What HYS COM does

HYS COM (Hon Young Semiconductor Co., Ltd.) is a Taiwan-based pure-play wafer foundry specializing in silicon carbide (SiC) and silicon power semiconductors. Established in 2021 and headquartered in Hsinchu Science Park, the company operates as a majority-owned subsidiary of Hon Hai (Foxconn) Technology Group, which holds approximately 98.9% equity. It serves the electric vehicle, green energy, industrial, and consumer electronics end-markets through a vertically integrated foundry model spanning TCAD simulation, epitaxy, wafer fabrication, packaging, and final test, including multi-project wafer (MPW) prototyping services for fabless customers.

The company's technical platform is built around a 6-inch SiC and silicon wafer fabrication line acquired from Macronix (Winbond) in August 2021. It achieved first SiC MOSFET production capability at 1200V in September-October 2022 and offers a stated voltage range of 650V to 3300V. The company holds a comprehensive set of quality and compliance certifications — ISO-9001, IATF-16949 (automotive), ISO-14001, ISO-45001, ISO-37301, ISO-14064-1, IECQ-QC080000, and CNS-45001 — positioning it to qualify for EV traction inverter, on-board charger, and industrial drive supply chains. Management is led by Chairman David Huang and CEO Bob Chen.

Revenue mechanics are foundry-based — priced per wafer and per packaged unit — rather than direct chip sales. The company is at an early-commercial stage: it is in a first-phase hiring ramp of 200+ employees at Hsinchu, its parent Foxconn has taken a 10% equity stake in SiC substrate supplier Shengxin Materials to secure upstream supply, and a planned upgrade to an 8-inch fab targeting 200,000 wafers/year capacity is scheduled for 2025. Customer demand is expected to be anchored by Foxconn's MIH EV platform and in-house power electronics programs, supplemented by external fabless SiC customers served through MPW and TCAD design services.

Core offering

Hon Young Semiconductor (HYS) is a pure-play power semiconductor wafer foundry providing 6-inch Silicon Carbide (SiC) and silicon wafer manufacturing services for electric vehicle and green energy applications. The company operates a SiC process platform spanning 650V to 3300V for SBDs and Power MOSFETs, a silicon platform covering CMOS, HV, BCD, UHV, Metal Gate, and BJT, and turn-key services including epitaxy, implant, annealing, metallization, chip probing, packaging, and final test.

Product overview

Hon Young Semiconductor (HYS) operates as a pure-play wafer foundry providing two primary manufacturing platforms: Silicon Carbide (SiC) and Silicon wafer process platforms. The SiC platform offers 6-inch wafer manufacturing for MOSFETs and Schottky Barrier Diodes (SBDs) spanning 650V to 3300V applications, while the Silicon platform provides CMOS, HV, BCD, UHV, Metal Gate, and BJT process technologies for controller ICs, driver ICs, and power management ICs. These platforms are supported by turn-key solution services including process/electrical simulation (TCAD), MPW development, and full turn-key services from epitaxy through packaging and final test.

Others

• Shengxin Materials Technology: China-based SiC substrate manufacturer in which Foxconn holds a 10% equity stake to secure SiC substrate supply for HYS. Relevant as an upstream ecosystem partner rather than a competitor; HYS relies on Shengxin for the most supply-constrained input in its value chain.

Direct peers

• Episil Technologies: Taiwan-based pure-play compound semiconductor (SiC, GaN) and silicon epitaxial wafer foundry. Directly comparable to HYS as a Taiwan-based foundry serving automotive and industrial power semiconductor customers with SiC epitaxy and wafer processing services.
• Vanguard International Semiconductor (VIS): Taiwan-based specialty IC foundry offering CMOS, HV, BCD, and power semiconductor processes. Closely comparable to HYS's silicon-based HV/BCD/UHV platform; Chairman David Huang was previously VIS CFO, indicating direct operational lineage.
• X-FAB Silicon Foundries: Global pure-play analog/mixed-signal foundry offering HV, BCD, and SOI processes including SiC foundry services. Comparable as an independent foundry serving automotive and industrial power customers with specialty process platforms.

Broad incumbents

• Wolfspeed: US-headquartered pure-play SiC powerhouse spanning substrate, epitaxy, and device fabrication. The dominant incumbent in SiC power semiconductors that HYS competes against; broader portfolio and at-scale 8-inch Mohawk Valley fab set the benchmark HYS is racing toward.
• ON Semiconductor (onsemi): US-based power semiconductor IDM expanding aggressively into SiC through the GT Advanced Technologies acquisition. Competes with HYS for EV traction inverter and DC-DC converter design wins across automotive OEMs.
• STMicroelectronics: Global IDM with a major SiC MOSFET and power module franchise through the STMicroelectronics-Tesla-Wolfspeed axis and its own Catania SiC fab. Competes with HYS for automotive EV power inverter sockets as a vertically integrated incumbent.
• ROHM Semiconductor: Japanese IDM with vertically integrated SiC substrate-to-module manufacturing and a long-term SiC supply agreement with Vitesco (now part of Schaeffler). Comparable as a SiC power device competitor serving automotive Tier-1 customers globally.
• Tower Semiconductor: Israel-based specialty foundry offering RF, analog, HV, and power process platforms. Comparable as a pure-play specialty foundry serving industrial and automotive power semiconductor customers, though it does not focus on SiC specifically.
• Coherent Corp (formerly II-VI): US-based materials and compound semiconductor company vertically integrated in SiC substrates and devices. Competes with HYS's foundry offering while also constraining substrate supply via its own wafer production; a structural counterpart across the SiC value chain.
