Huawei Develops 14nm EDA Tools for Mass Production of Kirin 9020, Yet Still Restricted to 7nm Architecture

Electronic Design Automation (EDA) tools play a pivotal role in the semiconductor manufacturing sector, even though they do not directly contribute to the production of chips. These sophisticated tools are indispensable for the design and validation processes, ensuring that fabrication meets specific performance requirements. For companies like Xiaomi, the absence of these advanced tools presents a significant barrier in advancing technology beyond the 3nm threshold while developing innovations such as the XRING 02. TSMC’s latest 2nm technology, utilizing a GAAFET (Gate-All-Around Field-Effect Transistor) structure, highlights the necessity of intricate EDA systems—especially as restrictions on exports have been implemented by the Trump administration. In an intriguing turn of events, reports indicate that Huawei has found ways to navigate these restrictions and has made strides in creating its own EDA solutions.

Huawei’s Journey Towards Semiconductor Independence

According to a comprehensive report from DigiTimes, Huawei is actively collaborating with various Chinese EDA firms to develop their own alternatives, thus eliminating dependence on foreign entities. Notably, in March 2023, Huawei reportedly gained full control over 14nm EDA solutions, intending to leverage these tools for the production of the Kirin 9020 chipset. Launched alongside the Mate 70 flagship series, this chipset is anticipated to also power the upcoming Pura 80 lineup.

Despite these advancements, Huawei faces a formidable challenge in acquiring next-generation Extreme Ultraviolet (EUV) machines essential for producing wafers at the 5nm process node and below, without encountering yield problems. Currently, Huawei depends on SMIC’s Deep Ultraviolet (DUV) equipment to manufacture the Kirin 9020 using a 7nm process. Reports suggest that its partner, SiCarrier, is exploring EUV alternatives that could rival ASML’s technology. Although SiCarrier has undertaken significant funding efforts, raised at $2.8 billion to support these ambitions, it may still take several years before Huawei can achieve full autonomy in this crucial area.

The future landscape may see more Chinese companies adopting similar EDA tools. For Xiaomi, which aims to compete fiercely with industry giants like Qualcomm, MediaTek, and Apple, reliance on older lithography systems is not a feasible strategy. This situation could potentially pave the way for a collaboration between Huawei and Xiaomi as they work together to innovate and develop advanced EDA tools. However, this strategic partnership remains a topic for future discussions.
