摘要:
Apparatus and method for determination of the endpoint of a cleaning process in which cleaning fluid is contacted with a structure to effect cleaning thereof. The cleaning process includes contacting a cleaning fluid with a structure to be cleaned and producing a cleaning effluent having a sensible heat thermal energy characteristic corresponding to extent of cleaning of the structure, disposing an object in the cleaning effluent that interacts with the cleaning effluent to produce a response indicative of the sensible heat thermal energy characteristic of the cleaning effluent, and monitoring such response to determine when the cleaning is completed. An endpointing algorithm and endpoint monitoring are also described, as well as endpoint monitor sensor elements that are useful to determine endpoint conditions in an efficient and reproduceable manner.
摘要:
A gas sensor and method of gas sensing, e.g., of a type as useful with downstream sensor elements for determining the plasma conditions (e.g., plasma etching end point) in a semiconductor etching facility that utilizes halogen-containing plasma and/or oxygen-containing plasma. Such sensor elements are capable of exhibiting temperature change in the presence of energetic gas species, e.g., fluorine, chlorine, iodine, bromine, oxygen, and derivatives and radicals thereof that are generated by the plasma, and correspondingly generating an output signal indicative of such temperature change for determination of the plasma conditions in the etching plasma processing facility.
摘要:
A gas detector and process for detecting a fluorine-containing species in a gas containing same, e.g., an effluent of a semiconductor processing tool undergoing etch cleaning with HF, NF3, etc. The detector in a preferred structural arrangement employs a microelectromechanical system (MEMS)-based device structure and/or a free-standing metal element that functions as a sensing component and optionally as a heat source when elevated temperature sensing is required. The free-standing metal element can be fabricated directly onto a standard chip carrier/device package so that the package becomes a platform of the detector.

Antimony, germanium and tellurium precursors useful for CVD/ALD of corresponding metal-containing thin films are described, along with compositions including such precursors, methods of making such precursors, and films and microelectronic device products manufactured using such precursors, as well as corresponding manufacturing methods. The precursors of the invention are useful for forming germanium-antimony-tellurium (GST) films and microelectronic device products, such as phase change memory devices, including such films.

摘要:
A method of improving the physical and/or electrical and/or magnetic properties of a thin film material formed on a substrate, wherein the properties of the thin film material are stress-dependent, by selectively applying force to the substrate during the film formation and/or thereafter during the cooling of the film in the case of a film formed at elevated temperature, to impose through the substrate an applied force condition opposing or enhancing the retention of stress in the product film. The method of the invention has particular utility in the formation of ferroelectric thin films which are grown at temperature above the Curie temperature, and which may be placed in tension during the cooling of the film to provide ferroelectric domains with polarization in the plane of the film.
摘要:
A full fill trench structure is described, including a microelectronic device substrate having a high aspect ratio trench therein and filled with silicon dioxide of a substantially void-free character and substantially uniform density throughout its bulk mass. A method of manufacturing a semiconductor product also is described, involving use of specific silicon precursor compositions for forming substantially void-free and substantially uniform density silicon dioxide material in the trench. The precursor fill composition may include silicon and germanium, to produce a microelectronic device structure including a GeO2/SiO2 trench fill material. A suppressor component may be employed in the precursor fill composition, to eliminate or minimize seam formation in the cured trench fill material.
摘要:
A multi-step method for depositing ruthenium thin films having high conductivity and superior adherence to the substrate is described. The method includes the deposition of a ruthenium nucleation layer followed by the deposition of a highly conductive ruthenium upper layer. Both layers are deposited using chemical vapor deposition (CVD) employing low deposition rates.
