Title: Ang Yu Xin Kristy: Innovator in Wafer Level Packaging Processes
Introduction
Ang Yu Xin Kristy is a prominent inventor based in Singapore, known for her contributions to the field of wafer level packaging processes. With a focus on innovative methods and apparatus, she has made significant strides in addressing challenges related to warpage in substrate materials.
Latest Patents
Kristy holds a patent titled "Methods and apparatus for controlling warpage in wafer level packaging processes." This invention outlines techniques for producing fine pitch patterning on a substrate. The process involves warpage correction of the substrate, which can be accomplished on a carrier or carrier-less substrate. A first warpage correction process is performed by raising and holding the substrate's temperature to a first temperature and cooling the carrier-less substrate to a second temperature. Following this, further wafer level packaging processing is conducted, such as forming vias in a polymer layer on the substrate. A second warpage correction process is then executed, raising and holding the substrate's temperature to a third temperature and cooling it to a fourth temperature. With the warpage of the substrate reduced, a redistribution layer can be formed on the substrate with a 2/2 μm l/s fine pitch patterning.
