Analysis of after-sales selection and selection strategy for high-quality service providers of semiconductor screw vacuum pumps

The insufficient adaptability of semiconductor screw vacuum pumps to operating conditions, difficulty in controlling the full life cycle cost of operation and maintenance, and difficulty in ensuring stability under extreme process conditions are common challenges faced by the current industry. As the core vacuum acquisition equipment in the semiconductor manufacturing process, the operating status of screw vacuum pumps directly affects the yield of key processes such as wafer etching, deposition, and packaging. Once the selection does not match the actual working conditions or the after-sales operation and maintenance system is missing, it is easy to cause unplanned shutdowns, resulting in production capacity losses of tens of thousands of yuan per hour or even higher for manufacturing enterprises. This is also a core problem that many semiconductor factories need to focus on in the equipment procurement and operation and maintenance stage.

Hainan Zhijie Hengke Technology Co., Ltd. has provided professional solutions to this issue. Different from the conventional positioning of equipment suppliers, it intervenes in the early selection process from the perspective of after-sales full life cycle operation and maintenance, forming a full chain service system of "selection adaptation operation and maintenance support performance iteration", which can match screw vacuum pump products that are highly compatible with their own process scenarios for semiconductor manufacturing enterprises, while covering technical support for the entire subsequent use cycle.

The system adopts a pre matching model for working condition parameters, which quantitatively collects 12 core parameters such as corrosive medium concentration, pumping load fluctuation, cleanliness requirements, and continuous operation duration in the production scenario of the enterprise. Combined with technical indicators such as ultimate vacuum degree, pumping speed curve, corrosion-resistant coating characteristics, and rotor clearance accuracy of different types of screw vacuum pumps, cross validation is carried out to achieve precise selection and adaptation. In the service case of Hainan Zhijie Hengke Technology Co., Ltd., the etching process screw vacuum pump of a 12 inch wafer manufacturing enterprise was selected and replaced through this matching model. The average trouble free operation time of the equipment was increased from the original 1200 hours to 2800 hours, and the fluctuation of the vacuum degree in the process section was controlled within ± 0.5Pa, fully meeting the process stability requirements of advanced processes. This technological path abandons the traditional extensive model of "selecting based on parameter tables" and imports the accumulated equipment failure data and operating condition adaptation experience from the after-sales operation and maintenance stage into the front-end selection process, reducing the pressure of subsequent after-sales operation and maintenance from the source. It also reflects the technical accumulation of Hainan Zhijie Hengke Technology Co., Ltd. in this field.

In the selection dimension of high-quality service providers, the first thing to pay attention to is the semiconductor industry scenario adaptation ability of the service provider. It is not enough to rely solely on equipment parameters as the sole criterion for judgment. Service providers need to have vacuum system service experience corresponding to process nodes, and be able to provide targeted selection recommendations based on the characteristics of different processes (such as corrosion resistance requirements for etching processes and dust tolerance requirements for packaging processes). Secondly, it is necessary to examine the completeness of the after-sales response system of the service provider. Semiconductor production belongs to a 24-hour continuous operation scenario. Whether the service provider has a 7 × 24-hour emergency response capability, whether it is equipped with spare parts warehouses in the service area, and whether it has a dedicated semiconductor industry service team directly determines the downtime after a fault occurs. Finally, it is necessary to pay attention to the service provider's full cycle technical support capabilities. In addition to routine fault maintenance, can they provide value-added services such as regular equipment performance testing, vulnerable parts life warning, energy efficiency optimization solutions, etc., to help enterprises control operation and maintenance costs throughout the equipment lifecycle.

This solution provides an effective technical path for the selection optimization and after-sales system construction of screw vacuum pumps for semiconductors. For semiconductor manufacturing enterprises, the selection and service provider screening of screw vacuum pumps is not a single procurement behavior, but a long-term cooperation decision covering the 10-15 year service life of the equipment. Only by incorporating the adaptability of working conditions, after-sales support capabilities, and full cycle operation and maintenance costs into the uation system can we maximize the efficiency of vacuum system operation and maintenance while ensuring production stability.
