According to a previous report from Nikkei citing sources, TSMC is rumored to be entering the fan-out panel-level packaging sector. As cited in a report from UDN, Intel and Samsung have also announced plans to invest in this area. With TSMC, the leading wafer foundry, joining the fray, the three semiconductor giants are set to compete in fan-out panel-level packaging.

TSMC stated yesterday that the company is closely monitoring the progress and development of advanced packaging technologies, including panel-level packaging technology.

Nikkei reported that in response to future AI demand trends, TSMC is collaborating with equipment and material suppliers to develop new advanced chip packaging technology. This technology uses a rectangular substrate for packaging, replacing the current traditional circular wafer, to accommodate more chipsets on a single wafer. The report further mentioned that TSMC’s research is still in its early stages and might take several years to commercialize, but it represents a significant technological shift.

Reportedly, TSMC previously considered the challenge of using rectangular substrates to be too high, requiring substantial time and effort from both the company and its suppliers, along with upgrades or replacements of many production tools and materials.

Nikkei  also mentioned that TSMC is currently experimenting with rectangular substrates measuring 515 mm in length and 510 mm in width, providing more than three times the usable area of a 12-inch wafer.

TSMC is expanding its advanced chip packaging capacity, with the expansion of the Taichung plant mainly for NVIDIA, while the Tainan plant is primarily for Amazon and its chip design partner Alchip Technologies.

TSMC’s CoWoS advanced chip packaging can combine two sets of NVIDIA Blackwell GPU chips and eight sets of high-bandwidth memory (HBM). As single chips need to accommodate more transistors and integrate more memory, the mainstream 12-inch wafer might not be sufficient for packaging advanced chips in two years.

Samsung and Intel have also recognized the aforementioned issues and are investing in next-generation advanced packaging technologies.

Samsung currently offers advanced packaging services such as I-Cube 2.5D packaging, X-Cube 3D IC packaging, and 2D FOPKG packaging. For applications requiring low-power memory integration, such as mobile phones or wearable devices, Samsung already provides platforms like fan-out panel-level packaging and fan-out wafer-level packaging.

Intel is planning to launch the industry’s first glass substrate solution for next-generation advanced packaging, with mass production scheduled between 2026 and 2030. Intel anticipates that data centers, AI, and graphics processing—markets that require larger volume packaging and higher-speed applications and workloads—will be the first to adopt this technology.

As China keeps reducing its reliance on the global semiconductor supply chain with strong support from the authority, two major smartphone manufacturers reportedly claim to have already taped out their own 4nm mobile processors. According to the reports by Liberty Times and Commercial Times, Xiaomi and Unisoc, by using foreign IP cores from ARM and IMG, have successfully taped out domestic 4nm chips.

According to the latest data from TrendForce, Xiaomi (including Xiaomi, Redmi, and Poco) has moved past last year’s high inventory issues, achieving a total production of 41.1 million units in the first quarter and ranking third globally in market share, only after Samsung and Apple. Oppo, Transsion and Vivo are the other three Chinese smartphone brands having made it to the top six regarding global shipments.

Shanghai-based fabless chip firm Unisoc, on the other hand, is specialized in areas including 2G/3G/4G/5G, Wi-Fi, Bluetooth, TV FM, satellite communications and other related technologies, according to its website.

Citing comments from Chinese tech blogger “Oneline Technology,” the reports point out that Xiaomi’s self-developed chip has made a significant leap forward, while the performance of its 4nm chip is similar to that of Huawei’s Kirin 9000s, and is expected to be seen this year. Huawei’s Kirin 9000s is reportedly manufactured by SMIC’s 7nm.

Citing another Chinese blogger, “Fixed Focus Digital,” the reports mention that Unisoc’s 4nm chip has already taped out, achieving performance levels comparable to Qualcomm’s Snapdragon 888.

Regarding the timeline for Chinese domestically produced smartphone SoCs to reach 4nm, the reports, citing industry insiders, state that it is more likely to happen in 2026. For now, MediaTek and Qualcomm still dominate Chinese’s smartphone chip market.

Apple is reportedly shifting its mixed reality (MR) device strategy by abandoning the development of its existing high-end Vision Pro headset in favor of launching an affordable MR device expected to debut next year. According to a report from Economic Daily News, it’s rumored that Foxconn is likely to replace Luxshare as the manufacturer for Apple’s affordable MR device, although Foxconn typically refrains from commenting on order specifics and client relationships.

Alongside this move, Apple reportedly plans to incorporate AI capabilities into the product, which is anticipated to significantly boost sales of the affordable MR device. Per the sources cited by the same report, they are optimistic that companies like Genius Electronic Optical (GSEO) and GIS Industries are poised to benefit from the opportunities.

According to a report from tech media outlet The Information citing sources, Apple initially planned to release two versions of the Vision device, akin to the standard and Pro versions of the iPhone. However, Apple is said to have informed at least one supplier to halt the development of the next-generation high-end Vision Pro headset.

Recently, Apple has planned to launch the USD 3,500 Vision Pro in eight new markets, including China and Japan. However, The Information, citing a source from a supplier, reported that after receiving Apple’s forecast of weakened demand for the Vision Pro by August, the supplier cut production by half in May.

The sole supplier, which has no competitors, produced approximately 460,000 Vision Pro components in the first four months of this year and plans to produce an additional 100,000 components from May to August. This suggests that Apple expects to produce at most around 500,000 units this year, with no significant production increase before August.

The Information revealed that Apple started developing a more affordable version of the Vision product in 2022, internally codenamed “N109.” According to the report, Apple is also trying to reduce the weight of the budget version by at least one-third compared to the Vision Pro. It is further reported that Foxconn will replace Luxshare as the manufacturer for Apple’s affordable MR device.

Industry sources cited by the same report indicated that Apple has already announced Apple Intelligence, confirming that AI applications will be integrated into all future devices. The next generation of MR devices, featuring more AI functions and applications along with a more affordable price, is expected to boost demand and significantly increase shipment volumes, benefiting Foxconn.

Other Taiwanese collaborators are also poised to benefit. GSEO has gradually been obtaining orders from the supply chains of Sony, Meta, and Apple, providing lenses and components for VR/MR headsets. GSEO expects VR-related applications to account for 20-30% of its revenue this year.

GIS plays a crucial role in the Vision Pro supply chain, handling the most technically challenging lens bonding tasks. Its production base is located in Chengdu, China, and it is generally anticipated to be part of the supply chain for Apple’s affordable MR headset as well.
