So I'm looking through $MRVL SEC filings for fun over the weekend.
For constraints they're citing:
"advanced wafer fabrication, advanced packaging, and large body substrates."
which results in increased lead times, inability to meet demand, and increased costs...
-> So $TSM is Marvell's sole source foundry for all of our advanced process-node wafers according to their filings (no surprise there).
the less obvious one is Large Body Substrates to look at:
ABF substrates are already known, but lage body substrates might be a more acute bottleneck inside ABF.
There's..
Daeduck Electronics (353200)
Kinsus (3189) - "large-area high-layer-count ABF substrates" already up +496.07% YTD tho
LG Innotek (011070) - Large AI substrates with "Developing large AI substrates with a NA Big Tech customer, mass production beginning H2 26"
$ATS +370.12%
for the "lesser known" names outside of Ibiden, Nan Ya PCB, and Unimicron (but many have already rerated).
In May they worded it as supply challenges have occurred / may occur and large-body substrates were in a continuing tight environment.
Now it's "We are currently in a supply constrained environment."
Maybe there's more emerging players that I missed that I'll go hunting for.
But just disclosure on what acute bottleneck $MRVL is facing.

所以我周末闲着翻看 $MRVL 的 SEC 文件。
他们提到的限制因素是:
“先进晶圆制造、先进封装和大尺寸基板。”
导致交期延长、无法满足需求、成本上升……
→ 根据文件显示,$TSM 是 Marvell 所有先进制程晶圆的唯一代工(这并不意外)。
较不明显的因素是大尺寸基板,需要关注:
ABF 基板已经为人所知,但大尺寸基板可能是 ABF 内更紧迫的瓶颈。
有……
Daeduck Electronics (353200)
Kinsus (3189) - “大面积高层数 ABF 基板”,今年迄今已上涨 +496.07%
LG Innotek (011070) - 大型 AI 基板,文中称“与北美大型科技客户合作开发大型 AI 基板,量产预计 26 年下半年开始”
$ATS +370.12%
这些是 Ibiden、Nan Ya PCB、Unimicron 之外的“较不为人知”公司(但许多已被重新评级)。
5 月时他们的表述是供应挑战已出现/可能出现,且大尺寸基板仍处于持续紧张的环境。
现在的说法是“我们目前正处于供应受限的环境”。
也许还有我遗漏的其他新兴玩家,我会去寻找。
这只是披露 $MRVL 正面临的急性瓶颈。
