Abstract
Methods, systems, and devices related to a memory device with a thermal barrier are described. The thermal barrier (e.g., a low density thermal barrier) may be positioned between an access line (e.g., a digit line or a word line) and a cell component. The thermal barrier may be formed on the surface of a barrier material by applying a plasma treatment to the barrier material. The thermal barrier may have a lower density than the barrier material and may be configured to thermally insulate the cell component from thermal energy generated in the memory device, among other benefits.
Claims18
A method, comprising:
- forming a barrier material associated with a cell material configured to store data, the barrier material having a first density;
- applying plasma to the barrier material to form a portion of the barrier material having a second density that is less than the first density;
- and
- forming an access line so that the barrier material is positioned between the cell material and the access line.
A product formed by a process, comprising:
- forming a barrier material associated with a cell material configured to store data, the barrier material having a first density;
- applying plasma to the barrier material to form a portion of the barrier material having a second density that is less than the first density;
- and
- forming an access line so that the barrier material is positioned between the cell material and the access line.
A memory device, comprising:
- an access line of a plurality of access lines of the memory device configured to access a memory array of cell components;
- and
- a barrier material positioned between a cell component and the access line, the barrier material having a first density, wherein a modified portion of the barrier material has a second density that is less than the first density based at least in part on the modified portion of the barrier material resulting from applying a plasma to the barrier material.
