    Abstract: Provided is a method of manufacturing a single crystal Si film. The method includes: preparing a Si substrate on which a first oxide layer is formed and an insulating substrate on which a second oxide layer is formed; forming a dividing layer at a predetermined depth from a surface of the Si substrate by implanting hydrogen ions from above the first oxide layer; bonding the insulating substrate to the Si substrate so that the first oxide layer contacts the second oxide layer; and forming a single crystal Si film having a predetermined thickness on the insulating substrate by cutting the dividing layer by irradiating a laser beam from above the insulating substrate. Therefore, a single crystal Si film having a predetermined thickness can be formed on an insulating substrate.

    Abstract: The invention discloses an etch-back method for planarization at the position-near-interface of an interlayer dielectric (ILD), comprising: depositing or growing a thick layer of SiO2 by the chemical vapor deposition or oxidation method on a surface of a wafer; spin-coating a layer of SOG and then performing a heat treatment to obtain a relatively uniform stack structure; perform an etch-back on the SOG using a plasma etching, and stopping when approaching the position-near-interface of SiO2; performing a plasma etch-back on the remaining SOG/SiO2 structure at the position-near-interface until achieving a desired thickness. Since a two-step etching at the position-near-interface is employed, an extremely good smooth surface of the ILD is obtained. That is, a planar and tidy surface of the ILD is obtained not only in the center region, but also even at the edge of the wafer.
