Initiation of the mass production of HRDP®, a special glass carrier for next-generation Semiconductor packaging devices.

Beginning mass production and shipment for a multi-chip module manufacturer in January 2021

For the commercialization of HRDP®1, a special glass carrier for the next-generation semiconductor packaging devices, Mitsui Mining & Smelting Co., Ltd. (President: Keiji Nishida; hereinafter, “Mitsui Kinzoku”) has been expanding the establishment of a system for mass production in collaboration with GEOMATEC (President: Kentaro Matsuzaki). Mitsui Kinzoku is pleased to announce that mass production of HRDP® has started for a domestic multi-chip module manufacturer.

In its January 2018 news release, Mitsui Kinzoku announced the development of HRDP®, a material for the creation of ultra-fine circuits using a glass carrier for the Fan Out panel level package, based on the RDL First method2

HRDP® is a special glass carrier capable of achieving high production efficiency of the Fan Out packages3 , the next-generation semiconductor packaging technologies, including ultra-high density circuits designed with a line/space (L/S) ratio of 2/2 um or less4 . Currently, over 20 customers are evaluating HRDP® for commercialization.

As the first stage, mass production for a domestic multi-chip module manufacturer began in January 2021. This customer will use HRDP® to manufacture devices for the 5G market, which is expected to expand in the future, including RF modules5 , and other devices for a variety of applications with plans to increase sales.

As the second stage, an overseas package manufacturer is planning to adopt HRDP® within FY2021.

In addition, there are plans to initiate the mass production at the other new customers for a variety of applications, such as HPC6 and mobile phones for FY2022 and onward, and the HRDP® market is expected to expand.

Under its slogan of Material Intelligence, Mitsui Kinzoku will realize customers’ wishes to ensure stable quality and sufficient supply, to provide customers with one stop solutions and to endeavor to increase its market share
