Latest Patents

Stefan's latest patents include a "Conductive stud for magnetic recording devices and method of making the same." This invention involves a magnetic recording device that utilizes an 'anchored' conductive stud, securely attached within its surrounding insulator materials. The conductive stud is formed over a conductive layer that is part of a read or write head element of the magnetic recording device. The design features a top stud portion and a bottom undercut portion, with the latter having a width greater than that of the top stud portion. This configuration ensures a secure coupling between the conductive stud and the conductive layer, which is preferably made of copper (Cu), while the conductive stud itself is made of gold (Au) and the insulator is alumina (AlO). Additionally, a method of making the conductive stud using a photolithography process is disclosed.
