    摘要： Methods are provided for simultaneously processing transistors in two different regions of an integrated circuit. Planar transistors are provided in a logic region while recessed access devices (RADs) are provided in an array region for a memory device. During gate stack patterning in the periphery, word lines are recessed within the trenches for the array RADs. Side wall spacer formation in the periphery simultaneously provides an insulating cap layer burying the word lines within the trenches of the array.

    摘要： Some embodiments include methods of forming isolation structures. A semiconductor base may be provided to have a crystalline semiconductor material projection between a pair of openings. SOD material (such as, for example, polysilazane) may be flowed within said openings to fill the openings. After the openings are filled with the SOD material, one or more dopant species may be implanted into the projection to amorphize the crystalline semiconductor material within an upper portion of said projection. The SOD material may then be annealed at a temperature of at least about 400° C. to form isolation structures. Some embodiments include semiconductor constructions that include a semiconductor material base having a projection between a pair of openings. The projection may have an upper region over a lower region, with the upper region being at least 75% amorphous, and with the lower region being entirely crystalline.

    摘要： A method of forming a field effect transistor includes forming trench isolation material within a semiconductor substrate and on opposing sides of a semiconductor material channel region along a length of the channel region. The trench isolation material is formed to comprise opposing insulative projections extending toward one another partially under the channel region along the channel length and with semiconductor material being received over the projections. The trench isolation material is etched to expose opposing sides of the semiconductor material along the channel length. The exposed opposing sides of the semiconductor material are etched along the channel length to form a channel fin projecting upwardly relative to the projections. A gate is formed over a top and opposing sides of the fin along the channel length. Other methods and structures are disclosed.

    摘要： Methods of reducing the floating body effect in vertical transistors are disclosed. The floating body effect occurs when an active region in a pillar is cut off from the substrate by a depletion region and the accompanying electrostatic potential created. In a preferred embodiment, a word line is recessed into the substrate to tie the upper active region to the substrate. The resulting memory cells are preferably used in dynamic random access memory (DRAM) devices.

    摘要： Vertical transistors for memory cells, such as 4F2 memory cells, are disclosed. The memory cells use digit line connections formed within the isolation trench to connect the digit line with the lower active area. Vertical transistor pillars can be formed from epitaxial silicon or etched from bulk silicon. Memory cells can be formed by creating a cell capacitor electrically connected to each transistor pillar.
