    This Innovation Could Make the Perfect Silicon Chip—and End Moore’s Law

    It's slow, like epitaxy, to keep the crystalline order.

    This Innovation Could Make the Perfect Silicon Chip—and End Moore’s Law

    A/MLD is a slow, i.e., expensive, way of depositing photoresist, compared to standard spin-coat.

    Chinese DDR5 RAM: Is This the Solution to Crazy Memory Prices?

    CXMT is providing decent DDR5, although the notorious price drop from some weeks ago is now no longer the case. The DDR5 nightmare hasn't eased yet, but today we're checking out an option that might be viable for anyone who needs to get their hands on some memory. As we're all painfully aware...

    More Clients Leads to 80% Utilization at Samsung Foundry in 1Q2026

    I had heard about ANAFLASH's 28nm edge AI project back in November: https://www.businesswire.com/news/home/20251103252346/en/ANAFLASH-Advances-Embedded-FLASH-Memory-for-Next-Generation-Smart-Edge-Devices-with-Samsung-Foundry I'd be curious and eager to know if their 8nm eMRAM gets any design...

    Samsung enlarges 1c DRAM die size, yields stuck at 60%

    Jukan's source for this post is a ZDNet article: https://zdnet.co.kr/view/?no=20260225154303#_enliple Samsung Electronics' breakthrough was the "enlargement of the chip size" of its 1c DRAM. Around the end of 2024, Samsung Electronics decided to revise some of its 1c DRAM design. The key point...

    Samsung enlarges 1c DRAM die size, yields stuck at 60%

    Samsung Electronics made the decisive move to enlarge the die size of its core die, the 1c (6th-generation 10nm-class) DRAM. A larger die size can simultaneously improve the stability of both DRAM and HBM4. However, this decision works unfavorably from a profitability standpoint, as it reduces...

    Exclusive-ASML unveils EUV light source advance that could yield 50% more chips by 2030

    Exactly. Higher heating and stronger EUV-induced plasma effects, resist degrading/thinning faster.

    Panther Lake design rules revealed, no HD cells

    We've heard that 18A yields were still on improvement path toward the end of 2025. Parametric yields could also result from stochastics as manifested in uniformity. But EUV yield is intrinsically erratic, since the D0 (from stochastics) can vary over an order of magnitude.

    Panther Lake design rules revealed, no HD cells

    If Backside or GAA/RibbonFET are new sources of yield loss, then relaxing to 36 nm pitch looks understandable. That said, high defect density at 36 nm pitch has been noted publicly before by imec, Samsung, and even (indirectly) TSMC.

    Panther Lake design rules revealed, no HD cells

    Some key Panther Lake design rules were posted on X: Minimum pitch 36 nm (7nm-class), density obviously helped by 5 tracks from backside rails.

    Did Intel just delay their 14A node by a year?

    Did Intel just delay their 14A node by a year? At Cisco's AI Summit this month, Intel CEO Lip-Bu Tan announced that Intel's 14A node will be in risk production in 2028 and volume production in 2029, representing a 1 year slip from prior disclosures of a 2027 risk production start date. The...

    SMIC BEOL photolithography process analysis / N+3 yield issues

    Yes, a 32 nm pitch direct EUV print is highly risky and ppm-level defect probabilities have already been reported in several published sources (besides myself, Samsung/ASML and imec/Siemens) for 40 nm pitch and below. Probably even more difficult is the wide range (over an order of magnitude) of...

    SMIC BEOL photolithography process analysis / N+3 yield issues

    Ok, I'm not sure if the author is doing solely a speculative analysis or has the teardown. Author mentions five M0 tracks, but the cell height is determined by six 38 nm pitch M2 tracks (=228 nm). I had the understanding that TechInsights did the analysis for this, so I'm not sure if that is...
