Title: Manufacture of surface acoustic wave element
Inventor: KONDO TAKEO
IPC: H03H3/08
Filed: 1994-06-02
Abstract: PURPOSE:To prevent an electrode of a surface acoustic wave element from being damaged even when a chip by chipping comes to a forming face of a wafer by providing an alkali-soluble resin or the like to the wafer forming face as a protection film and removing the protection film after the wafer is split when the electrode of the surface acoustic wave element is provided to the electrode forming face of the wafer. CONSTITUTION:The thickness of a wafer 1 made of a LiTaO3 or LiNbO3 or the like is selected to be 400-500mum, and when an electrode 2 made of Al is formed on the wafer, at first an alkali-soluble resin is applied in advance on the surface of the wafer 1 by using a spin coater or the like to obtain a film thickness of nearly 2mum and the coated film covers the electrode 2 formed on the surface of the wafer 1 as a protection film 5. Then the film 5 is subjected to baking and the wafers 1 including the electrode are split in this state. Then the protection film 5 is removed by immersing the wafer 1 in an alkali solution. Furthermore, a self-adhesive sheet is adhered so as not to prevent chips from being scattered after splitting to a major face 1a on which no electrode 2 is formed.
