    摘要: Methods, systems, and devices for memory arrays that use a conductive hard mask during formation and, in some cases, operation are described. A hard mask may be used to define features or components during the numerous material formation and removal steps used to create memory cells within a memory array. The hard mask may be an electrically conductive material, some or all of which may be retained during formation. A conductive line may be connected to each memory cell, and because the hard mask used in forming the cell may be conductive, the cell may be operable even if portions of the hard mask remain after formation.

    摘要: The present disclosure discloses a chemical mechanical polishing apparatus including a polishing machine platform, an electrode film, a polishing pad and a wafer carrier. The electrode film has a first single electrode structure and is disposed on the polishing machine platform. The polishing pad is disposed on the electrode film. The wafer carrier is disposed on the polishing machine platform. In particular, the first single electrode structure generates a first homopolar electric field on the polishing pad.

    摘要: A method of etching patterned heterogeneous silicon-containing structures is described and includes a remote plasma etch with inverted selectivity compared to existing remote plasma etches. The methods may be used to conformally trim polysilicon while removing little or no silicon oxide. More generally, silicon-containing films containing less oxygen are removed more rapidly than silicon-containing films which contain more oxygen. Other exemplary applications include trimming silicon carbon nitride films while essentially retaining silicon oxycarbide. Applications such as these are enabled by the methods presented herein and enable new process flows. These process flows are expected to become desirable for a variety of finer linewidth structures. Methods contained herein may also be used to etch silicon-containing films faster than nitrogen-and-silicon containing films having a greater concentration of nitrogen.

    摘要: A polishing slurry composition is provided. The polishing slurry composition includes at least two types of abrasive particles among first abrasive particles, second abrasive particles, and third abrasive particles, and an oxidizer. A peak-to-valley roughness Rpv decreases when a contact area between the abrasive particles and a tungsten-containing film increases.
