In the clean room of a semiconductor factory, a GETECH Stocker (wafer storage vertical warehouse) is moving FOUP/POD carriers containing wafers into the target Shelf (storage location) at a speed of 2m/s. At the same time, it interacts in real-time with the MES/MCS system via SECS/GEM protocol, automatically updating material status; when detecting fluctuations in oxygen concentration inside the warehouse, the N2 Purge system automatically starts, pulling environmental parameters back to the 'safe range'...

 

Today's semiconductor Stocker is no longer a simple 'material warehouse', but a core hub of the production line integrating full-process automation, system coordinated scheduling, and high cleanliness control, directly affecting wafer yield, production efficiency, and manufacturing costs.

 

 

 

Stocker's production line value: from 'storage equipment' to 'yield & efficiency accelerator'

 

 

 

GETECH Stocker can directly bring three core benefits to the production line: 'yield improvement, efficiency optimization, cost reduction', becoming an accelerator for promoting semiconductor intelligent manufacturing.

 

1. Improve wafer yield

Class100 cleanliness independently controllable: GETECH Stocker can stably maintain a Class100 clean environment, and the use of non-contact power supply, optical communication, etc., further meets the requirements for high cleanliness grade dust-free environments. Compared to traditional storage, the particle contamination rate during wafer storage is greatly reduced.

 

≤0.5G low vibration anti-damage design: Adopting high-reliability structural design, controlling vibration to ≤0.5G (advanced models can reach ≤0.35G), coupled with soft and wear-resistant carrier slots, significantly reducing wafer breakage rate, solving the problem of 'hidden damage' to wafers during storage.

 

7×24 hours unmanned access: GETECH Stocker integrates high-precision robotic arms (positioning accuracy ±0.05mm) with RFID/visual recognition systems, supporting 7×24 hours uninterrupted operation, while avoiding pollution risks from personnel entry and exit.

 

2. Optimize production efficiency

 

The 'machine idle time' in semiconductor production lines is the biggest efficiency waste, and GETECH Stocker effectively solves this problem through 'buffer adjustment' and 'dynamic scheduling':

 

Balance process capacity differences: When front-end processes like lithography and etching have higher capacity than packaging and testing, Stocker can temporarily store semi-finished wafers, avoiding front-end equipment shutdown due to 'material pile-up'; conversely, when back-end process demand surges, Stocker can quickly release materials, ensuring back-end equipment operates at full load.

 

Data-driven scheduling: Based on data from the MES/MCS system, Stocker can prepare to-be-processed material boxes in advance, precisely docking with machine Load Ports via OHT/AGV, reducing machine waiting time for materials, improving equipment utilization rate.

 

3. Reduce comprehensive costs

 

Labor cost savings: Stocker's single material access efficiency is 4 times that of manual operation, a single production line can reduce 3-5 storage operators, significantly lowering labor costs.

 

Energy-saving design reduces costs: Using technologies like variable frequency fans, dynamic air replenishment, etc., the annual power consumption of a single Stocker, and the annual nitrogen consumption of N2 Purge Stocker will be reduced.

 

 

 

Four core advantages: GETECH Stocker builds a moat with technology and service

 

 

 

As the enterprise with 'earliest R&D and most shipments' in the domestic Stocker field, GETECH relies on four advantages: technology, product, delivery, and system, building an industry moat that is difficult to replicate.

 

1. Technology leading, breaking the monopoly of high-end storage equipment

 

As an industrial intelligent solutions provider strategically incubated by TCL, GETECH established a new subsidiary—Wilson Optimus(Shanghai) Intelligent Technology Co.,Ltd. through strategic acquisition in 2024, building a complete AMHS product system, and domestically first produced and delivered Tower Stocker and N2 Purge Stocker, filling the technical gap in domestic high-end storage equipment. In the future, GETECH will continue to optimize Stocker's technical parameters, such as improving handling efficiency, positioning accuracy, and safety redundancy, to meet the needs of semiconductor production lines for scaling and automation upgrade.

 

2. Full-scenario equipment matrix, covering the entire semiconductor process intelligent storage

 

To cover the entire semiconductor process storage needs, GETECH provides wafer box storage equipment (Normal Stocker), tower cross-floor storage equipment (Tower Stocker), reticle box storage equipment (Reticle Stocker), nitrogen filling storage equipment (N2 Purge Stocker), as well as supporting equipment like overhead buffer unit (OHB), buffer storage equipment (NTB). At the same time, optional configurations like manual port/overhead crane port/AGV port/Auto Teaching, etc., through refined software and hardware module combinations and dedicated configuration tools, quickly respond to customer customized storage needs.

 

3. Rapid delivery + 7*24 service, ensuring production line quick implementation and stable operation

 

With deep semiconductor industry Know-How, strong supply chain support, professional project delivery team and installation construction team, GETECH Stocker can achieve equipment delivery in as fast as 2.5 months, complete installation and commissioning delivery within 3 months, shortening by more than 50% compared to international brands (average 6-8 months). At the same time, establishing an all-weather service mechanism, responding to customer feedback issues within 2 hours at the fastest, and arriving on-site for maintenance within 4 hours.

 

4. Deep integration of CIM+AMHS, driving whole factory full automation

 

Different from single equipment suppliers, GETECH provides an 'AI+CIM+AMHS' overall solution, one-stop providing material automation upstream and downstream systems, including MES, RTS, MCS, RTD, OHT, Stocker, etc., avoiding multi-vendor equipment interface incompatibility and data smoothness issues; at the same time, through software-hardware integration and whole factory control, achieving full-link data breakthrough, helping factories achieve unmanned and efficient operation.
