MAMUFACTURING METHOD FOR THIN MAGNETIC HEAD AND THIN MAGNETIC HEAD

摘要

PURPOSE: A thin film magnetic head is provided to replace many portions of an oxide insulation layer formed by a sputtering process with a resist, so as to regularly apply the oxide insulation layer around a pad and reduce a process time. CONSTITUTION: A function layer(12) is deposited on a substrate(11). A plating bottom layer(13), a metal pad(14), and a gold bump(17) are sequentially formed on a front one end of the function layer(12). A resist(15') is formed lower than an upper end of the metal pad(14) in other parts except the front one end of the function layer(12). An oxide insulation layer(16) is formed on top of the resist(15').
