Abstract: PURPOSE: To avoid occurrence of exfoliation of the anti-corrosion film under being etched and the microcracks of the glass surface under the pellet formation by forming the anti-corrosion film after coarsening the surface of the glass coated on semiconductor wafer.  
     CONSTITUTION: Glass film 12 is formed into mesa groove 10 on semiconductor wafer (a), and then film 12 is treated with the mixture solution of fluoric acid and ammonium fluoride to secure the coarsened surface. Anti-corrosion film 16 is coated over the entire surface of wafer (a). Thus the complicated intermeshing is obtained between the fine uneveness of the surface of film 12 and film 16 to secure the solid adhesion. As a result, no exfoliation is caused for film 16 in the subsequent selective etching process. Also in case the pellets are produced by giving cut-off and isolation to glass part 12, the occurrence of the lateral microcracks can be prevented because of the coarsened glass surface, thus reducing the defective external appearance or impairment of the characteristics caused by the pellet formation.
