| 20080224317 | STABLE SILICIDE FILMS AND METHODS FOR MAKING THE SAME - Highly thermally stable metal silicides and methods utilizing the metal silicides in semiconductor processing are provided. The metal silicides are preferably nickel silicides formed by the reaction of nickel with substitutionally carbon-doped single crystalline silicon which has about 2 atomic % or more substitutional carbon. Unexpectedly, the metal silicides are stable to temperatures of about 900° C. and higher and their sheet resistances are substantially unaffected by exposure to high temperatures. The metal silicides are compatible with subsequent high temperature processing steps, including reflow anneals of BPSG. | 09-18-2008 |
| 20090023302 | PROTECTIVE INSERTS TO LINE HOLES IN PARTS FOR SEMICONDUCTOR PROCESS EQUIPMENT - Inserts are used to line openings in parts that form a semiconductor processing reactor. In some embodiments, the reactor parts delimit a reaction chamber. The reactor parts may be formed of graphite. A layer of silicon carbide is deposited on surfaces of the openings in the reactor parts and the inserts are placed in the openings. The inserts are provided with a hole, which can accept another reactor part such as a thermocouple. The insert protects the walls of the opening from abrasion caused by insertion of the other reactor part into the opening. | 01-22-2009 |
| 20090291209 | APPARATUS AND METHOD FOR HIGH-THROUGHPUT ATOMIC LAYER DEPOSITION - Atomic layer deposition apparatus for depositing a film in a continuous fashion. The apparatus includes a process tunnel, extending in a transport direction and bounded by at least a first and a second wall. The walls are mutually parallel and allow a flat substrate to be accommodated there between. The apparatus further includes a transport system for moving a train of substrates or a continuous substrate in tape form, through the tunnel. At least the first wall of the process tunnel is provided with a plurality of gas injection channels that, viewed in the transport direction, are connected successively to a first precursor gas source, a purge gas source, a second precursor gas source and a purge gas source respectively, so as to create a tunnel segment that—in use—comprises successive zones containing a first precursor gas, a purge gas, a second precursor gas and a purge gas, respectively. | 11-26-2009 |
| 20090310648 | METHOD AND DEVICE FOR DETERMINING THE TEMPERATURE OF A SUBSTRATE - The publication discloses a method for determining a temperature of a substrate, comprising: providing a gas channel that is confined by at least one wall having a certain wall temperature; providing a substrate in said gas channel, proximate to the at least one wall, such that a gap exists between a surface of the substrate and the at least one wall; providing a gas flow with a certain mass flow rate through said gas channel, which gas flow extends at least partially through said gap; determining a pressure drop in the gas flow along the gas channel; and deriving from said pressure drop the temperature of said substrate using a pre-determined relation between the pressure drop along the gas channel, the wall temperature and the temperature of the substrate, at said mass flow rate. Also disclosed is a device for implementing the disclosed method. | 12-17-2009 |
| 20100209597 | SELECTIVE OXIDATION PROCESS - Silicon is selectively oxidized relative to a metal-containing material in a partially-fabricated integrated circuit. In some embodiments, the silicon and metal-containing materials are exposed portions of a partially-fabricated integrated circuit and may form part of, e.g., a transistor. The silicon and metal-containing material are oxidized in an atmosphere containing an oxidant and a reducing agent. In some embodiments, the reducing agent is present at a concentration of about 10 vol % or less. | 08-19-2010 |
| 20100210117 | SELECTIVE REMOVAL OF OXYGEN FROM METAL-CONTAINING MATERIALS - Oxygen is selectively removed from metal-containing materials in a partially-fabricated integrated circuit. In some embodiments, the partially-fabricated integrated circuit has exposed silicon and metal-containing materials, e.g., as part of a transistor. The silicon and metal-containing material are oxidized. Oxygen is subsequently removed from the metal-containing material by an anneal in an atmosphere containing a reducing agent. Advantageously, the silicon oxide formed by the silicon oxidation is maintained while oxygen is removed from the metal-containing material, thereby leaving a high quality metal-containing material along with silicon oxide. | 08-19-2010 |

| 20110268879 | APPARATUS AND METHOD FOR HIGH-THROUGHPUT ATOMIC LAYER DEPOSITION - Atomic layer deposition apparatus for depositing a film in a continuous fashion. The apparatus includes a downwardly sloping process tunnel, extending in a transport direction and bounded by at least two tunnel walls. Both walls are provided with a plurality of gas injection channels, whereby the gas injection channels in at least one of the walls, viewed in the transport direction, are connected successively to a first precursor gas source, a purge gas source, a second precursor gas source and a purge gas source respectively, so as to create a series of tunnel segments that—in use—comprise successive zones containing a first precursor gas, a purge gas, a second precursor gas and a purge gas, respectively. The downward slope of the process tunnel enables gravity to drive the floatingly supported substrates through the successive segments, causing the atomic layer deposition of a film onto the substrates. | 11-03-2011 |
