Q & A

Why was Japan once the leader in semiconductor manufacturing, and what happened to its dominance?

In the 1980s, Japan dominated the semiconductor industry, producing nearly 90% of the world's memory chips. They bet early on CMOS technology, which became cheaper and more efficient over time, giving them a technological edge. However, Japan's insular approach to chipmaking, focusing on designing, manufacturing, and packaging all in-house, caused them to fall behind as the industry evolved faster, and companies like TSMC adopted a more scalable model.

What is the significance of Japan's current push to re-enter the advanced semiconductor market?

Japan's re-entry into the semiconductor market is significant because it involves a multi-faceted effort to reclaim a leadership position. This includes collaborations with major global players like IBM and TSMC, and the creation of a cutting-edge 2nm chip manufacturing facility. Japan’s comeback could result in more innovation, better technology, and potentially lower-cost devices, as well as a reduction in global over-reliance on a few chip manufacturers.

What role does Rapidus play in Japan’s semiconductor revival?

Rapidus is a key part of Japan's semiconductor revival. This company, backed by the Japanese government and major corporations like Toyota, Sony, and SoftBank, is tasked with building one of the world's most advanced chip factories. They aim to produce 2nm chips with the help of IBM and IMEC. Rapidus is adopting a unique approach, manufacturing chips one wafer at a time for better control and precision.

What is Japan’s strategy for regaining its position in semiconductor manufacturing by 2027?

Japan’s strategy includes the construction of advanced semiconductor fabs with a focus on 2nm technology. The country is heavily investing, with a $67 billion plan to develop this industry. Key elements of their approach include collaborating with global players, bringing in cutting-edge equipment like EUV lithography machines, and fostering innovation in materials and chip design. The timeline to achieve this is ambitious, with the goal of having a functional fab by 2027.

What is the significance of the synthetic diamond chip technology Japan is exploring?

Synthetic diamond chips represent an exciting development in semiconductor technology. These chips can withstand extreme temperatures, high radiation, and harsh environments, making them ideal for use in aerospace, space exploration, and autonomous vehicles. Japan’s work in this area could pave the way for chips that are not only faster but also more durable and capable of handling conditions where silicon-based chips would fail.

How does Japan’s manufacturing approach differ from other chipmakers like TSMC and Intel?

Unlike most major chipmakers, who produce chips in large batches to save time and cost, Rapidus is adopting a 'one wafer at a time' approach. This method is slower but allows for greater precision and better quality control, especially in the early stages of production. Rapidus is prioritizing quality over speed, a strategy deeply ingrained in Japanese culture.

Why is Japan’s culture of 'Kaizen' important in semiconductor manufacturing?

The concept of 'Kaizen,' or continuous improvement, is central to Japan’s approach to manufacturing. In chipmaking, this philosophy ensures that every process is scrutinized and refined for greater efficiency and precision. It leads to high-quality products and a focus on long-term success, rather than cutting corners or rushing through production.

What challenges does Japan face in regaining its leadership in the semiconductor industry?

Japan faces several challenges, including stiff competition from established leaders like TSMC and Samsung. They also need to catch up in key areas like lithography machines, chip packaging, and AI memory. Despite these hurdles, Japan’s strong engineering talent, government support, and focus on quality could help them overcome these challenges if they stay focused and move quickly.

What are 'chiplets' and how are they being used in Japan's new Monaca CPU?

'Chiplets' are smaller, modular components of a larger chip, designed to mix and match different technology nodes to optimize performance and cost. In Japan’s Monaca CPU, 2nm chiplets are combined with 5nm memory to balance the cost of production with performance needs. This design approach allows for more flexibility and cost efficiency in building high-performance chips for supercomputers and scientific research.

How might Japan’s semiconductor efforts impact global chip supply and the broader tech industry?

If Japan succeeds in rebuilding its semiconductor industry, it could reduce the global over-reliance on a few key suppliers like TSMC and Samsung. This diversification would help stabilize the global chip supply, potentially leading to more innovation, lower prices, and better technology. It could also provide a backup in case of disruptions in the supply chain, ensuring the continuous availability of essential components for industries like automotive, AI, and consumer electronics.
