According to the news from Money UDN, amid a tough semiconductor market, once-stable long-term contracts for silicon wafer makers have turned uncertain. A major Taiwanese foundry seeks price cuts in upcoming contracts from a Japanese supplier. Intense negotiations are ongoing, potentially affecting industry dynamics and pricing strategies due to the Japanese suppliers’ pivotal role in the supply chain.

Market insiders suggest silicon wafer makers may resist price reductions due to their vital role in foundries. Reports hint at foundries’ challenges and the ripple effects on critical materials suppliers.

Globally, Japan’s Shin-Etsu and SUMCO are top silicon wafer suppliers, trailed by Taiwan’s GlobalWafers, Germany’s Siltronic, and South Korea’s SK Siltron. And Taiwan SUMCO joint venture with Formosa Plastics Group as “Formosa Sumco Technology”, and other companies like Wafer Works. With over 30% market share, Shin-Etsu leads, closely followed by SUMCO, combining for around 55% to 60% global share.

Taiwan’s foundries include TSMC, UMC, VIS, and PSMC, among others. TSMC, with a global market share exceeding 50%, holds a leading position in the industry.

Silicon wafers are essential raw materials for semiconductor foundries, integrated device manufacturers (IDMs), and memory manufacturers. Presently, the standard duration for silicon wafer long-term contracts ranges from three to 8 years, specifying annual supply and demand quantities. In the previous semiconductor boom, these long-term contracts often featured escalating prices year by year.

Semiconductor market shifts led to reduced foundry capacity use, heightening tensions with silicon wafer makers’ clients. Delays emerged in the last quarter, leading to agreements between manufacturers and clients. This trend has persisted into the first half of this year. Silicon wafer industry insiders acknowledge slow end-market demand recovery and relatively high client inventories.

Amidst this situation of overflowing inventories, reports indicate that a major Taiwanese silicon wafer foundry is requesting Japanese silicon wafer suppliers to not only agree to further delays in this year’s contracted shipments but also to lower prices for next year. However, no formal agreement has been reached by the silicon wafer manufacturers at this stage.

A juridical person suggests that the negotiations are currently at a deadlock, and the situation might become clearer in the fourth quarter. If the silicon wafer manufacturers eventually concede, they are unlikely to publicly admit it, in order to prevent other clients from seeking similar adjustments and causing wider disruptions.

Market insiders also reveal that the Japanese silicon wafer manufacturers facing price reduction demands are currently operating relatively well and are adopting a firm stance. From the perspective of the foundries, they are hoping for support from their supply chain partners to alleviate the pressure. Normal silicon wafer inventories typically span two to three months, yet certain silicon wafer foundries are already grappling with high inventory levels, particularly for 8-inch wafers, which might persist throughout this year.

A powerful magnitude 7.3 earthquake occurred off the coast of Fukushima, Japan on the evening of March 16th (CST). Most of northeastern Japan is a production center for global upstream semiconductor raw materials. According to TrendForce investigations, in the main quake zone, only Kioxia’s K1 Fab (located in Kitakami) will face the possibility of a further downgrade to 1Q22 production. Some of the remaining memory or semiconductor companies in the region are conducting machine inspections but the overall impact has been muted.

In terms of memory, the intensity of the earthquake at Kioxia’s K1 Fab reached magnitude 5. When the earthquake occurred, wafer input was partially damaged. At present, K1 Fab has been shut down for inspection. The 1Q22 production capacity of the K1 Fab had been downgraded following the recent contamination incident and accounts for approximately 8% of Kioxia’s 2022 production capacity. Operating under a cloud of possible aftershocks, Kioxia’s capacity utilization rate may be slow to recover in the next week, causing further downward revision of K1 Fab’s 1Q22 production. The remaining Kioxia factories are unaffected, as is Micron’s Hiroshima plant.

Looking at the market spot price, pricing has moved up since February due to the contamination of Kioxia’s raw materials. The Russian-Ukrainian war did not trigger significant upward or downward movements in spot price. After last night’s Fukushima earthquake, pricing remains stable. TrendForce asserts, overall spot demand remains weak and prices are not prone to drastic changes.

In terms of raw wafers, SUMCO’s Yonezawa Plant in Yamagata and Shin-Etsu’s Shirakawa Plant in Fukushima are both within the affected area, experiencing an earthquake intensity of magnitude 5. Due to the extremely high stability required in the crystal growth process, the industry has not yet announced the impact of the quake. TrendForce specifies, in addition to shutdown inspections, damage to machines and silicon wafer input is inevitable. However, in addition to redistributing production plans, buildings were reinforced after the 2011 Tohoku earthquake and tsunami in Japan, so overall damage may be minor.

In terms of foundries, there are two 12-inch wafer fabs and two 8-inch wafer fabs in Japan, including UMC Fab12M (12-inch), Tower Uozu (12-inch), Tonami (8-inch), Arai (8 inches), located in Mie, Toyama, and Niigata prefectures, respectively, and separately experiencing quake magnitudes from 1 to 3. At present, these fabs are operating normally and any impact of the quake on the plants are largely insignificant. However, IDM manufacturer Renesas’ Naka plant is within the magnitude 5 zone and they have also shut down and reduced production to confirm the impact of the quake.
