Semiconductor

As the cornerstone of the modern technology industry, semiconductor manufacturing pursues extreme precision in its processes. From wafer processing and lithography to etching, thin-film deposition, and packaging and testing, every step must be carried out in an ultra-high-purity environment that is nearly exacting. Even minor fluctuations in pressure parameters can, at best, lead to non-uniform thin films or deviations in etching rates, and at worst, directly result in the scrapping of an entire batch of wafers—making pressure control a critical factor affecting yield. Particularly in the front-end processes, the precise control of ultra-pure, highly toxic, and strongly corrosive specialty gases such as SiH₄, PH₃, AsH₃, ClF₃, and HF places nearly extreme demands on the performance of pressure sensors.

Traditional pressure sensors often pose significant challenges—such as insufficient material purity, poor corrosion resistance, noticeable long-term drift, and inability to withstand high temperatures—which have become weak links that hinder yield improvement and process safety. In the context of constrained supply chains, these issues further highlight their "bottleneck" nature. To meet the stringent demands of semiconductor manufacturing for pressure measurement, SunnoMinds has launched the S270 series of ultra-high-purity pressure transmitters, centered around its independently developed nanofilm technology. From material selection and structural design to manufacturing processes, this product fully embodies the principles of "ultra-high purity, strong corrosion resistance, and stable output." Not only does it comply with SEMI standards, but it also achieves breakthroughs in key performance indicators such as helium leak rate, temperature adaptability, and long-term stability. As a result, it provides semiconductor equipment and production lines with a stable, reliable, and domestically controllable pressure measurement solution, helping customers overcome process bottlenecks and enhance their manufacturing competitiveness.

Relevant typical cases

The S270 series ultra-high-purity pressure transmitters developed by Sunno Alliance feature pressure sensing elements and main structural components made entirely of highly corrosion-resistant alloy materials. Combined with a specialized internal surface treatment process, these transmitters can effectively resist the corrosive effects of various specialty gases, thereby eliminating at the source any risk of metal ion contamination. The material purity of this product series exceeds the SEMI F20 standard, reaching aerospace-grade levels. Moreover, the series outperforms comparable international products in key performance indicators such as helium leak rate, operating temperature range, and measurement accuracy. Based on our deep understanding of local manufacturing needs, we are able to respond swiftly to customized development requirements and continuously provide highly reliable, independently controllable ultra-high-purity pressure measurement solutions for well-known domestic semiconductor companies such as Xinkailai.
