Abstract:
In a method of forming a trench structure having a wide void therein, a first trench having a first width and a first depth is formed in a substrate. The first trench is filled with a first insulation layer pattern defining the void in the first trench. A second trench is formed on the first trench. The second trench has a second width wider than the first width and a second depth shallower than the first depth. The second trench is filled with a second insulation layer pattern. After an insulating interlayer on the substrate including the first and second trenches, a conductive line is formed on a portion of the insulating interlayer where the second trench is positioned so that an inductor is formed over the trench structure.

The spacer layer is etched to form a spacer on a sidewall of the split gate structure and a second gate insulation layer pattern on the ultra high voltage region of the substrate. A gate electrode is formed on each of the high voltage region of the substrate, the second gate insulation layer pattern, and the low voltage region of the substrate.

The primary coil assembly includes a plurality of primary coils formed in a plurality of metal layers, and a first interlayer connection unit for connecting the primary coils. The secondary coil assembly includes a plurality of secondary coils formed in the plurality of metal layers, and a second interlayer connection unit for connecting the secondary coils. The primary and secondary coils formed in the same metal layer are concentric and axisymmetric with respect to a diameter line passing through a planar center point. A balanced-unbalanced transformer (balun) is a type of transformer that may be used to convert an unbalanced signal to a balanced one or vice versa. An integrated circuit may include a semiconductor substrate and a transformer. Electrical elements such as transistors may be formed on the semiconductor substrate.
Abstract:
In a capacitor structure and method of forming the same, a first electrode, a second electrode, and a first insulation layer are sequentially formed on a substrate. The first and second electrodes and the first insulation layer are covered with a second insulation layer on the substrate. A first plug is in contact with the second electrode through the second insulation layer. A second plug is in contact with the first electrode through the first and second insulation layer. A third insulation layer is formed on the second insulation layer. Third and fourth comb-shaped electrodes are formed in the third insulation layer. The third electrode is contact with the first plug and the fourth electrode is contact with the second plug while facing the third electrode. Thus, the teeth of the comb-shaped electrodes are alternately arranged and spaced apart in the third insulation layer.
