Abstract: Embodiments of the present disclosure generally include spin-orbit torque magnetoresistive random-access memory (SOT-MRAM) devices and methods of manufacture thereof. The SOT-MRAM devices described herein include an SOT layer laterally aligned with a magnetic tunnel junction (MTJ) stack and formed over a trench in an interconnect. Thus, the presence of the SOT layer outside the area of the MTJ stack is eliminated, and electric current passes from the interconnect to the SOT layer by SOT-interconnect overlap. The devices and methods described herein reduce the formation of shunting current and enable the MTJ to self-align with the SOT layer in a single etching process.

Abstract: Methods for plasma enhanced chemical vapor deposition (PECVD) of silicon carbonitride films are described. A flowable silicon carbonitride film is formed on a substrate surface by exposing the substrate surface to a precursor and a reactant, the precursor having a structure of general formula (I) or general formula (II) wherein R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, and R12 are independently selected from hydrogen (H), substituted or unsubstituted alkyl, substituted or unsubstituted alkoxy, substituted or unsubstituted vinyl, silane, substituted or unsubstituted amine, or halide; purging the processing chamber of the silicon precursor, and then exposing the substrate to an ammonia plasma.

Abstract: Embodiments of the present disclosure generally relate to a method for forming an opening using a mask. In one embodiment, a method includes forming a mask on a feature layer. The method includes forming a first opening in the mask to expose a portion of the feature layer. The method further includes forming a carbon layer on the mask and the exposed portion of the feature layer. The method also includes removing portions of the carbon layer and a portion of the exposed portion of the feature layer in order to form a second opening in the feature layer.

Abstract: Methods and apparatus for processing a substrate and etching a nickel silicide layer are provided herein. In some embodiments, a method of etching a nickel silicide film in a semiconductor device include: contacting a nickel silicide film disposed on a substrate in a process chamber with an etching gas sufficient to form one or more soluble or volatile products in order to reduce or eliminate re-deposition of products formed from the nickel silicide film upon the nickel silicide film.
