    摘要: A method of testing a wafer after a current top layer is formed over the wafer. Stress data is collected for the wafer after forming the current top layer. The stress data is derived from changes in wafer curvature. The stress data includes: stress-xx in an x direction and stress-yy in a y direction for each area of a set of finite areas on the wafer, the stress-xx and stress-yy both being derived from wafer-curvature-change-xx in the x direction for each area of the set of finite areas and from wafer-curvature-change-yy in the y direction for each area of the set of finite areas; and the stress-xy being derived from wafer-curvature-change-xy, wherein wafer-curvature-change-xy is a change in wafer twist in the x-y plane for each area of the set of finite areas. A stress gradient vector (and/or its norm) is calculated and used to evaluate the investigating single or multiple accumulated layer.

    摘要: A method for reducing leakage current in a semiconductor structure is disclosed. One or more dielectric layers are formed on a semiconductor substrate, on which at least one device is constructed. A hydrogen-containing layer is formed over the dielectric layers. A silicon nitride passivation layer covers the dielectric layers and the hydrogen-containing layer. The hydrogen atoms of the hydrogen-containing layer are introduced into the dielectric layers without being blocked by the silicon nitride layer, thereby reducing leakage current therein.

    摘要: A novel method for forming electrodes in the fabrication of an MIM (metal-insulator-metal) capacitor, is disclosed. The method improves MIM capacitor performance by preventing plasma-induced damage to a dielectric layer during deposition of a top electrode on the dielectric layer, as well as by reducing or preventing the formation of an interfacial layer between the dielectric layer and the electrode or electrodes, in fabrication of the MIM capacitor. The method typically includes the patterning of crown-type capacitor openings in a substrate; depositing a bottom electrode in each of the crown openings; subjecting the bottom electrode to a rapid thermal processing (RTP) or furnace anneal step; depositing a dielectric layer on the annealed bottom electrode; depositing a top electrode on the dielectric layer using a plasma-free CVD (chemical vapor deposition) or ALD (atomic layer deposition) process; and patterning the top electrode of each MIM capacitor.
