摘要:
A semiconductor chip with uniform topology includes a memory cell having a stacked capacitor self-aligned with a bitline. Thick insulation on the bitline and on interconnect wiring on supports circuits of the chip serves to provide the uniform topology and to provide for the self-alignment of the capacitor and bitline. Bitlines and support circuit interconnect wiring are both formed from the same level of metal but they are patterned in separate masking steps. The stacked capacitors are separated from each other by less than the minimum dimension of the photolithographic system used for fabrication.

A three-dimensional five transistor SRAM trench structure and fabrication method therefor are set forth. The SRAM trench structure includes four field-effect transistors (“FETs”) buried within a single trench. Specifically, two FETs are located at each of two sidewalls of the trench with one FET being disposed above the other FET at each sidewall. Coaxial wiring electrically cross-couples the FETs within the trench such that a pair of cross-coupled inverters comprising the storage flip-flop for the SRAM cell is formed, A fifth, I/O transistor is disposed at the top of the trench structure, and facilitates access to the flip-flop. Specific details of the SRAM trench structure, and fabrication methods therefor are also set forth.
摘要:
An improved semiconductor structure is disclosed, including at least one stud-up and an interconnection line connected thereto, wherein the stud-up and interconnection line are formed from a single layer of metal. The structure is prepared by a method in which an insulator region is first provided on a semiconductor substrate, and is then patterned and etched to define at least one opening having a pre-selected depth. Metal is deposited to fill the opening and form the interconnection line, followed by the patterning and formation of a stud-up of desired dimensions within the metal-filled opening. The lower end of the stud-up becomes connected to the interconnection line, and the upper end of the stud-up terminates at or near the upper surface of the insulator region. Other embodiments also include an interconnected stud-down.An endpoint detection technique can be used to precisely control the height of the stud-up and the width of the interconnection line.
摘要:
The present invention provides a conductive structure for use in semiconductor devices. The structure can be used to interconnect the various diffusion regions or electrodes of devices formed on a processed semiconductor substrate to a layer of metal, to interconnect overlying layers of metal or to provide the gate electrode of an FET device formed on the surface of a semiconductor substrate. Various embodiments of the invention are described, but in broad form the active metallurgy of the present invention comprises a thin continuous layer to titanium--titanium nitride and a thick layer of a refractory metal, e.g. tungsten, overlying the titanium nitride layer.
摘要:
A method is provided for filling undesired sublithographic contact hole defects in a semiconductor structure caused by misalignment and undesirable overlap of metal line images over contact openings during photolithographic patterning. Unwanted contact between conductive metallization levels through these defects is thereby diminished. The method also provides self-alignment of the lines and contact holes for subsequent formation of stud via connections through which contact is desired to underlying metallization levels. Deposition of a conformal sacrificial material film fills the small, undesired sublithographic contact hole image formed and covers both mask surfaces through which the misaligned line image and contact opening were etched. Isotropic etching removes the conformal layer from all planar surfaces except those of the undesired sublithographic contact hole image. Translation into the underlying insulating layer results in the formation of only contact holes through which contact with underlying substrate metallization is desired. The method of the present invention may alternatively be practiced after the undesired sublithographic contact hole image is etched into the insulating layer to the underlying substrate metallization. Translation of sublithographic defects in a single mask layer overlying an insulating layer disposed over a substrate having metallization therein can also be avoided.
摘要:
Methods for alignment of stacked integrated circuit chips and the resultant three-dimensional semiconductor structures. A thickness control layer is deposited, as needed, on each integrated circuit chip. The thickness of the layer is determined by the thickness of the chip following a grind stage in the fabrication process. Complementary patterns are etched into the thickness control layer of each chip and into adjacent chips. Upon stacking the chips in a three dimensional structure, precise alignment is obtained for interconnect pads which are disposed on the edges of each integrated circuit chip. Dense bus and I/O networks can be thereby supported on a face of the resultant three-dimensional structure.
