As reported by TheElec, Samsung is considering the possibility of using molded filler (MUF) technology in the next generation of dynamic random access memory (DRAM). This move means that Samsung is exploring innovative methods to improve the performance and efficiency of its memory solutions. MUF technology, previously used by SK Hynix in the production of high bandwidth memory (HBM), offers promising prospects for Samsung’s future DRAM efforts.

MUF technology involves inserting material between semiconductors after drilling many small holes in the semiconductor layers. This process is designed to reliably connect several semiconductors arranged vertically. Recent trials of Samsung’s MR MUF process for 3D stacked memory have demonstrated improved efficiency compared to traditional methods such as thermally pressed non-conductive film (TC NCF). However, there are considerations regarding its effect on physical properties.

While Samsung considers MUF unsuitable for HBM technology due to specific requirements, it sees potential applications in 3DS registered dual inline memory modules (RDIMMs) used primarily in server environments. This decision is consistent with Samsung’s commitment to developing server DRAM memory technologies to meet the changing needs of the industry.

MUF’s success in SK Hynix’s HBM production has attracted attention in the semiconductor industry. This epoxy molding compound is said to have benefits such as preventing the sheet from warping and improving overall performance. Samsung’s desire to develop its own MUF mix in collaboration with Samsung SDI marks a strategic move to create its own solutions tailored to its requirements.

Samsung’s potential adoption of MUF technology would have significant impacts on the semiconductor market. As a leading semiconductor company in the field of storage devices, Samsung supports MUF and can promote its widespread recognition and adoption as a mainstream technology. This development has the potential to change the face of the semiconductor materials market and lead to significant transformations in the industry.
