Company News

In the precision workshops of wafer fabs and advanced packaging and testing bases, the flow of each silicon wafer, the parameters of each yellow light exposure, and the subtle changes in each etching process are transmitting the 'voice of the process' in real-time. Gotion SPC (Statistical Process Control System) uses data as ears to accurately capture these hidden signals, transforming them into actionable insights through statistical analysis, delivering quantified value in yield improvement, cost reduction, and customer trust for over 50 semiconductor companies.

PDCA Full Process Closed Loop: Quality Control Logic from Data to Decision

Statistical Process Control (SPC) is a quality method that monitors and manages the production process through statistical techniques. Its core wisdom lies in upgrading the passive mode of 'post-inspection' to the active control of 'process prevention', by monitoring quality characteristic data in real-time during production, distinguishing normal fluctuations from abnormal variations, issuing warnings before defects occur, achieving 'prevention before problems'.

Semiconductor manufacturing, with its ultra-precision, high complexity, and multi-process联动 characteristics, imposes extreme requirements on quality control. Gotion SPC deeply aligns with industry characteristics, building a complete PDCA cycle: 'data collection → monitoring analysis → warning linkage →异常处理 → continuous improvement':

Downward integration with machine sensors, measurement equipment, factory systems, etc., for real-time data, achieving full-factor quality data access;

Upward linkage with MES (Manufacturing Execution System), EAP (Equipment Automation System), QMS (Quality Management System), forming a closed loop for异常处理;

Making every process parameter a traceable, analyzable, optimizable quality basis.

Six Core Advantages: Building Semiconductor-Level Quality Control Barriers

Gotion, deeply engaged in the SPC field, stands out in the market with six core advantages:

01 Data Access 'No Blind Spots', Full-Chain Quality Coverage

02 System Settings 'User-Friendly', Adapting to Dynamic Production Line Needs

Supports batch configuration of specification standards and control rules, built-in intelligent algorithms for automatic control limit updates, dynamically adapting to production line capability changes; highly integrated with MES, automatically triggering machine/batch Hold mechanisms when异常 occur, preventing defect spread, while supporting modular dictionary configuration, flexibly responding to personalized control needs of different factories.

03 Control Indicators 'Full Coverage', Multi-Dimensional Analysis Supporting Decisions

Covers various计量 and计数型 Charts (control charts) like Xbar/S/R/X/MR/P/NP/C/U; real-time calculation of process capability indicators such as CA/Cpk/Ppk/CpmK/Abnormal Ratio, providing visual statistical analysis charts like box plots, sample comparison charts, trend charts, built-in 8 standard WECO判异 rules (supporting coefficient customization),全方位解析 process fluctuations, offering engineers立体 analysis perspectives.

04 Monitoring and Warning 'Real-Time', Zero Delay in异常 Response

EKG-style real-time monitoring dashboard直观呈现 process fluctuations, three-level intelligent alarm system for OOS (Out of Specification), OOC (Out of Control), OOW (Warning Alert), real-time推送 through multiple channels like email,企业微信,飞书 (frequency adjustable), ensuring异常 information reaches responsible persons第一时间.

05 Graphic Operations 'Efficient', Data Analysis Efficiency Improved by 80%

Supports dual-mode switching between Charts and Reports, one-click chart merging, splitting, batch viewing, and strong correlation parameter comparison; automatic overlay of historical specification lines and control lines, point information displayed instantly upon filtering,大幅缩短 engineer problem analysis time.

06 Architecture Delivery 'Zero Worries', Dual Assurance of Security and Scalability

Uses button-level permission control and factory/production line/department data isolation mechanisms to ensure data security; B/S architecture supports direct browser access, no user limit, functions flexibly expandable with seamless upgrades; backed by 50+ project implementation experiences and 15+ professional delivery team, providing localized services,响应迅速高效.
