Abstract:
PROBLEM TO BE SOLVED: To provide a wafer port which holds wafers during processing so that the wafers are arranged at intervals in the vertical direction. SOLUTION: The wafer port, which holds wafers during processing so that the wafers are arranged at intervals in the vertical direction, includes a plurality of holding positions separated in the vertical direction to receive and hold the wafer substantially horizontally. The holding position can be accessed from the front of the wafer port, thereby, the wafer can be inserted and removed. At least one holding position includes a backward supporter to engage with the backward portion of the wafer and two side supporters to engage with side portions opposite to each other. The backward supporters are located at position lower than the two side supporters to correct at least partially the state where the front portion of the wafer inserted near the front of the wafer port is hung due to its gravity.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for depositing a plurality of layers of different materials in a sequential process within a deposition chamber. SOLUTION: A substrate is provided in a deposition chamber. A plurality of cycles of a first atomic layer deposition (ALD) process is sequentially conducted to deposit a layer of a first material on the substrate in the deposition chamber. These first cycles include pulsing a cyclopentadienyl metal precursor. A plurality of cycles of a second ALD process is sequentially conducted to deposit a layer of a second material on the layer of the first material in the deposition chamber. The second material comprises a metal different from the metal in the cyclopentadienyl metal precursor. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a system and method for efficiently executing the installation procedure of a semiconductor manufacturing apparatus. SOLUTION: The system and the method for installing the semiconductor manufacturing apparatus include several modules, each of which is provided with a plurality of module supporting feet at a bottom side. The system and the method include a supporting point reduction frame having an upper side and a bottom side, the frame at the upper side is provided with a plurality of first supporting points, and each foot of the module of the semiconductor manufacturing apparatus corresponds with a first supporting point. The supporting point reduction frame at the bottom side is provided with a plurality of second supporting points, and the total number of the module supporting feet exceeds the number of second supporting points. The stiffness of the supporting point reduction frame is such that, during transportation, deviations in the relative positions of the modules mounted on the supporting point reduction frame remain within specified transportation limits.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for reducing a drop in deposition speed after the cleaning of a reaction chamber. SOLUTION: A method for obtaining a stable and high deposition speed in a reaction chamber is provided after the cleaning of the reaction chamber. The method includes steps of cleaning the chamber, precoating the inner surface of the reaction chamber with inorganic compositions, and then depositing an organic layer on a workpiece using the precoated chamber.

Abstract:
PROBLEM TO BE SOLVED: To provide a heat insulating wafer-boat support pedestal which is not bulky and capable of being used at ultra-high temperatures in a vertical furnace, for example, at 1,000°C or higher. SOLUTION: The pedestal 100 for use in a high-temperature vertical furnace for processing semiconductor wafers is provided with a closure and heat insulating materials for the lower end of the furnace, and is a wafer boat support. The pedestal 100 comprising quartz-enveloped heat insulating materials (130, 132), supports a wafer boat at a boat support level 113, and is provided with an upper section 102 disposed above the boat support level 113. The upper section 102 comprises an enveloped heat insulating material 130. The envelope of the upper section 102 is also formed of quartz, and the insulating material 130 in the upper section 102 has thermal conductivity lower than that of the insulating material 132 in a lower quartz-enveloped section 104.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for treatment of a substrate in which no scratch is made on a surface of the substrate when it is heat-treated while an inner region thereof is still supported. SOLUTION: A substrate holder 15 for a vertical furnace is configured to support a substrate 10 in a slot at inner portions of the substrate, rather than solely at the edges. The substrate holder allows sufficient clearance above substantially the entire top surface of the substrate that a substrate deflection or bow, induced by thermal stresses during loading and unloading of the substrate holder into and out of the furnace, can be accommodated without the substrate touching a support member 30 of the substrate holder, for a given amount of free space in a wafer slot, in the relationship with maximum loading and/or unloading temperatures for avoiding scratching. Consequently, the scratching of the substrate is prevented under the given loading/unloading temperatures. COPYRIGHT: (C)2004,JPO
