    Patent number: 6340641
    Abstract: The present invention provides a method of easily planarizing the uneven surface of a substrate having an uneven surface. This method comprises the steps of forming a coating film containing spherical fine particles on a surface of a smooth substrate; sticking the surface of the smooth substrate provided with the coating film containing spherical fine particles to the uneven surface of a substrate having an uneven surface; and transferring the coating film containing spherical fine particles to the uneven surface of the substrate so that the uneven surface is planarized.
