Resumen
Ni electroless films were used as a material for hard mask during highdensity ICP plasma etching. The results have shown that under the plasma exposure strong hardening of the mask occurs and the rate of Ni film removal falls at least an order of magnitude as compared with its initial value. Therefore, very high selectivities for Si etching over Ni are obtained, allowing for very deep etching required for some MEMS applications. © The Electrochemical Society. 14 1 403 411 Yu, H.S., Luo, S.F., Wang, Y.-R., A comparative study on the crystallization behavior of electroless Ni-P and Ni-Cu-P deposits (2001) Surface and Coatings Technology, 148, pp. 143-148 Park, Y.S., Kim, T.H., Lee, M.H., Kwon, S.C., Study on the effect of ultrasonic waves on the characteristics of electroless nickel deposits from an acid bath (2002) Surface and Coatings Technology, 153, pp. 245-251 Bates, J., Why Use Electroless Nickel Today?
