Title: Grooving method
Inventor: OTSUKA YASUHIRO
IPC: C23F1/00
Filed: 1986-01-24
Abstract: PURPOSE:To form grooves having no burrs to metallic films of the lower layers with high accuracy by forming the different multi-layered metallic films on a substrate and forming grooves on the metallic films by using a tool then etching away only the metallic films of the upper layer. CONSTITUTION:Cr is extremely thinly sputtered and coated on the hard substrate 11 which is a polished glass disk and thereafter, an Au film 12 and an Ni film 13 are successively formed thereon by sputtering and coating. The above-mentioned substrate 11 is fixed into an air spindle 14 having a shaft 20 and while the substrate is rotated, a diamond tool 15 having an inverted trapezoidal cutting edge 18 is pressed onto the substrate under prescribed vertical load F to form the groove 16' having a slight burr 17 to the Au film 12 and the Ni film 13. The films are then etched by using an FeCl3 soln. to remove the Ni film 13 together with the burr 17. The groove 16 of the prescribed shape having no burrs is thereby formed on the Au film 12 on the substrate 11.
