Stay updated on the latest trends and breakthroughs in the electronics industry with SLKOR Semicon

China Tech Highlights

1. China Implements New Chip Regulations, Imposes 125% Tariffs on U.S. Semiconductor Firms

   • The China Semiconductor Industry Association introduced new rules defining "place of tape-out as origin," imposing a 125% tariff on chips manufactured in the U.S. This has prompted companies like Texas Instruments and Intel to accelerate production capacity expansion in China.

   • The policy is accelerating domestic chip substitution, with SMIC achieving a 99% yield rate for 14nm automotive-grade chips, and BYD Semiconductor reducing IGBT module costs by 40%.

2. U.S. Exempts Tariffs on Some Chinese Tech Products

   • U.S. Customs and Border Protection (CBP) announced exemptions for 352 categories of Chinese tech imports, including smartphones and computers, from the 125% tariffs to ease domestic inflation.

   • China’s Ministry of Commerce responded by stating it would maintain retaliatory tariffs on U.S. automotive and chemical products.

3. China Successfully Launches Satellite Internet Test Satellites

   • On April 1, the Long March 2D rocket launched four experimental satellites for satellite internet, using Ka-band technology to enable direct smartphone connectivity without additional terminals.

4. Breakthroughs in Quantum Computing and Communication

   • China launched the world’s first quantum micro-nano satellite, "Jinan-1," and achieved over 10,000 km of satellite-to-ground quantum key distribution. The "Zuchongzhi-3" superconducting quantum computer set new computation records.

   • Indonesia announced plans to adopt China’s quantum encryption technology for its national government communications network.

5. AI and Large Model Developments

   • Shanghai AI Lab open-sourced its multimodal model "InternLM-XComposer 3.0," supporting text, image, and other multimodal inputs.

   • ByteDance released its "Doubao 1.5" model, featuring "visual reasoning" capabilities for enterprise AI services.

International Tech Highlights

1. U.S. Suspends Restrictions on H20 AI Chips

   • The Trump administration halted export controls on Nvidia’s H20 AI chips after the company pledged to increase AI data center investments in the U.S.

2. OpenAI and SoftBank May Invest $500 Billion in UK AI Compute Center

   • The project, codenamed "Stargate," aims to advance next-gen large model development and could reshape the global AI industry.

3. World’s First Humanoid Robot Half-Marathon to Be Held

   • On April 19, robots like Boston Dynamics’ Atlas and Tesla’s Optimus will compete, testing mobility and environmental adaptability.

4. Nokia and Zayo Europe Complete 800Gb/s Ultra-Long-Haul Optical Transmission Test

   • Achieved 800Gb/s single-wavelength transmission over 1,000 km in a live network (Paris to Marseille), improving spectral efficiency by 33%.

5. Samsung Begins 1nm Process R&D

   • Samsung reassigned its 2nm team to focus on 1nm development, targeting mass production of 1.4nm by 2027 and advancing toward 1nm.

Summary

This week’s tech industry was dominated by chip tariff wars, quantum computing breakthroughs, AI model advancements, satellite internet, and semiconductor process competition. China made strides in quantum tech, satellite communications, and chip self-sufficiency, while the U.S. adjusted policies on AI infrastructure and semiconductors. Global tech competition continues to intensify, driving rapid industry restructuring.
