摘要:
A process gas is provided to a reactor volume of a semiconductor processing reactor through gas injector ports (120) of a gas ring (106). The process gas flows horizontally from the gas injector ports across a principal surface of a rotating susceptor (108) to exhaust ports (122) of the gas ring. The spent process gas is removed from the reactor volume through the exhaust ports (122).

A multi-layer RTP reactor susceptor structure includes a which has a multiplicity of thin components that are preferably silicon carbide, graphite, or silicon carbide coated graphite with a thickness less than about 6 mm, with an emissivity such that the first layer radiates heat, and with thermal heat transfer characteristics such that the first layer facilitates maintaining a substrate or substrates supported by the susceptor at a uniform temperature, and facilitates maintaining uniform process gas characteristics over the substrates. A second layer of the susceptor is transparent to the heat source of the RTP reactor and provides a rigid, stable platform for the first layer.
摘要:
A cluster tool layer thickness measurement apparatus is part of a reactor cluster that includes a plurality of substrate processing reactors arranged around a sealed chamber in which a robot is located. The cluster tool layer thickness measurement apparatus is also mounted on the sealed chamber. After a layer is deposited on a substrate in one of the reactors, the robot removes the substrate from the reaction chamber of the reactor and places the substrate directly in the cluster tool layer thickness measurement apparatus on a substrate support. A carriage assembly moves the substrate support and consequently the substrate under an optical thickness measurement assembly. Optical thickness measurement assembly generates a signal representative of the thickness of the layer at one point that is transmitted to a monitor computer. After the measurement is completed, the carriage assembly moves the substrate so that the thickness of a layer on the substrate is measured at each of a plurality of locations.

A gas jet assembly includes a gas injector having a longitudinal axis, a first motor coupled to the gas injector and a second motor coupled to the gas injector. The first motor controls a position of the gas injector along the longitudinal axis of the gas injector. The second motor controls the angular position of the gas injector around the longitudinal axis of the gas injector.

摘要:
A semiconductor processing system includes a reactor (314) and a dispersion head (330) within the reactor. During use, process gas is supplied to the dispersion head. The process gas flows through distributors (332A to 332E) of the dispersion head and into the reactor. The process gas contacts substrates (316) in the reactor thus forming a layer on the substrate. Use of the dispersion head reduces and/or eliminates turbulence and recirculation in the flow of the process gas through the reactor. This results in the formation of layers on the substrates having excellent thickness uniformity. This also allows realization of an abrupt transition between layers formed on the substrates.
