    Abstract: A method includes etching a gate stack to form a trench extending through the gate stack, the gate stack including a metal gate electrode and a gate dielectric, wherein forming the trench removes a portion of the gate stack to separate the gate stack into a first gate stack portion and a second gate stack portion; extending the trench through an isolation region under the gate stack and into a semiconductor substrate under the isolation region; conformally depositing a first dielectric material on surfaces in the trench; and depositing a second dielectric material on the first dielectric material to fill the trench, wherein the first dielectric material is a more flexible material than the second dielectric material.

    Abstract: A method for improving reliability of interconnect structures for semiconductor devices is disclosed. The method includes forming a contact structure on a transistor and forming a metallization layer on the contact structure. The forming the metallization layer includes depositing an inter-metal dielectric (IMD) layer on the transistor, forming an opening within the IMD layer to expose a top surface of the contact structure, depositing a metallic layer to fill the opening, forming an electron barrier layer within the IMD layer, and forming a capping layer within the metallic layer. The electron barrier layer has a hole carrier concentration higher than a hole carrier concentration of a portion of the IMD layer underlying the electron barrier layer. The capping layer has a hole carrier concentration higher than a hole carrier concentration of a portion of the metallic layer underlying the capping layer.

    Abstract: The present disclosure relates to a method of inspecting a photomask to decrease false defects, which uses a plurality of image rendering models with varying emphasis on different design aspects, and an associated apparatus. In some embodiments, the method is performed by forming an integrated circuit (IC) design comprising a graphical representation of an integrated circuit. A first image rendering simulation is performed on the IC design using an initial image rendering model to determine a plurality of initial mask defects. A second image rendering simulation is performed on the IC design using a modified image rendering model that emphasizes a design aspect to determine a plurality of modified mask defects. By comparing the plurality of initial mask defects with the plurality of modified mask defects, falsely identified mask defects can be detected and eliminated.
