  • Patent number: 9385045
    Abstract: Some embodiments include methods of forming gated devices. An upper region of a semiconductor material is patterned into a plurality of walls that extend primarily along a first direction. The walls are spaced from one another by trenches that extend primarily along the first direction. Steps are formed along bottoms of the trenches. Gatelines are formed on the steps and along lower regions of the walls. After the gatelines are formed, the walls are patterned into spaced-apart pillars that have bottom regions below the gatelines. In some embodiments the gated devices may be transistors or thyristors.

  • Patent number: 9356095
    Abstract: Vertical devices and methods of forming the same are provided. One example method of forming a vertical device can include forming a trench in a semiconductor structure, and partially filling the trench with an insulator material. A dielectric material is formed over the insulator material. The dielectric material is modified into a modified dielectric material having an etch rate greater than an etch rate of the insulator material. The modified dielectric material is removed from the trench via a wet etch.

  • Patent number: 9224738
    Abstract: A method of forming an array of gated devices includes forming trenches between walls that longitudinally extend in rows and project elevationally from a substrate. The walls comprise semiconductor material. Gate dielectric is formed within the trenches laterally over side surfaces of the walls and conductive gate material is formed within the trenches laterally over side surfaces of the gate dielectric. Side surfaces of an elevationally inner portion of the gate material within the trenches are laterally covered with masking material and side surfaces of an elevationally inner portion of the gate material within the trenches are laterally uncovered by the masking material. The elevationally outer portion of the gate material that is laterally uncovered by the masking material is removed while the side surfaces of the elevationally inner portion of the gate material are laterally covered by the masking material to form gate lines within the trenches laterally over elevationally inner portions of the walls.

  • Patent number: 9209187
    Abstract: A method of forming an array of gated devices includes forming a plurality of semiconductor material-comprising blocks individually projecting elevationally from a substrate and spaced from one another along rows and columns. A gate line is formed laterally proximate each of two opposing sidewalls of the blocks along individual rows of the blocks. After forming the gate lines, semiconductor material of the blocks is removed laterally between the gate lines to form pairs of pillars from the individual blocks that individually have one of the gate lines laterally proximate one of two laterally outermost sidewalls of the pair and another of the gate lines laterally proximate the other of the two laterally outermost sidewalls of the pair. Other methods are disclosed.

  • Publication number: 20150235713
    Abstract: A method of forming a memory device having magnetic tracks individually comprising a plurality of magnetic domains having domain walls, includes forming an elevationally outer substrate material of uniform chemical composition. The uniform composition material is partially etched into to form alternating regions of elevational depressions and elevational protrusions in the uniform composition material. A plurality of magnetic tracks is formed over and which angle relative to the alternating regions. Interfaces of immediately adjacent of the regions individually form a domain wall pinning site in individual of the magnetic tracks. Other methods, including memory devices independent of method, are disclosed.

  • Patent number: 9111773
    Abstract: A three dimensional shallow trench isolation structure including sets of parallel trenches extending in two perpendicular directions may be formed by depositing a conformal deposition in a first set of parallel trenches, oxidizing the second set of trenches to enable selective deposition in said second set of trenches and then conformally depositing in said second set of trenches. In some embodiments, only one wet anneal, one etch back, and one high density plasma chemical vapor deposition step may be used to fill both sets of trenches.
