Hsinchu: ASE Technology Holding Corp.'s subsidiary, Siliconware Precision Industries Co. (SPIL), has acquired factory buildings and equipment from United Renewable Energy Co. for approximately NT$2.8 billion (US$88.44 million).

According to Focus Taiwan, ASE Technology, the leading global provider of IC packaging and testing services, did not specify the intended use of the newly acquired property at Hsinchu Science Park's Miaoli section, mentioning only that it would support future operations. Industrial sources speculate that SPIL intends to utilize the space to enhance its advanced IC assembly capacity in response to increasing demand amid the AI boom.

The facility spans five levels above ground and three levels below, covering a total area of 41,030.55 square meters. Real estate agents noted that the factory was highly sought after by various IC packaging and testing service providers, but SPIL ultimately secured the property. United Renewable Energy reported a profit of NT$2.1 billion from the sale.

According to industrial sources, ASE Technology anticipates an order backlog for AI-related advanced 3D chip on wafer on substrate (CoWoS) IC assembly services. To further expand its capabilities, SPIL announced plans over the weekend to construct five additional factory buildings in its Changhua compound, expected to be operational by 2027.

SPIL has been actively increasing its capacity over the past year. In April 2025, the company secured surface rights for 20 years to a parcel of land in the Central Taiwan Science Park's Houli section in Taichung to build new facilities for advanced IC assembly and testing. Additionally, in January 2025, SPIL opened a new plant in the Taichung Tanzi Technology Industrial Park, with Nvidia Corp. founder and CEO Jensen Huang attending the ceremony, aiming to secure more CoWoS capacity.

ASE Technology reported consolidated sales of NT$645.39 billion in 2025, marking an 8.4 percent increase from the previous year.
