This paper is a review of our recent work on a micro-manipulation of the shape of a liquid surface by means of modulated magnetic fields[1]. A microscopic field modulation is achieved by insertion of a field modulator in a homogeneous magnetic field. The surface of a feeble magnetic liquid placed on the modulator is modulated according to the modulation of the field produced over the modulator surface (micro-Moses effect). Upon solidification of the liquid by means of photopolymerization, for example, the surface modulation is fixed. In this paper, an application of this technique to the contact-hole formation on the electrode bumps of IC (integrated circuit) chips is presented.
