The Indispensable Multitasker
The manufacturing processes and practices required to produce to solid state technology are far more complex than the deceptively simple science that underpins semiconductor technology. But as Moore’s Law predicts that processing increases exponentially while price decreases inversely, so too does the return on investing in the new production technologies that make smaller and more efficient transistors and semiconductors. Of these technologies, new gas cabinets in particular have had an immeasurably positive effect on production safety and efficiency; in fact, many of the semiconductors produced for technologies like solar power and hand-held devices could not be feasibly produced without gas delivery anchored by automated cabinets.
A contemporary gas cabinet used in semiconductor manufacturing, in short, houses gas cylinders, along with a gas panel that automatically orchestrates all of the measuring, dispensation, mixing, and monitoring of gasses that would otherwise be overseen by individuals controlling each step of the process – someone to measure dispense gas through a first-stage regulator, another to oversee the creation of a precise mixture, another to monitor sensors for leakage, another to hold a fire extinguisher, and so forth. By incorporating on-board computing with a touch-screen interface, operators can control dispensing, mixing, and purging processes with the touch of a virtual button and automate even the most complicated processes.
Besides storing and automating the many complicated processes involved in creating finished chips – from creating silicon with thousands-of-degrees gas to creating an inert gas environment for welding – gas cabinets provide tremendous safety for an environment in which there is no room for error. Integrated leak sensors and fire safety mechanisms make response to any emergency automatic, rather contingent on less reliable human supervisors. By also keeping gas cylinders organized, cabinets allow manufacturers to keep gas inventory away from the production area, adding another element of protection to people, plant, property, and equipment.
As demand for semiconductors grows at a double-digit rate annually, the demand for cabinets and software that can handle new processes and greater capacities is also skyrocketing. This has created an opportunity for savvy buyers of production technology to scoop up perfectly good, refurbished cabinets at a fraction of the price of new ones.
In the same way that robotics revolutionized mechanical manufacturing processes, the emergence of the gas cabinet as a technology has revolutionized the chemical and thermal processes necessary to produce today’s semiconductors by combining safety with automation. It is safe to say that without this technology, many of the technologies we take for granted today would not be safe or profitable to make.
