Title: Innovations of Situan Lam in Magnetic Recording Technology
Introduction
Situan Lam is a notable inventor based in San Jose, CA, who has made significant contributions to the field of magnetic recording technology. With a total of 2 patents, his work focuses on improving the efficiency and quality of electroplating processes used in the manufacturing of magnetic recording heads.
Latest Patents
One of Situan Lam's latest patents is titled "Method to reduce void formation during trapezoidal write pole plating in perpendicular recording." This innovative method involves forming an opening in a mold forming layer and creating a conformal Ru seed layer within that opening. An auxiliary layer made of CoFeNi or its alloys is then formed on the seed layer. The process includes removing part of the auxiliary layer in an electroplating solution by applying a controlled current during an activation step. This method effectively reduces voids in the plated material and improves adhesion, thereby enhancing the overall performance of magnetic recording heads.
Another significant patent by Lam is "Method to reduce ferric ions in ferrous based plating baths." This process allows for the cathodic reduction of unwanted Fe ions to needed Fe ions in an acidic ferrous-based plating bath without the use of reducing agents. By applying a specific auxiliary potential, the method can achieve a molar ratio of [Fe]/[Fe] to 1 ppm, which is beneficial for electroplating soft magnetic films. This innovative approach not only minimizes hazardous waste but also improves the uniformity of plated films.
