A method for forming a doped layer is disclosed. The doped layer may be used in a NMOS or a silicon germanium application. The doped layer may be created using an n-type halide species in a n-type dopant application, for example.
COATING EQUIPMENT
Provided by the invention disclosure is a coating equipment. The coating equipment comprises a reaction chamber body provided with a reaction chamber, a gas supply part configured to supply gas to the reaction chamber, a pumping device configured to communicate with the reaction chamber, a pulse power supply adapted to provide the reaction chamber body with a pulsed electric field and a radio frequency power supply adapted to provide the reaction chamber body with a radio frequency electric field, wherein the reaction chamber is adapted to accommodate a plurality of workpiece. When the pulse power supply and the radio frequency power supply are turned on, the gas in the reaction chamber body is ionized under the radio frequency electric field and the pulsed electric field to generate plasma, and the plasma is deposited on the surface of the workpieces.
VAPOR DEPOSITION DEVICE AND VAPOR DEPOSITION METHOD
A vapor deposition device is provided that can suppress an influence on an epitaxial layer which is caused by a position of a lift pin without adjusting an upper and lower heating ratio of a wafer. A reaction chamber is provided with a susceptor on which a carrier is placed, and a carrier lift pin which moves the carrier vertically relative to the susceptor; and the carrier lift pin is installed outside of an outer edge of the wafer when a state where the carrier supporting the wafer is mounted on the susceptor is viewed in a plan view.
ELECTRODE SUPPORT, SUPPORTING STRUCTURE, SUPPORT, FILM COATING APPARATUS, AND APPLICATION
The present disclosure provides an electrode support, a supporting mechanism, a support, a film coating apparatus, and an application. The electrode support is applied to the film coating apparatus. The film coating apparatus allows coating of at least one to-be-coated workpiece. The film coating apparatus comprises a reaction chamber and a pulse power supply; the pulse power supply is used for providing a pulse electric field in the reaction chamber. The electrode support comprises support members arranged in multiple layers; the support member of each layer is separately retained at a preset spacing; at least one layer of the support member is conductively connected to the pulse power supply to serve as a negative electrode of the pulse power supply. The electrode support can uniformly load the to-be-coated workpiece and can be used as an electrode, and wiring between the electrode support and an external power supply is simple.
SEMICONDUCTOR PROCESSING CHUCKS FEATURING RECESSED REGIONS NEAR OUTER PERIMETER OF WAFER FOR MITIGATION OF EDGE/CENTER NONUNIFORMITY
Chucks for supporting semiconductor wafers during certain processing operations are disclosed. The chucks may include a recessed region near the outer perimeter of the wafer that has one or more surfaces that face towards the wafer but are recessed therefrom so as to not contact the wafer around the perimeter of the wafer. The use of such a recessed region prevents direct thermally conductive contact between the chuck and the wafer, thereby allowing the wafer to achieve a more uniform temperature distribution in certain process conditions. This has the further effect of causing certain processing operations to be more uniform with respect to edge-center deposition (or etch) layer thickness.
USE OF A CVD REACTOR FOR DEPOSITING TWO-DIMENSIONAL LAYERS
A two-dimensional layer is deposited onto a substrate in a CVD reactor, in which a process gas is fed into a process chamber. The process gas in the process chamber is brought to the substrate, and the substrate is heated to a process temperature. After a chemical reaction of the process gas, the layer forms on the surface. During or after the heating of the substrate to the process temperature, the process gas with a first mass flow rate is initially fed into the process chamber and then, while the substrate surface is being observed, the mass flow rate of the process gas is increased to a rate at which the layer growth begins, and subsequently the mass flow rate of the process gas is increased by a predetermined value, during which the layer is deposited. The beginning of the layer growth is identified by observing measurements from a pyrometer.
MODULATION OF OXIDATION PROFILE FOR SUBSTRATE PROCESSING
Methods and apparatuses are provided herein for oxidizing an annular edge region of a substrate. A method may include providing the substrate to a substrate holder in a semiconductor processing chamber, the semiconductor processing chamber having a showerbead positioned above the substrate holder, and simultaneously flowing, while the substrate is supported by the substrate holder, (a) an oxidizing gas around a periphery of the substrate and (b) an inert gas that does not include oxygen through the showerhead and onto the substrate, thereby creating an annular gas region over an annular edge region of the substrate and an interior gas region over on an interior region of the substrate; the simultaneous flowing is not during a deposition of a material onto the substrate, and the annular gas region has an oxidization rate higher than the interior gas region.
