GAS SUPPLY AMOUNT CALCULATION METHOD AND SEMICONDUCTOR DEVICE MANUFACTURING METHOD
Gas supply amount calculation method includes: calculating flow rate of first substance gas by subtracting flow rate of second substance gas from flow rate of mixed gas of the first and second substance gas flowing through gas supply path connected to processing container configured to perform film formation by atomic layer deposition method; calculating first integrated flow rate of the first substance gas over time in remaining plurality of cycles after elapse of a predetermined number of cycles immediately after start of the film formation over a plurality of cycles; calculating average integrated flow rate per cycle by dividing the first integrated flow rate by the number of the remaining plurality of cycles; and calculating total supply amount of the first substance gas in the plurality of cycles by adding multiplication value obtained by multiplying the average integrated flow rate by the predetermined number and the first integrated flow rate.

CLUSTER TOOLS, SYSTEMS, AND METHODS HAVING ONE OR MORE PRESSURE STABILIZATION CHAMBERS
In one aspect, a process operation is conducted at a first pressure in a process chamber, and an epitaxial deposition operation is conducted at an atmospheric pressure in an epitaxial deposition chamber. The atmospheric pressure is greater than the first pressure. The process chamber is mounted to a first mainframe that operates at the first pressure (a reduced pressure), and the epitaxial deposition chamber is mounted to a second mainframe that operates at the atmospheric chamber. In one aspect, the process chamber is a cleaning chamber (such as a pre-clean chamber) and the process operation is a cleaning operation. In one aspect, the process chamber is an atmospheric pressure epitaxial deposition chamber and the process operation is an atmospheric pressure epitaxial deposition operation.
SUBSTRATE SUPPORTS FOR SEMICONDUCTOR PROCESSING SYSTEMS
A substrate support includes a disc body with an upper surface and an opposite lower surface arranged along a rotation axis. The upper surface has a circular concave portion extending about the rotation axis, an annular ledge portion extending circumferentially about the concave portion, and an annular rim portion extending circumferentially about the ledge portion connecting to the concave portion of the disc body by the ledge portion of the disc body. The ledge portion slopes downward radially outward from the rotation axis to seat a substrate on the disc body such that a beveled edge of the substrate is cantilevered above the ledge portion of the upper surface of the disc body. Substrate support assemblies, semiconductor processing systems, and film deposition methods are also described.
METHOD OF TRANSPORTING WORKPIECE AND PROCESSING APPARATUS
A method of transporting a workpiece includes steps of: (a) adjusting an inclination of a stage including a placement surface on which the workpiece is to be placed such that the placement surface is inclined with respect to a horizontal plane; (b) receiving the workpiece from a transport apparatus configured to transport the workpiece by raising lift pins provided in the stage, before or after step (a); (c) placing the workpiece on the inclined placement surface by performing at least one of lowering the lift pins and raising the stage; and (d) adjusting the inclination of the stage such that the placement surface on which the workpiece is placed is parallel to the horizontal plane.
BOTTOM COVER PLATE TO REDUCE WAFER PLANAR NONUNIFORMITY
Embodiments of the disclosure provided herein generally relate to a bottom cover plate (BCP) that enables control of radiation loss from a heating element inside a chamber for processing a substrate. The heating element is used to heat the substrate before or during processing and may heat the substrate unevenly due to uneven heat losses within the chamber. For example, the uneven heating of the substrate may result in uneven deposition of a material on the substrate, which may result in excess processing to correct the deposition or wasted product from disposing of improperly processed substrates. The BCP may be used to correct the uneven heating of the substrate.
Translating and rotating chuck for processing microelectronic substrates in a process chamber
Cleaning systems and methods for semiconductor fabrication use rotatable and translatable chuck assemblies that incorporate a compact drive system to cause chuck rotation. The system uses an offset drive gear that drives a ring gear. This reduces components whose friction or lubricants might generate undue contamination. The low friction chuck functionality of the present invention is useful in any fabrication tool in which a workpiece is supported on a rotating support during a treatment. The chuck is particularly useful in cryogenic cleaning treatments.
Chuck For Processing Semiconductor Workpieces At High Temperatures
A chuck for heating and clamping a workpiece, such as a semiconductor workpiece, is disclosed. The chuck is configured to allow the workpiece to be heated to temperatures in excess of 600° C. Further, while the workpiece is heating, the components that make up the chuck may be maintained at a much lower temperature, such as room temperature. The chuck includes a housing, formed as a hollow cylinder with sidewalls and an open end. Electrodes are disposed at the top surface of the sidewalls to clamp the workpiece. A heat source is disposed in the cavity and emits radiated heat toward the workpiece. A clamp ring may be used to secure the workpiece. In some embodiments, a thermal sensor is used to monitor the temperature of the workpiece.
