ESWIN provides high-quality monocrystalline silicon polished wafers and epitaxial wafers for ICs, which are widely used in electronic communication, automobile manufacturing, artificial intelligence, consumer electronics and other fields.
In response to the demands of advanced IC micro-nano processes for silicon wafers, ESWIN selects advanced equipment and processes, in combination with the highest level of clean room design and production control, to manufacture super-flat, superior nanotopography 12-inch silicon wafers that are free of dislocations or intrinsic flaws. At present, ESWIN owns a silicon industry base in Xi'an, which is constructed in two phases, with a design production capacity of 500,000 pieces per month. Main products are monocrystalline silicon polished wafers and epitaxial wafers used in advanced processes for ICs of 28nm and below. The applicable fields include logic IC, 3D NAND & Nor Flash, DRAM, CIS, and Display Driver IC, etc.
IC packaging & testing business provides customers with integrated DDIC packaging and testing services, including wafer gold bump processing, wafer testing, grinding, cutting, packaging and final testing. In addition, ESWIN provides development of non-display driver IC related processes, such as Power IC, RF IC, etc. According to different product categories and packaging methods, ESWIN provides Thick CU. + RDL, Cu Pillar + RDL, WLCSP and other full-process package solutions.
COF Tape
COF (Chip On Film) tape is a film substrate used for COF packaging. It is a flexible circuit board that connects the display panel with driver ICs. ESWIN owns a COF tape production base for semiconductor display IC package in Hefei province, with a monthly capacity of 70 million pieces. Adopting tape-to-tape automatic production during the entire process, ESWIN provides customers with high-quality COF tape and related products through photo-resist coating, exposure, developing, etching, testing and other processes. Products are widely used in display devices, artificial intelligence, internet of vehicles, wearable devices and other fields.
Panel-Level Packaging & Testing
FOPLP (Fan Out Panel-Level Packaging) business provides customers with cost-effective system integration packaging and testing services. ESWIN integrates mature semiconductor packaging and high-precision large-panel technologies, characterized by Fan Out, high density & high bandwidth SiP (System in Package) and panel-level technology platform, thus improving the integration of semiconductor devices and shrinking the product size and improving performance. The FOPLP platform is applicable to a variety of products, including single chip package, multi-chip package, heterogeneous chip integration and SiP. It is widely used in mobile devices, 5G, IoT, AI, high-speed computing, auto field etc.
