This week’s episode looks at EUV as part of a broader manufacturing system rather than a standalone scanner story. South Korea’s cluster plans, Micron’s record quarter, SK Hynix’s proposed U.S. listing, Dutch pushback on export controls, ASML’s photonics work with TNO, and xLight’s light-source ambitions all point to the same theme: future lithography capacity is being financed and managed like strategic infrastructure. Key takeaways: - South Korea is preparing a new southwest semiconductor hub, with local reports suggesting investments could exceed 1,000 trillion won over several years. - The expected South Korean support package is infrastructure-heavy: power, water, land, workforce training, transport, and housing all matter for EUV-ready capacity. - Micron reported record fiscal Q3 revenue of $41.46 billion and said data-center revenue exceeded $25 billion in the quarter. - Micron has signed 16 strategic customer agreements and expects memory tightness to persist beyond calendar 2027. - Micron projects fiscal 2026 capex of about $27 billion and expects higher quarterly capex in fiscal 2027, with construction capex driving more than half the year-over-year increase. - SK Hynix plans to raise up to 45.45 trillion won, or about $29.4 billion, through a U.S. American Depositary Receipt listing. - Dutch officials are pushing back against the MATCH Act because it could force allies into U.S.-style China export controls and affect DUV servicing. - ASML and TNO will use DUV and I-line lithography in a new Eindhoven pilot line for six-inch indium phosphide photonic chips. - The xLight $350 million fundraising item remains reported rather than officially announced; the official anchor is the June 2 U.S. CHIPS Act award. - This week’s focus is a mixed-fleet view of lithography: EUV carries the densest layers, but DUV still carries much of scale, yield, reliability, and cost.

[045] Deep Dive Topic - Decodes imec's new logic innovations

This post was created using AI. Please check the information if you want to use it as a basis for decision-making. Episode teaser This episode decodes imec's new logic innovation roadmap and explains why future scaling is no longer just about smaller transistors. We walk through the real physical metrics behind node names, the shift from FinFETs to nanosheets and CFETs, the role of High NA EUV, backside power delivery, CMOS 2.0, and active interposers. The focus is on the engineering trade-offs that make the roadmap technically credible, difficult, and important. Key takeaways - Node names are roadmap labels, not literal feature sizes. - Real scaling is better understood through contacted poly pitch, cell height, and metal pitch. - Gate-all-around nanosheets improve channel control and give designers a new drive-current versus area trade-off. - Forksheets may extend the nanosheet era, while CFETs promise tighter logic density through vertical transistor stacking. - High NA EUV improves imaging resolution but requires a new optical, mechanical, mask, and process ecosystem. - Backside power delivery attacks routing congestion and voltage loss by moving power wiring to the wafer backside. - CMOS 2.0 reframes scaling as a three-dimensional system-partitioning problem. - Active interposers could bring memory, photonics, capacitance, and voltage regulation closer to compute. - The future logic roadmap depends on co-optimizing devices, lithography, interconnect, power, packaging, and design tools. Glossary Contacted poly pitch: A physical spacing metric related to the distance between neighboring transistor gates in a standard logic cell. Cell height: The vertical size of a standard logic cell, often expressed in routing tracks. Reducing it improves density but constrains wiring and power resources. Metal pitch: The center-to-center distance between neighboring metal interconnect wires. It strongly affects wiring density and signal delay. FinFET: A fin-shaped field-effect transistor in which the gate controls multiple sides of a raised silicon channel. Gate-all-around transistor: A transistor architecture where the gate surrounds the channel on all sides for stronger electrostatic control. Nanosheet transistor: A gate-all-around transistor using stacked horizontal sheet-like channels. CFET: Complementary field-effect transistor. A future transistor architecture that vertically stacks n-type and p-type devices to reduce standard-cell footprint. High NA EUV: High numerical aperture extreme ultraviolet lithography. A next-generation EUV platform intended to print smaller features with improved resolution. Backside power delivery: A chip architecture that routes power from the wafer backside rather than through the frontside signal wiring stack. CMOS 2.0: Imec's concept for partitioning a system-on-chip into optimized functional tiers connected by dense 3D interconnects.
