High-purity Gas Panels Part 6: Valves as Flow Control

Typical "gas stick" in a semiconductor equipment gas panel. In part 6 of our blog series on the design of high purity semiconductor equipment, we'll be discussing gas valves.  While pressure regulators and mass flow controllers fine-tune the amount of gas delivered to a process, it is the manual and pneumatic valves that control the gas distribution system at the top level.  Valves...Read more

High-Purity Gas Panels Part 5: Safety Interlocks

The use of fail-safe hardware safety interlocks is a key tenet of semiconductor equipment engineering, to protect equipment and ensure personnel safety. The idea of fail-safe technology has existed for a long time, however, as engineers through history work to keep progressively more complex machines and operators safe.  An inventor named George Westinghouse, for instance, developed the...Read more

High-Purity Gas Panels Part 4: Gas Distribution Lines

For the first parts of this blog series, I wrote about the components and subsystems that makes up a high purity gas distribution system for a semiconductor process: Part 1 concerns gas panels, Part 2 gas storage, and Part 3 abatement and exhaust.  But while I’ve covered the components individually, I haven’t looked at the gas lines that fluidically connect them as necessary for a functional...Read more

High-purity Gas Panels Part 3: To Abatement and Exhaust

  Copyright Glew Engineering Consulting, Inc. In Part 1 and Part 2 of this blog series, I described some of the design challenges for the first parts of a gas distribution system: gas cabinets, liquid sources, valve manifold boxes (VMB) and the gas panel.  The gas cabinets store the gas cylinders, the valve manifold box controls the distribution of gases to one or more...Read more

High-purity Gas Panels Part 2: Gas Distribution in the Fab

As discussed in Part 1 of this blog series, gas panels are the control center for a process that requires gas phase flow.  As such, for any gas distribution system they are often the most complex and expensive component between the gas cylinder tank farm outside the semiconductor Fab and the process chamber.   The other parts of the system have their own requirements for safety and...Read more

High-purity Gas Panels Part 1: Introduction

  What's In a Semiconductor Gas Panel? A gas panel is a term of art in the semiconductor equipment (tool) and semiconductor processing industry.  Engineers refer to the box that controls the gases to a semiconductor processing chamber as a “gas panel.”  One way to think about it is to consider a system’s gas panel to be its “control panel” for the gases.  This the point where...Read more

Lean and Agile Mechanical Engineering: Part 3

Part 3 of 13: Welcome Changing Requirements   In this series of blogs, I’ve been looking at the strategies that agile software developers use to keep up with the ever-advancing cutting edge of their field, and taking stock of which of these ideals could be useful to a mechanical engineering firm.   The twelve principles laid out in the original Agile Development Manifesto [1] may...Read more
