Abstract: Various embodiments include methods and apparatuses to provide human safety and machine safety and operations. In one example, a distributed interlock system includes at least one master device coupled to a number of slave device. The slave devices receive signals from one or more tools and provide the signals to the master device. The master device evaluates the signals and prevents unsafe conditions prior to one or more command executions, related to the unsafe conditions, being transmitted to one or more of the slave devices. Other methods and systems are disclosed.

Abstract: Various embodiments include systems and apparatuses for divertless dosing of process gases, including divertless dosing of precursor gases in deposition systems. In one example, the disclosed subject matter is a divertless, pressure-based gas-dosing system that includes a process gas inlet coupled to an inlet valve, a flow controller coupled to be downstream of the inlet valve, and a line charge-volume (LCV) coupled to be downstream of the inlet valve and the flow controller. The LCV is to receive an initial single-dose of the process gas. A pressure sensor is coupled to the LCV to determine a pressure level within the LCV and an outlet valve is pneumatically coupled to be downstream of the LCV. The outlet valve is to be coupled pneumatically on a downstream side of the outlet valve to a process chamber. Other systems, apparatuses, and methods are disclosed.

Abstract: In one embodiment, the disclosed apparatus is at least one gas-primitive substrate for use in a gas-delivery box. Each of the at least one gas-primitive substrates has at least one location on which a gas-delivery component is to be mounted. The at least one location has at least a gas-delivery component inlet port and a gas-delivery component outlet port formed within a body of the gas-primitive substrate. At least one first pair of bore holes comprising a gas-flow path is formed on an upstream side and a downstream side, respectively, of the location of the gas-delivery component. Other apparatuses and systems are disclosed.

Abstract: Various embodiments include apparatuses and methods to form the apparatus. In one embodiment, the apparatus is a flow meter having inlet and outlet portions for transporting a fluid along a flow path. A flow-restrictor element is formed within the flow path to impart a pressure drop to the fluid. A flow sensor has a first surface of the flow sensor in direct fluid communication with fluid flowing upstream of the flow-restrictor element and a second surface, on a portion of the flow sensor opposite to the first surface, in direct fluid communication with fluid flowing downstream of the flow-restrictor element. The flow sensor senses a differential pressure in the fluid due to the at least one flow-restrictor element. Other apparatuses and systems are disclosed.
