The new chip plant in Kumamoto, Japan, operated by Japan Advanced Semiconductor Manufacturing (JASM), a joint venture between Taiwan Semiconductor Manufacturing Co. (TSMC), Sony, and Denso, is poised for substantial capacity growth.

JASM President Yuichi Horita revealed that after commencing production in the fourth quarter of 2024, the plant’s production capacity will gradually ramp up, targeting a full capacity of 55,000 12-inch wafers per month.

Simultaneously, TSMC aims to enhance Japan’s semiconductor supply chain and ecosystem, looking to a 60% local contribution by 2030, a significant increase from the current 25%.

Yuichi Horita unveiled the latest plan for TSMC’s Kumamoto plant during his speech at the SEMICON Japan. He emphasized that TSMC’s Kumamoto plant is actively working to establish a local supply chain and ecosystem in Japan.

The current proportion of equipment and materials sourced from Japan for the Kumamoto plant is approximately 25%. The goal is to increase this to 50% by 2026 and achieve 60% by 2030. The progress in constructing production capacity, trial production, and mass production is in line with the original plan.

Yuichi Horita stated that the current workforce at the Kumamoto facility stands at 1,700 employees. Among them, around 600 are dispatched by TSMC and Sony, with the remaining being newly recruited staff.

The production capacity of the new Kumamoto plant primarily focuses on 28/22 nanometers and 16/12 nanometers. In the initial phase, the majority of the capacity is allocated to the manufacturing of Image Signal Processor (ISP) used in CMOS image sensors, as part of Sony’s outsourcing.

The remaining capacity is dedicated to automotive parts supplier Denso, where they outsource the production of automotive microcontroller unit (MCU), with Denso reportedly able to obtain approximately 10,000 wafers per month.

Reportedly, in industry analysis, although Japan’s recent performance in foundry has not matched that of Taiwan, South Korea, and China, Japan’s semiconductor equipment supply chain is already quite mature and comprehensive.

Major players in the field, such as Nikon in lithography equipment, and Hitachi High-Tech, renowned for etching equipment and critical dimension scanning electron microscopy (CD-SEM), have established dominance.

Additionally, Japanese companies specializing in chemical solutions, gases, and materials have also secured significant positions. All of these factors make them crucial partners for supporting the development of TSMC’s Kumamoto plant in the future.

Industry source suggests that in the future, the Japanese government will not only continue to subsidize semiconductor manufacturing but also strengthen collaboration between the semiconductor industry and academia to attract more talent into the semiconductor industry.

According to a report by Taiwan’s Commercial Times, China’s Haitong Securities has taken the lead in reducing shipment expectations before Apple’s upcoming new product launch next month. The company has lowered the shipment forecast from the initial 83 million units to 77 million units, marking a decrease of 6 million units.

Industry experts point out that lackluster demand in the end market and challenges in the manufacturing process are the main reasons behind the market’s growing skepticism towards iPhone 15 shipment numbers.

Haitong Securities indicates that Apple’s iPhone 15 shipment volume could be revised down to 77 million units. This is primarily due to lower-than-expected yield rates for the CMOS image sensors (CIS) provided by Sony for the periscope lenses. The production bottleneck for iPhone 15 and Plus models is Sony’s 3-layer CIS structure (PD/TX + pixel + ISP), leading to subpar production yields.

Industry experts also mention that the high difficulty in producing the titanium metal frame is attributed to the differing coefficients of thermal expansion between titanium and aluminum. However, this issue can be managed by increasing Foxconn’s production capacity.

The LIPO (Low Injection Pressure Overmolding) screen, on the other hand, faces low yield rates from LG and will need Samsung’s support. Nonetheless, the supply situation for these two components should reach a controlled stage.

Industry sources believe that delays in production for iPhone 15 stem from Sony’s lens sensors, the new titanium alloy frame, and the 1.55mm narrow border screen. However, the primary reason for Apple’s adjustment of iPhone 15’s sales target remains concerns over demand. Both the iPhone 15 Pro and iPhone 15 Pro Max are expected to come with higher price tags, potentially dampening consumer willingness to purchase. The decision to trim production plans prior to the new phone’s release warrants close attention to whether it garners consumer acceptance after hitting the market.

