Semiconductor Process Gas Control
Flow, pressure, valve and communication interfaces organized from process media and equipment actions.
Problem Definition
Start from the Operating Boundaries
Common-manifold pressure changes, recipe switching and downstream load jointly act on gas output, so selection must be built on real operating conditions.
Solution Inputs
Operating Conditions to Confirm
Media and Recipe
Gas names, setpoint ranges, switching sequence and purge requirements.
Pressure Boundaries
Supply, downstream and abnormal-state pressure conditions.
Equipment Interfaces
Installation space, connections, power, communication and alarm logic.
System Components
Organizing Functional Units Around the Task
Flow and Pressure Actuation
Match flow controllers or pressure controllers to the controlled object.
Isolation and Connection
Organize valves and modular interfaces per cleanliness and maintenance requirements.
Equipment Control
Unify setpoint, feedback, status and fault information.
Implementation Path
Solution Workflow
步骤 1
Confirm Inputs
Record media, boundary conditions, actions and equipment interfaces.
步骤 2
Form the Configuration
