    Abstract: In a semiconductor memory device and a method of manufacturing the same, an insulating layer is formed on a substrate having a logic region on which a first pad is provided and a cell region on which a second pad and a lower electrode are subsequently provided. The insulating layer is etched to be a first insulating layer pattern having a first opening exposing the first pad. A first plug is formed in the first opening. The first insulating layer pattern where the first plug is formed is etched to be a second insulating layer pattern having a second opening exposing the lower electrode. A second plug including a phase-changeable material is formed in the second opening. A conductive wire and an upper electrode are formed on the first plug and the second plug, respectively.

    Abstract: An example embodiment relates to a method of forming a pattern structure, including forming an object layer on a substrate, and forming a hard mask on the object layer. A plasma reactive etching process is performed on the object layer using an etching gas including a fluorine containing gas and ammonia (NH3) gas together with oxygen gas to form a pattern. The oxygen gas is used for suppressing the removal of the hard mask during the etching process.

A mask pattern is formed on a region of the second magnetic layer. A magnetic tunnel junction layer pattern and a sidewall dielectric layer pattern on at least one sidewall of the magnetic tunnel junction layer pattern are formed by performing at least one etch process and at least one oxidation process multiple times. The at least one etch process may include a first etch process to etch a portion of the magnetic tunnel junction layer using an inert gas and the mask pattern to form a first etch product. The at least one oxidation process may include a first oxidation process to oxidize the first etch product attached on an etched side of the magnetic tunnel junction layer.
