    摘要: A precursor delivery system includes a flow path from a precursor container to a reaction space of a thin film deposition system, such as an atomic layer deposition (ALD) reactor. At least a portion of the flow path may be formed in one or more blocks of thermally conductive material forming an elongate thermally conductive body extending from the precursor container toward the reaction space. In some embodiments, a heater is thermally associated with the thermally conductive body to inhibit condensation of precursor vapor in the flow path. A high conductivity particle filter having inertial traps is preferably included for filtering particles from the precursor material. The particle filter preferably include a filter passage including turns and inertial traps adjacent the turns. In some embodiments, the filter passage and the inertial traps may be formed in the thermally conductive body between the precursor container and the reaction space.

    摘要: A shut-off type diaphragm valve adapted for use in an atomic layer deposition system includes a flexible diaphragm operable to flex between an open position whereby a valve passage is at least partially open and a closed position whereby a substantial portion of a first side of the diaphragm is pressed against a valve seat to thereby block the valve passage and facilitate heat transfer between the valve seat and the diaphragm. In some embodiments, a heating body thermally contacts the valve body and extends proximal to a second side of the diaphragm opposite the first side thereof to form a thermally conductive pathway that facilitates maintaining an operating temperature at the diaphragm. A thermally resistive member may be interposed between the valve passage and an actuator, such as a solenoid, for attenuating heat transfer between the valve passage and the actuator.

    摘要: The present invention relates to a method for enhancing uniformity of metal oxide coatings formed by Atomic Layer Deposition (ALD) or ALD-type processes. Layers are formed using alternating pulses of metal halide and oxygen-containing precursors, preferably water, and purging when necessary. An introduction of modificator pulses following the pulses of the oxygen-containing precursor affects positively on layer uniformity, which commonly exhibits gradients, particularly in applications with closely arranged substrates. In particular, improvement in layer thickness uniformity is obtained. According to the invention, alcohols having one to three carbon atoms can be used as the modificator.

    摘要: The invention relates to a multilayer material deposited by ALD. A multi-layer structure of a high refractive index material is deposited on a substrate using ALD at a temperature below about 450° C. Advantageous results are obtained when a high refractive index material A is coated with another material B after a certain thickness of material A has been achieved. Thus, the B barrier layer stops the tendency for material A to crystallize. The amorphous structure gives rise to less optical loss. Further, the different stress nature of materials A and B may be utilized to achieve a final optical material with minimal stress. The thickness of each material B layer is less than that of the adjacent A layer(s). The total effective refractive index of the high refractive index material A+B being shall be greater than 2.20 at a wavelength of 600 nm. Titanium oxide and aluminium oxide are preferred A and B materials. The structure is useful for optical coatings.
