Abstract: There is provided a three-dimensional integrated circuit manufacturing method for temporarily attaching a chip to a transcription substrate, and securely detaching the chip from the transcription substrate when the chip is transferred to a supporting substrate. When a chip is temporarily attached to a transcription substrate, by evaporating a liquid existing between the chip and the transcription substrate, the solids of the chip and the transcription substrate can be attached to each other. Accordingly, the chip can be temporarily attached to the transcription substrate so as not to be deviated from its own position. Further, by setting adhesive strength between the chip and a supporting substrate to be higher than that between the chip and the transcription substrate, the chip can be securely detached from the transcription substrate when the chip is transferred from the transcription substrate to the supporting substrate.

Abstract: The embodiments of methods described in this disclosure for trimming back nitride spacers for replacement gates allows the hard mask layers (or hard mask) to protect the polysilicon above the high-K dielectric during trim back process. The process sequence also allows determining the trim-back amount based on the process uniformity (or control) of nitride deposition and nitride etchback (or trimming) processes. Nitride spacer trim-back process integration is critical to avoid creating undesirable consequences, such as silicided polyisicon on top of high-K dielectric described above. The integrated process also allows widening the space between the gate structures to allow formation of silicide with good quality and allow contact plugs to have sufficient contact with the silicide regions. The silicide with good quality and good contact between the contact plugs and the silicide regions increase the yield of contact and allows the contact resistance to be in acceptable and workable ranges.

Abstract: The invention includes methods of forming semiconductor constructions and methods of forming pluralities of capacitor devices. An exemplary method of the invention includes forming conductive material within openings in an insulative material to form capacitor electrode structures. A lattice is formed in physical contact with at least some of the electrode structures, a protective cap is formed over the lattice, and subsequently some of the insulative material is removed to expose outer surfaces of the electrode structures. The lattice can alleviate toppling or other loss of structural integrity of the electrode structures, and the protective cap can protect covered portions of the insulative material from the etch. After the outer sidewalls of the electrode structures are exposed, the protective cap is removed. The electrode structures are then incorporated into capacitor constructions.

The first and second spacers are removed to different depths such that side portions of the first and second gate electrodes have different exposed thicknesses. A metal silicide layer is formed on the first and second regions including the first and second gate structures. The metal silicide layer formed on the second gate electrode has a second thickness that is greater than a first thickness of the metal silicide layer formed on the first gate electrode. The spacers in the gate structures of resulting N type and P type MOS transistors are removed to different thicknesses, thereby minimizing deformation in the gate structures and also improving electrical characteristics and thermal stability of the gate electrodes.

The inventive method comprises an n-doping stage during which a donor species is vacuum diffused in a diamond that was initially doped with an acceptor, in order to form donor groups containing the donor species, at a temperature that is less than or equal to the dissociation temperature of the complexes formed between the acceptor and the donor species.

Abstract: A method for treating a copper surface of a semiconductor device provides exposing the copper surface to a citric acid solution after the surface is formed using CMP (chemical mechanical polishing) or other methods. The citric acid treatment may take place during a cleaning operation that takes place in a wafer scrubber, or subsequent to such an operation. The citric acid treatment removes copper oxides that form on copper surfaces exposed to the environment and prevents hillock formation during subsequent high temperature operations. The copper surface is then annealed and the annealing followed by an NH3 plasma treatment which again removes any copper oxides that may be present. The NH3 plasma operation roughens exposed surfaces improving the adhesion of subsequently-formed films such as a dielectric film preferably formed in-situ with the NH3 plasma treatment. The subsequently-formed film is formed over an oxide-free, hillock-free copper surface.
