Sustainable Operation
Business Philosophy
In 1986, President Mr. Chiao Ping Hai established Helitek Corporation in USA and started up business of silicon wafer which was the predecessor of Wafer Works Corporation. Also, it laid the foundations of silicon wafer development for Wafer Works Corporation. In 1997, Wafer Works Corporation was established in Taiwan; through steady development of its core business, we expand production base to six plants across the Taiwan Strait.  The company has become the top 6th supplier of semicon materials in the world. In the meantime, it is the second largest manufacturer of heavily doped low-impedance products.
Wafer Works plants aim to fulfill customer satisfaction and long-term goal since the beginning; this concept has become the core value of the company - customer-oriented.
Besides constant advancement of technologies and development of high-quality silicon wafers, Wafer Works Corporation stands in the view of customers to provide best solutions to conform to market trends and customer demands so as to become a reliable supplier of semicon materials.
Wafer Works Corporation is convinced that success only lies in building mutual-trust and cooperative partnership between customers and suppliers, comprehensive understanding of customer demands, closely working with suppliers, and jointly development of innovative products and services beyond customer expectations. Externally, Wafer Works Corporation is compliant with customers and loyal to the commitments to customers. The company is run based on the philosophy of integrity, co-creation, and sharing to achieve triple-win situation with company, customers, and suppliers. In the meantime, employees are the core value of the company; we recruit and retain outstanding talents with the core values of the company, and promise to create a safe and inclusive workplace to ensure that each employee enjoys a friendly working environment with human rights, skills development and safety.
Outcomes have been shared with staff. Wafer Works Corporation regards sustainable development as the highest principle and strides towards the goal of "A customer-oriented supplier of semicon materials". Meanwhile, we keep bringing positive influence to the society through the five major aspects to implement corporate social responsibility, namely corporate governance, employee care, environmental sustainability, customer service, and social participation.
