DuPont Wafer Level Packaging Solutions, Nippon Kayaku and MicroChem Sign Joint Development Agreement
3D and TSV Semiconductor Packaging Designs Drive Demand for New Photodefinable Epoxy Based Materials
Mr. Hirotsugu Tsubouchi
DuPont Wafer Level Packaging (WLP) Solutions (http://wlpsolutions.dupont.com), part of DuPont Electronic Technologies, and Nippon Kayaku Co. Ltd. (NKC), together with NKC’s wholly owned subsidiary, MicroChem Corp. have signed a Joint Development Agreement to develop new advanced photodefinable epoxy based materials directed to emerging WLP and 3D/Through-Silicon Via (TSV) applications. DuPont WLP Solutions and MicroChem have developed a first generation photodielectric adhesive dry film material that will soon be commercialized as DuPont™ PerMX™ 3000. With new advanced epoxy resins from Nippon Kayaku, the largest supplier of epoxy resins for microelectronic applications, the companies expect to accelerate product development and introduce a series of new materials over the next five years.
DuPont estimates the materials market for wafer level packaging, 3D and TSV to grow from about $100 million in 2009, to more than $600 million in 2013, and could as much as double to $1.2 billion by 2015.
"Combining the expertise of Nippon Kayaku and MicroChem in advanced epoxy resins and formulation, with DuPont coating technology, material science and electronic applications knowledge means that we can generate a series of enabling materials faster," said Mats J. Ehlin, global business manager -- DuPont Wafer Level Packaging Solutions. "We’re excited about this opportunity to further expand our offering and strengthen our ability to help customers meet their needs for improved performance, form factor and reduced cost."
Applications for the DuPont™ PerMX™ photodielectric adhesive dry film series include CMOS image sensor packaging and wafer level camera modules, wafer level cavity packages for electronic components, MEMS devices and LED displays, bonding for 3D packaging, and various dielectric layers for new advanced wafer level chip scale packages (WLCSP).
"Nippon Kayaku Co. is widely acknowledged for its experience in epoxy resin and formulation for semiconductor packaging," said Masaru Oizumi, general manager -- Electronic Materials Division, Nippon Kayaku Co., Ltd. "This joint development requires new high performance epoxy resins and formulations, and I believe our experience will contribute to expand new business opportunities, including the development of MEMS resists. MicroChem also will support and accelerate our new product developments."
3D/TSV packaging technology is emerging as a leading solution to extend Moore’s law by significantly improving performance, further reducing form factors, and eventually providing even more cost effective methods for the packaging of semiconductor devices such as advanced memory, logic and SiP (System in Package).
Wafer level packaging is spreading rapidly as a way to significantly improve the efficiency and reduce the size of semiconductor packages. Rather than package and test single components, the packaging process takes place on the semiconductor wafer before each semiconductor chip is singulated. For example, DuPont™ PerMX™ photodielectric adhesive dry films can enable wafer level packaging of new CMOS cameras or radio frequency components by creating a protective cavity around each chip in a single process involving thousands of components on a wafer. Glass or a second layer of DuPont™ PerMX™ photodielectric adhesive dry film can be bonded on top, without any additional need for adhesives, prior to singulation of each component.
