摘要: A dry etching method capable of performing fine patterning. A sample substrate is fixedly disposed on a table in a reactant chamber. Gas plasma produced by a gas plasma generator is introduced into the reactant chamber, and excitation light, that is, light capable of exciting inner shell electrons of constituent atoms of the substrate, is irradiated onto the substrate from above the substrate. In the optical path of the excitation light is disposed a mask. The substrate is irradiated with the light in response to a pattern designated by the mask. The excitation light has an energy for exciting electrons of constituent atoms of the substrate. Upon arrival of the light in etched regions, the electrons of the substrate are excited. As a result, etching is effected by the contact of the excited electrons with the gas plasma, and the rate of this etching is greatly enhanced. Since the electrons of the substrate in masked areas are not excited, the masked areas become hardly subjected to etching by the contact of the gas plasma, whereby the pattern of the mask is transferred to the substrate with high accuracy, whereby fine patterns are formed.

摘要: A process wherein a thin film metal (e.g. tungsten) is anisotropically etched under plasma bombardment conditions by using a feed gas mixture which includes a fluorine source (such as SF.sub.6) plus a fluorosilane (e.g. SiF.sub.4), plus a bromine source (such as HBr), plus a weak oxygen source such as carbon monoxide. This chemistry provides anisotropic high rate fluoro-etching with good selectivity to photoresist.

摘要: An improved semiconductor device manufacturing system and method is shown. In the system, undesirable sputtering effect can be averted by virtue of a combination of an ECR system and a CVD system. Prior to the deposition according to the above combination, a sub-layer can be pre-formed on a substrate in a reaction chamber and transported to another chamber in which deposition is made according to the combination without making contact with air, so that a junction thus formed has good characteristics.

摘要: Techniques herein include systems and methods for fine control of temperature distribution across a substrate. Such techniques can be used to provide uniform spatial temperature distribution, or a biased spatial temperature distribution to improve plasma processing of substrates and/or correct characteristics of a given substrate. Embodiments include a plasma processing system with temperature control. Temperature control systems herein include a primary heating mechanism to heat a substrate, and a secondary heating mechanism that precisely modifies spatial temperature distribution across a substrate being processed. At least one heating mechanism includes a digital projection system configured to project a pattern of electromagnetic radiation onto or into a substrate, or through the substrate and onto a substrate support assembly. The digital projection system is configured to spatially and dynamically adjust the pattern of electromagnetic radiation and selectively augment heating of the substrate by each projected point location.

摘要: A film thickness distribution exists in a substrate plane after CMP step. This film thickness distribution results in, for example, variation in gate threshold value voltages of metal gates, and causes variation in element characteristics. It is an object of the present invention to easily improve the film thickness distribution processed by this CMP step.By using the ion beam etching method after the CMP step, the film thickness distribution in the plane of the substrate 111 is corrected. More specifically, when the ion beam etching is performed, the plasma density in the plasma generation chamber 102 is caused to be different between a position facing a central portion in the plane of the substrate 111 and a position facing an outer peripheral portion, so that the etching rate in the central portion in the plane of the substrate 111 and the etching rate in the outer peripheral portion in the substrate plane 111 are caused to be different.

摘要: A plasma generation process that is more optimized for vapor deposition processes in general, and particularly for directed vapor deposition processing. The features of such an approach enables a robust and reliable coaxial plasma capability in which the plasma jet is coaxial with the vapor plume, rather than the orthogonal configuration creating the previous disadvantages. In this way, the previous deformation of the vapor gas jet by the work gas stream of the hollow cathode pipe can be avoided and the carrier gas consumption needed for shaping the vapor plume can be significantly decreased.
