Abstract: In a method for depositing a layer of amorphous hydrogenated silicon carbide (SiC:H), a gas mixture comprising a reactive gas to inert gas volume ratio of 1:12 to 2:3 is introduced into a reaction chamber of a plasma-enhanced chemical vapor deposition apparatus. The reactive gas has a ratio of Si of 50 to 60, C of 3 to 13, and H of 32 to 42 at %. The inert gas comprises i) a first inert gas selected from helium, neon and mixtures; and ii) a second inert gas selected from argon, krypton, xenon and mixtures. The reaction plasma is at a power frequency of 1-16 MHz at a power level of 100 W to 700 W. The resulting layer exhibits a refractive index of not less than 2.4 and a loss of not more than 180 dB/cm at an indicated wavelength within 800 to 900 nm.

Abstract: Methods that include directing an incident beam towards a substrate, the substrate having one or more features formed thereon wherein the incident beam has a wavelength from about 10 ?m to about 10 mm, and the incident beam interacts with the substrate to form a modulated beam; varying one or more characteristics of the incident beam while directed towards the substrate; detecting the modulated beam while varying the one or more characteristics of the incident beam to collect a spectrum; and determining at least one spatial metric of the at least one feature based on the collected spectrum.

Abstract: Fluid supply systems for storage and dispensing of chemical reagents and compositions, e.g., high purity liquid reagents and chemical mechanical polishing compositions used to manufacture microelectronic device products, having capability for detection of an empty or near-empty condition when the contained liquid is at or approaching depletion during dispensing operation. Fluid delivery systems employing empty detect arrangements are described, including pressure transducer monitoring of dispensed material intermediate the supply package and a servo-hydraulic dispense pump, or monitoring of dispenser chamber replenishment times in a dispenser being replenished on a cyclic schedule to flow material from the dispenser to a downstream tool utilizing the dispensed material.

Abstract: A method is disclosed for measuring the dose and energy level of ion implants forming a shallow junction in a semiconductor sample. In the method, two independent measurements of the sample are made. The first measurement monitors the response of the sample to periodic excitation. In the illustrated embodiment, the modulated optical reflectivity of a reflected probe beam is monitored to provide information related to the generation of thermal and/or plasma waves in the sample. A second spectroscopic measurement is also performed. This measurement could be either a spectroscopic reflectometry measurement or a spectroscopic ellipsometry measurement. The data from the two measurements are combined in a manner to yield information about both the dose (concentration) of the dopants as well as the energy used to inject the dopants in the semiconductor lattice. The method will useful in controlling the formation of shallow junctions.

In a preferred embodiment, the principal combination includes a thermal wave measurement and a spectroscopic ellipsometric measurement. These measurements are used to characterize ion implantation processes in semiconductors over a large dosage range.