Sony, a major supplier of Apple’s camera sensors, suggests weaker demand for the upcoming iPhone 15 due to a lackluster year for Apple’s iPhone sales. Economic challenges have affected iPhone sales, though service revenues have offset losses. The flagship iPhone 15 series is scheduled for a September release.

Sony the world’s largest sensor supplier, had previously projected a gradual recovery in its smartphone imaging and sensing business by the second half of 2023. However, during its latest earnings call, the company revealed that this recovery might not take shape until 2024, mainly attributing the delay to underwhelming sales in the Chinese market.

Sadahiko Hayakawa, Sony’s Senior General Manager of Finance, stated, “The recovery pace of the Chinese smartphone market has been slower than our expectations, and the situation in the US market is worsening. We originally anticipated the smartphone market to recover starting from the second half of this fiscal year, but our current assessment suggests that it might not happen until at least next year.”

Sony’s top brass attribute a cautious outlook to a sluggish global economy and geopolitical uncertainties, hinting at muted demand for the iPhone 15 series. This stance resonates with analyst Ming-Chi Kuo view at TFI Securities, forecasting that iPhone 15 might struggle to surpass iPhone 14 sales records, posing challenges to Apple’s suppliers in H2 2023.

Apple reported a 2.4% decline in iPhone sales for its third fiscal quarter, reaching $39.7 billion, slightly below analyst estimates of $39.9 billion. The US region saw a 5.6% year-on-year drop in sales, highlighting a performance that falls short of expectations.

As the mass production of the new iPhone draws near, TrendForce, in April this year, raised concerns in the smartphone industry about several design changes made to the 2023 iPhone models almost half a year ahead of production. The industry is closely monitoring whether related components can keep up with the production schedule to ensure smooth execution of subsequent assembly plans. Recently, TrendForce provided updates on the production progress and details of these components.

According to TrendForce’s investigation, two critical components in the iPhone supply chain are causing worries about potential supply issues – the CIS (CMOS Image Sensor) and the titanium alloy frame. Currently, there are still bottlenecks in the production of these components that need to be overcome.

Regarding the CIS, the bottleneck arises from Sony’s supply of the new 48MP CIS, which is expected to be used in iPhone 15 and iPhone 15 Plus. This CIS adopts a new stacked design, separating the CIS photodiodes and peripheral transistors into three layers instead of the previous double-layer structure. This poses a significant challenge to yield rates, and despite Sony’s efforts to increase production capacity to cope with the yield ramp-up difficulties, the supply situation does not meet anticipated levels, affecting the initial production schedule of the entire device.

As for the titanium frame, due to the elimination of the pressure-sensitive button structure and the slight adjustment in the opening for the mute switch, the suppliers need to re-allocate, set up, and verify the basic operating time of the production lines.

Additionally, the processing procedures for titanium are more complicated compared to stainless steel, which leads to longer production lead times. TrendForce confirmed recently that the titanium frame for the new iPhone is currently one of the components with lower yield rates and supply stability. Therefore, suppliers have expanded production capacity by 20-30% and are working diligently to ensure that even if the initial supply is tight during the early stages of production, they can respond accordingly, ensuring that the launch and supply of the entire device will not be affected.

Given the supply constraints of these two components mentioned above, TrendForce believes that Apple may increase the production proportion of the two Pro models in 3Q23 to fill the gap caused by the initial iPhone 15’s production capacity shortage. This adjustment, in an optimistic scenario, will only involve shifting production proportions between different models in two quarters, with no impact on the annual shipment performance. TrendForce assesses that this possibility is more likely under the current circumstances.

However, if the CIS yield bottleneck is difficult to overcome, it could lead to a substantial reduction in the shipment volume of the 2023 iPhone models. TrendForce will continue to monitor the situation closely.

With the release of Apple’s Vision Pro, its Micro OLED display technology has caught the attention of more people. In fact, global Micro OLED display manufacturers have been working in this field for many years. In recent years, Chinese manufacturers have been particularly active in this area.
