Abstract:
PROBLEM TO BE SOLVED: To provide a substrate support assembly where a substrate holder support section is securely fixed to a rotating shaft with respect to a force applied to a rotative direction. SOLUTION: The substrate holder support section (spider) 10 has a plurality of support arms 12 extended toward the radial outside and upper side from a central socket 14 that supports the lower side of the substrate holder such as susceptor. The support assembly 8 comprises an elbow-shaped retention member 22 having an engagement section and a fixed section 32, and the engagement section is inserted in an opening 26 if positions of a socket opening section 26 and the cutout section of a shaft 20 are aligned to form a path. By engaging both the socket opening 26 and the cutout section of the shaft 20, the spider socket 14 is fixed to the shaft 20, thereby enabling the prevention of rotation between both, namely, revolving slide.

Abstract:
PROBLEM TO BE SOLVED: To provide a chemical vapor deposition method using trisilane and a halogen-containing etchant source (such as chlorine) to selectively deposit a Si-containing film over a selected region of a mixed substrate.SOLUTION: A dopant source may be intermixed with the trisilane and the etchant source to selectively deposit the doped Si-containing film. This selective deposition method is useful in a variety of applications, such as semiconductor manufacturing.
Abstract:
PROBLEM TO BE SOLVED: To solve such a problem that poor planarization in a multilayer process of semiconductor device fabrication may induce problems in a photolithography process, especially poor planarization at the initial deposition step tends to be amplified through higher layers in semiconductor device fabrication, and to provide a deposition method of a blanket layer in the initial stage of semiconductor device fabrication process where this point is improved.SOLUTION: The blanket deposition method of an SiGe film 30 includes a step for mixing silicon source, germanium source and etchant in order to form a gaseous precursor mixture. Furthermore, the gaseous precursor mixture is made to flow on a substrate 10 under conditions of chemical vapor deposition, and a blanket layer 30 exhibiting excellent planarity is deposited by a method of depositing epitaxial SiGe on the substrate 10 regardless of whether there is a pattern or not.
Abstract:
PROBLEM TO BE SOLVED: To provide a stressor for engineered strain on a channel and a forming method thereof. SOLUTION: A semiconductor substrate has recesses filled with heteroepitaxial silicon-containing material with different portions having different impurity concentrations. Strained layers can fill recessed source/drain regions in a graded, bottom-up fashion. Layers can also line recess sidewalls with one concentration of strain-inducing impurity and fill the remainder to the recess with a lower concentration of the impurity. In the latter case, the sidewall liner can be tapered. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a process chamber capable of withstanding high temperature, low pressure processes, and having improved wafer temperature uniformity and gas flow characteristics. SOLUTION: The chamber has a vertical-lateral lenticular cross-section with a wide horizontal dimension and a shorter vertical dimension between biconvex upper and lower walls 12, 14. A central horizontal support plate 40 is provided between two lateral side rails 16, 18 of the chamber. The support plate segregates the process chamber into an upper region and a lower region 66, 68, with purge gas being introduced through the lower tube into the lower region to prevent unwanted deposition therein. A temperature compensation ring surrounds the susceptor and is constructed of a material absorbing heat at an efficiency higher than the case of the chamber walls. A gas injector includes a plurality of independently controlled channels disposed laterally across the chamber, the channels merging at an outlet of the injector to allow mixing of the adjacent longitudinal edges of the separate flows well before reaching the wafer.

Abstract:
PROBLEM TO BE SOLVED: To improve a service life of a lamp, mostly on a lamp filament, for use in a semiconductor processing reactor in which a high energy radiation heating is conducted. SOLUTION: The lamp is provided with a supporting part 42 which is improved so that a lamp filament 14 can be placed in a lamp sleeve in an axial direction. The supporting part 42 as shown in a drawing is a spiral coil having a central part of a small diameter contacting the filament 14. At both ends of a filament contacting part, the coil is expanded to a larger diameter so that it contacts an inner wall of a quartz sleeve which houses the filament 14. Therefore, the supporting part 42 appears in an H shape in a side view. The lamp filament 14 is also provided with an expansion compensating part 74 on both sides of the central part 72. A filament wire of the expansion compensating part 74 is wound and becomes a coil of a larger diameter as compared with the coil in the central part 72 and of a wider gap between winding wires. The expansion compensating part 74 is preferably elastic in compression and thus a heat expansion of the filament 14 while in operation can be absorbed and a short circuit of the filament 14 can be prevented throughout neighboring wires.

Abstract:
PROBLEM TO BE SOLVED: To provide a system and a method for accurately positioning a substrate by detecting and correcting deviations of a wafer and the other substrate from respective reference positions during the carriage of them by a robot. SOLUTION: The system includes at least two fixed reference points 302, 304. The reference points 302, 304 are allowed to have fixed positional relation with a working tool or an end effector 224. When a robot arm moves the end effector 224 and the substrate 210 along a passage, a camera 306 captures images of the edge of the substrate 210, and the reference points 302, 304. Two or more cameras 306 can also be arranged. Then the computer can calculate the positional drift of the substrate 210 from its expected or center position on the end effector 224, on the basis of these read result and the drift can be corrected in subsequent robot arm movement.

Abstract:
An improved thermocouple assembly for providing a temperature measurement is provided. The thermocouple assembly includes a sheath having a measuring tip, a support member received within the sheath, and first and second wires disposed within the support member. An end of each of the first and second wires are fused together to form a thermocouple junction therebetween. A recessed region is formed in a distal end of the support member, and the thermocouple junction is fixedly located at the base of the recessed region such that the recessed region maintains the thermocouple junction in a substantially fixed position relative to the measuring tip of the sheath.
