UMC Business Continuity Management System Development and History

UMC recognizes the issue of business continuity, which means the importance of providing continuous services to strategic customers and stakeholders. UMC has developed and established site level BCP (Business Continuity Plan) in each fab since 1999,and became a leader in the industry in 2013 when the headquarter in Hsinchu and Fab12A_1 in Tainan were the first to pass ISO 22301 Business Continuity Management system verification, thereafter the verified scope was progressively expanded to Fab12i in Singapore and Fab12A_2 in Tainan. The BCMs verification will be promoted to other UMC sites in the future according to the pre-approved objective schedule.



UMC Business Continuity Policy and Objective

UMC strives to provide the most competitive wafer foundry services and pursuing the business continuity of enterprise, strategic customers and stakeholders, and to fulfill risk management mechanism to ensure continuous service. Our business continuity policy and objectives are:

  • UMC aims to provide customers with more excellent and continuous service.
  • UMC carries out business continuity system operation and resources integration to ensure the system’s effectiveness.
  • UMC reviews and improves continuously to enhance the resilience of responding to various disasters before/ during/ after the disruption from business impact to ensure the utmost rights and interests of customers and stakeholders.


  • Personnel safety is the top business continuity objective.
  • UMC achieves its business continuity objective by reducing operational impact and shortening recovery time through thorough risk assessment and the establishment of preparedness as well as response capabilities to various disasters.
  • UMC follows ISO 22301 management system standard and executes BCP drill on a regular basis to review the effectiveness of business continuity plan and make continuous improvements.



BCM Framework

UMC follows the ISO22301 standard to establish, implement, monitor and maintain BCMs, with continual improvement of the system, to ensure that business operations continue during incidents or disasters, and to realize the goal of non-interrupted operation.

All UMC fabs and functional departments have deployed emergency response and recovery plans for specific events such as earthquake, fire, chemical spill, power disruption, water shortage and material shortage. BCP Exercise are conducted every year in order to continually improve emergency response and recovery procedures.





Stage 1. Incident management

Stabilize the effect of incidents or disasters as per the emergency response plan.



Stage 2. Business continuity

Achieve minimum operational goals within the recovery time objective, RTO, as per the business continuity plan.



Stage 3. Business recovery

Recovery at the affected fab to restore its production capability back to normal within maximum acceptable downtime as per business recovery plan.



Operation of Business Continuity Management

In 2013, UMC, a leading global semiconductor foundry, received ISO 22301 certification for its business continuity management system and became the first foundry worldwide to achieve ISO 22301 certification. In 2016, certification was extended to UMC’s Fab 12i in Singapore to compelte the company goal of certifying all of its 12-inch fabs, reaffirming to customers UMC’s commitment to providing uninterrupted foundry services.


To this day, UMC continues to maintain and review the effectiveness of our BCM system by third party* every year to ensure that when disasters occur, UMC can maintain the minimum operating level and continue to recover, thus protecting the best interests of customers and stakeholders.


In addition to yearly BCP exercises using different scenario, we also conduct an MT level drill once every 3 years. The drill is convened by President Chien and related executive members including CFO, CHO, the 12-inch manufacturing vice president, manufacturing resource integration vice president, etc. We practice stakeholder’s communication tactics in various aspects, including employees, suppliers, customers, investment banks and social media. In addition, production allocation plans between different fabs are also adopted. It demonstrates UMC’s resilience in business continuity.


* The third party audit and revisit was executed by BSI (British Standard Institution).
