특정한 화학식으로 표시되는 지환족 불포화 화합물 또는 특정한 화학식으로 표시되는 방향족 화합물 1몰 내지 3몰; 및 특정 화학식으로 표시되는 사이클로펜타디에닐 지르코늄(IV)계 화합물 1몰 내지 3몰의 비율로 혼합된 것을 특징으로 하는 지르코늄 함유막 형성용 전구체 조성물 및 이를 이용한 지르코늄 함유막 형성 방법이 개시된다. 상기 조성물에서 상기 2종의 구성 화합물은 서로 반응하지 않고 액체 상태에서 서로 안정하고 균일하게 혼합된 상태로 존재하기 때문에, 상기 조성물은 마치 하나의 화합물처럼 거동하며 높은 증기압을 나타낸다. 상기 본 발명의 조성물을 사용하면 간편하게 경제적으로 고품질의 지르코니아와 같은 지르코늄 함유막을 얻을 수 있다.
Abstract:
Described are methods for atomic layer deposition of films comprising mixed metal oxides using metal amidinate precursors. The mixed metal oxide films may comprise a lanthanide and a transition metal such as hafnium, zirconium or titanium. Such mixed metal oxide films may be used as dielectric layers in capacitors, transistors, dynamic random access memory cells, resistive random access memory cells, flash memory cells and display panels.
Abstract:
Techniques are disclosed for forming through-silicon vias (TSVs) implementing a negative thermal expansion (NTE) material such as zirconium tungstate (ZrW2O8) or hafnium tungstate (HfW2O8). In some cases, the NTE material is disposed between the substrate and conductive core material of the TSV and serves to offset, at least in part, the coefficient of thermal expansion (CTE) mismatch there between, thus reducing heat-induced stresses and/or protrusion (pumping) of the conductive core material. The NTE material also may protect against leakage, voltage breakdown, and/or diffusion of the conductive core material. Furthermore, the NTE material may reduce radial stresses in high-aspect-ratio TSVs. In some cases, techniques disclosed herein may improve TSV reliability, enhance three-dimensional integration, and/or enhance performance in three-dimensional integrated circuits and/or other three-dimensional packages. Other embodiments which can employ techniques described herein will be apparent in light of this disclosure.
Abstract:
A method for doping a dielectric material by pulsing a first dopant precursor, purging the non-adsorbed precursor, pulsing a second precursor, purging the non-adsorbed precursor, and pulsing a oxidant to form an intermixed layer of two (or more) metal oxide dielectric dopant materials. The method may also be used to form a blocking layer between a bulk dielectric layer and a second electrode layer. The method improves the control of the composition and the control of the uniformity of the dopants throughout the thickness of the doped dielectric material.
Abstract:
Provided methods of etching and/or patterning films. Certain methods comprise exposing at least part of a film on a substrate, the film comprising one or more of HfO 2 , HfB x O y , ZrO 2 , ZrB x O y , to a plasma comprising BCl 3 and argon to etch away said at least part of the film. Certain other methods relate to patterning substrates using said methods of etching films.

Abstract:
Provided are low temperature methods of depositing hafnium or zirconium containing films using a Hf(BH 4 ) 4 precursor, or Zr(BH 4 ) 4 precursor, respectively, as well as a co-reactant. The co-reactant can be selected to obtain certain film compositions. Co-reactants comprising an oxidant can be used to deposit oxygen into the film. Accordingly, also provided are films comprising a metal, boron and oxygen, wherein the metal comprises hafnium where a Hf(BH 4 ) 4 precursor is used, or zirconium, where a Zr(BH 4 ) 4 precursor is used.
