Semiconductor Review: Specials Magazine

On the factory floor of a semiconductor plant, silence often speaks louder than sound. Robots glide in tight synchrony, wafers slip from one stage to the next, and every motion is measured to fractions of a micron. It is in this hidden world of precision and fragility that WAFTECH Sdn Bhd has made its mark. Founded in 2007 and headquartered in Penang, Malaysia, WAFTECH has steadily carved out a reputation for designing and manufacturing wafer handling equipment that meets the rigorous demands of semiconductor fabs worldwide. While the company began as a small startup focused on precision engineering, it is now a trusted partner to some of the biggest names in the industry, including Texas Instruments, Infineon Technologies, Analog Devices, NXP Semiconductors, Renesas, and STMicroelectronics. “With clients spanning across Asia, Europe, and North America, our journey from local player to global competitor is a testament to the relentless focus on quality, innovation, and customer service,” says Ye Ying, Chairwoman. At the heart of WAFTECH’s success lies its unwavering commitment to precision. Wafer handling is a delicate operation, and every transfer needs to be flawless. This demand for precision is met by WAFTECH’s core product: its automatic wafer loader systems. These systems employ cutting-edge technologies to handle wafers of varying sizes, from the more common 8-inch wafers to the larger 12-inch wafers. What sets WAFTECH apart is not just its ability to handle wafers safely but to do so at high speeds and with the utmost accuracy, ensuring that clients' production lines remain efficient and cost-effective. Engineering Excellence WAFTECH’s engineering team is the cornerstone of the company’s success. The company’s products are built on a foundation of research, development, and continuous improvement. Every piece of equipment is engineered with a single purpose: to maximize wafer handling efficiency while ensuring zero damage during transfers. The company’s Intelligent Bernoulli End Effector, which employs a non-contact method to lift wafers, is a prime example of WAFTECH’s engineering ingenuity. This system uses air flow and vacuum to pick up and place wafers, allowing for the safe handling of even the thinnest, most delicate wafers. The company’s commitment to precision is evident in its entire product line, which features advanced robotic arms for wafer transfers. These robots move with precision, employing six-axis motion to ensure smooth handling at every stage. Additionally, WAFTECH’s proprietary vision aligners provide wafer alignment, centering, and notch detection, ensuring that every wafer is in the correct position for further processing.
