<\/p>\nThe wave of fab expansion is not only pulling up process equipment procurement but also forcing a comprehensive upgrade of the ‘facility system’ behind it. Cleanroom class, ultra-pure water supply, specialty gas delivery, chemical and waste-liquid treatment are being built as the ‘new infrastructure’ of fabs; without these foundations, even the most advanced process equipment cannot run. Facility investment and construction schedule often decide whether a new fab can ramp up on time, making them a strategic rather than supporting concern, and early decisions about cleanroom class and utility capacity shape the fab’s economics for years to come.<\/p>\n
<\/p>\n
The cleanroom is the physical foundation of wafer manufacturing. As processes advance, cleanliness requirements move from Class 100 toward Class 10 and cleaner, correspondingly raising demands on ventilation filtration (FFU), temperature and humidity control, micro-vibration control and personnel cleansing. Wet tools such as cleaning and spin dryers must themselves sit in a high-class clean environment, because wafers after cleaning are extremely sensitive to ambient particles; if the environment is substandard, all upstream cleaning effort is wasted. Cleanroom class must therefore be matched to the cleanliness requirements of the process equipment inside, which drives the HVAC and filtration design of the whole bay.<\/p>\n
As noted earlier, wet cleaning depends heavily on ultra-pure water, while the drying step uses large volumes of high-purity nitrogen, hydrogen and other specialty gases. Expansion means UPW volume and specialty gas supply must be scaled up in step, requiring new or expanded central UPW plants and gas delivery systems, with stable, pure piping. UPW and specialty gases have become indispensable supporting major-line items in fab expansion, and their construction often precedes process equipment entry. Getting these utilities right is a prerequisite for commissioning any wet tool, and delays here can hold up an entire bay or even the whole fab ramp, which is why facility planning must lead rather than follow equipment procurement.<\/p>\n
Modern fab facility systems are deeply coupled with process equipment: the cleaning tool’s water intake, exhaust and waste liquid, and the spin dryer’s nitrogen and hot air, all need precise supply and handling from the facility. When planning a new line, process equipment selection must be synchronized with facility planning; domestic equipment vendors that provide mature equipment-to-facility interfaces greatly reduce customer build and commissioning cost. This coordination capability has become a new dimension of competition for domestic equipment makers, since a tool that does not cleanly interface with utilities can stall a whole new build.<\/p>\n
Facility systems are often built before process equipment arrives, and their design and construction schedule directly affect plant ramp-up. Take the UPW system: from raw-water pretreatment, reverse osmosis and ion exchange to terminal polishing, every stage must match fab capacity precisely; specialty gas pipe networks demand extremely high tightness and purity, and any leak can affect yield across the line. Meanwhile, as environmental and safety requirements tighten, chemical supply, waste recovery and exhaust treatment systems take a rising share of investment. Facilities are no longer an accessory to process equipment but core infrastructure deeply bound to capacity, yield and cost, and their quality determines whether a modern fab can run reliably over the long term.<\/p>\n
For customers planning new fabs or expansions, synchronizing process equipment with facility upgrades is the key to shortening build time and protecting the production schedule. Domestic wet-tool vendors that design for this facility coupling can win orders during the build phase rather than competing only at the equipment-selection stage. As Chinese fabs continue to expand, the facility-upgrade wave offers domestic cleaning and spin-dry suppliers a historical window to grow alongside the lines they serve, rather than after them.<\/p>\n
The cleanliness grade of the wet-process bay deserves special attention. Because wet tools handle large volumes of ultra-pure water and chemistry, the surrounding cleanroom must control not only airborne particles but also humidity, corrosive vapor and floor drainage. Excess humidity can condense on wafers after drying, while corrosive vapor from wet benches can damage nearby metrology and lithography tools. Facility designers therefore isolate wet bays with dedicated exhaust and maintain slightly lower pressure than adjacent bays, balancing the aggressive process environment with the need to protect dry tools. This careful zoning is a hallmark of a well-run fab and directly affects defect levels on cleaned wafers.<\/p>\n
In supporting wet-process equipment for expanding fabs, Hebei Zhongke Microelectronics Co., Ltd.<\/strong> designs its fully automatic single-wafer cleaning machine, 12-inch wafer spin dryer (SG-8-12-2D) and EFEM cleaning & drying system to interface cleanly with cleanroom, UPW and specialty gas systems, helping customers pair facility upgrades with reliable domestic wet-process equipment.<\/p>\n There is also a schedule dimension. Cleanroom construction, UPW plant commissioning and specialty gas piping often take longer than delivering the process tools themselves, so fab operators must order utility systems ahead of the equipment. A wet tool that arrives before its cleanroom, water and gas are ready simply idles, while a tool that interfaces cleanly with standardized utility connections can be commissioned quickly. This is why fabs increasingly ask equipment vendors for detailed utility diagrams early in the sales cycle, treating facility compatibility as a core purchase criterion rather than an afterthought.<\/p>\n In summary, facility systems are no longer the silent backbone of a fab but a strategic investment that determines ramp-up speed, operating cost and long-term yield. As Chinese fabs continue to expand, the vendors that win will be those that can deliver both process tools and a clear plan for integrating them into the broader facility ecosystem, rather than a standalone machine that customers must adapt around. The convergence of cleanroom, UPW, gas and waste treatment with wet-process equipment is now a core competitive battlefield, and the vendors that deliver integrated solutions early will win the build-phase orders. Domestic wet-process equipment makers that can ship tools with documented utility interfaces and cleanroom-compatible enclosures reduce the customer’s on-site engineering burden, which is increasingly decisive in tight-schedule expansions and often shortens overall ramp-up time by several weeks.
