A method of fabricating an integrated circuit is disclosed. The method of removing excess metal of a metal interconnection layer during integrated circuit fabrication process comprises the steps of: plasma etching an excess metal portion of the metal interconnection layer using plasma comprising a noble gas, for an etch duration. The method further comprises stopping the etch process prior to the excess metal portion being completely removed and thus prior to a dielectric surface upon which the metal interconnection is formed, becoming completely exposed. The remaining excess metal portion comprising excess metal residues is subsequently removed using a second etch step.

The present disclosure is directed to a method of fabrication a semiconductor structure. The method includes providing a substrate and forming a bottom electrode over the substrate, wherein a terminal end of the bottom electrode has a tapered sidewall. The method also includes depositing an insulating layer over the bottom electrode and forming a top electrode over the insulating layer, wherein a terminal end of the top electrode has a vertical sidewall.

Apparatus and methods are disclosed for sample preparation, suitable for online or offline use with multilayer samples. Ion beam technology is leveraged to provide rapid, accurate delayering with etch stops at a succession of target layers. In one aspect, a trench is milled around a region of interest (ROI), and a conductive coating is developed on an inner sidewall. Thereby, reliable conducting paths are formed between intermediate layers within the ROI and a base layer, and stray current paths extending outside the ROI are eliminated, providing better quality etch progress monitoring, during subsequent etching, from body or scattered currents. Ion beam assisted gas etching provides rapid delayering with etch stops at target polysilicon layers. Uniform etching at deep layers can be achieved. Variations and results are disclosed.
