Indium Corporation Expert to Present at Wafer-Level Packaging Symposium

Indium Corporation’s innovative materials for advanced semiconductor packaging will be the focus of a presentation by Dr. Dongkai Shangguan, strategic advisor, at the Surface Mount Technology Association’s Wafer-Level Packaging Symposium, Feb. 15-17, San Jose, Calif., U.S.

As advanced packaging continues to drive towards heterogeneous integration, new materials need to be developed to address the many challenges faced in the assembly process. In his presentation Innovative Materials for Advanced Semiconductor Packaging, Dr. Shangguan will cover cutting-edge materials for this technology, including novel flux formulations and adhesive agents for wafer/die bonding, interactions between the flux material and various dielectric materials on the wafer, and materials for thermal management in high density packaging. The presentation will introduce the different processes and the associated materials, and the benefits and disadvantages of the various options will be discussed in detail. Proper selection and application of interconnect materials for the various assembly processes is crucial to ensuring a high production yield during the assembly process for reliable wafer-level packages.
