetrons, which may execute circular or planetary motion about the target axis. The lift mechanism can be operated using a lead screw and lead nut system or a vertically moving slider, with the lift amount controlled based on power applied to the target or by monitoring electrical characteristics.
