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.

摘要:
The present invention relates to an electrode assembly useful for analyzing metal electroplating solutions. Such electrode assembly comprises a measuring electrode, preferably a rotating disc electrode or a microelectrode, and at least one of an in situ cleaning mechanism, a nucleation and metal growth optimization mechanism, and a voltage limiting mechanism. The present invention also relates to usage of such electrode assembly for in situ cleaning of the measuring electrode, nucleation and metal growth optimization, or voltage limitation.

A CMP composition containing 5-aminotetrazole, e.g., in combination with oxidizing agent, chelating agent, abrasive and solvent and a method of use. Such CMP composition may be diluted during the CMP polish to minimize the occurrence of dishing or other adverse planarization deficiencies in the polished copper, even in the presence of substantial levels of copper ions in the CMP composition and at the copper/CMP composition interface during CMP processing.
摘要:
A method of passivating a CMP composition by dilution and determining the relationship between the extent of dilution and the static etch rate of copper. Such relationship may be used to control the CMP composition during the CMP polish to minimize the occurrence of dishing or other adverse planarization deficiencies in the polished copper, even in the presence of substantial levels of copper ions in the CMP composition and at the copper/CMP composition interface.
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.

Tantalum compositions of Formulae I-V hereof are disclosed, having utility as precursors for forming tantalum-containing films. The tantalum compositions are amenable to usage involving chemical vapor deposition and atomic layer deposition processes, to form semiconductor device structures, including a dielectric layer, a barrier layer overlying the dielectric layer, and copper metallization overlying the barrier layer, wherein the barrier layer includes a Ta-containing layer including sufficient carbon so that the Ta-containing layer is amorphous. In one preferred implementation, the semiconductor device structure is fabricated by depositing the Ta-containing barrier layer, via CVD or ALD, from a precursor including a Ta alkylidene compound, at a temperature below 400° C., in a reducing or inert atmosphere.
