Exemplary semiconductor processing systems may include a gas source coupled with a number of processing chambers. The gas source may include a controller. Each chamber may include an exhaust assembly having a foreline and a pump. The systems may include at least one abatement system coupled with each pump. The systems may include a plurality of exhaust lines that extend between each pump and the abatement system. The systems may include a dilution gas source coupled with each exhaust line. The systems may include a mass flow controller coupled between the dilution gas source and each exhaust line. The systems may include a temperature sensor coupled with each exhaust line between the pump and the abatement system. The temperature sensor may be communicatively coupled with the controller of the gas source, which may control flow of a gas to a chamber based on a measurement from the temperature sensor.

Interlock system for processing chamber exhaust assembly

Exemplary modular gas blocks may include a body having inlet and outlet ends. The body may define a portion of a first gas path along a length of the body and may define a second gas path along a width of the body. The first gas path may include channel segments defined within the body. The inlet end may define a gas inlet that is coupled with the first gas path. The body may define first fluid ports that are coupled with the first gas path. A fluid port of the first fluid ports may be coupled with the gas inlet. The first fluid ports may be coupled with one another via a respective channel segment. An upper surface may define a lateral fluid port that is spaced apart from a first fluid port along the width and is coupled with the first fluid port via the second gas path.

Modular multi-directional gas mixing block

A fluid delivery device is disclosed. The fluid delivery device includes a fluid flow meter. The fluid flow meter is enclosed in an insulated box. An intake is provided on the insulated box for providing a forced cooling gas flow over the fluid flow meter. An exhaust is provided on the insulated box from which the forced cooling gas exits the insulated box.

Thermally stable flow meters for precision fluid delivery

Exemplary substrate processing systems may include a lid plate. The systems may include a gas splitter seated on the lid plate. The gas splitter may define a plurality of gas inlets and gas outlets. A number of gas outlets may be greater than a number of gas inlets. The systems may include a plurality of valve blocks that are interfaced with the gas splitter. Each valve block may define a number of gas lumens. An inlet of each of the gas lumens may be in fluid communication with one of the gas outlets. An interface between the gas splitter and each of the valve blocks may include a choke. The systems may include a plurality of output manifolds seated on the lid plate. The systems may include a plurality of output weldments that may couple an outlet of one of the gas lumens with one of the output manifolds.
