Referring to FIGS. 22 and 22A, insulative material 46 is formed within the trenches 112, and conductive gate material 50 is formed over the insulative material. The insulative material 46 may be referred to as second insulative material to distinguish it from the first insulative material 72. The insulative material 46 and conductive material 50 may be considered to be formed adjacent sides of the first and second posts 88 and 90; with the conductive material 50 being spaced from such sides by the insulative material 46. In some embodiments, the conductive material 50 may be considered to be configured as a line extending along the cross-section of FIG. 22, and extending across the first and second posts 88 and 90.

Referring to FIGS. 23 and 23A, upper surfaces of the insulative material 46 and conductive material 50 are recessed, and the insulative material 44 is formed over the recessed upper surfaces. The recessing of the conductive material 50 patterns such material into gates 48. One of the gates 48 is diagrammatically illustrated in FIG. 23. However, such gate is out of the plane relative to the cross-section of FIG. 23, and accordingly is shown in dashed-line view.
