    摘要: A method of measuring dimensional characteristics includes providing a substrate and forming a reflective layer over the substrate. A dielectric layer is then formed over the reflective layer. The dielectric layer includes a grating pattern and a resistivity test line inset in a transparent region. Radiation is then directed onto the dielectric layer so that some of the radiation is transmitted through the transparent region to the reflective layer. A radiation pattern is then detected from the radiation reflected and scattered by the metal grating pattern. The radiation pattern is analyzed to determine a first dimensional information. Then the resistance of the resistivity test line is measured, and that resistance is analyzed to determine a second dimensional information. The first and second dimensional informations are then compared.

    摘要: A method includes forming top metal lines over a semiconductor substrate, wherein the semiconductor substrate is a portion of a wafer having a bevel. When the top metal lines are exposed, an etchant is supplied on the bevel, wherein regions of the wafer sprayed with the etchant has an inner defining line forming a first ring having a first diameter. A trimming step is performed to trim an edge portion of the wafer, wherein an edge of a remaining portion of the wafer has a second diameter substantially equal to or smaller than the first diameter.
