Auros是三星/SK海力士供应商，受益于HBM4混合键合计量和薄膜厚度测量两大产品线的量产增长。

涉及标的： $KLA

中文翻译

所以我确实认为Auros (322310)在韩国是一家市值2.69亿美元、非常有趣的公司。我从研究中发现，他们是一家相对不知名的三星/SK海力士供应商。而且他们应该会从HBM4资本支出的混合键合计量(Hybrid Bonding Metrology)中获得高产量增长。基本上是纯粹专注于两种产品： -> HBM4 / HBM4e / HBM5周期，之前$KLA在红外(IR)计量领域拥有垄断地位。 ---> 现在可能在三星工厂获得资格，下半年产能增长预计。SK海力士在升级到混合键合时也可能获得资格。关于SK海氨酸的注意事项：我以为会是HBM4e，但显然Trendforce今天报道SK海力士已完成12层混合键合HBM验证，并正在提高量产良率。所以除了三星之外，可能还有一个催化剂。 -> 薄膜厚度测量(Thin-film thickness measurement)。 ---> 现在正在获得资格，与"主要国内芯片制造商"(可能是三星/SK海力士)合作，目标是今年实现批量供应。免责声明(我持有仓位，不构成投资建议，请自己做尽职调查，这只是我的思考过程) 无论如何，他们在过去十年一直在开发，终于要从多年资格认证中将两种核心产品投入量产，可能是今年下半年。存在风险，例如不进入大批量生产(HVM)，但我个人承担这个风险。所以我发现这家公司非常有趣，只是想分享一些关于这家公司的想法。

So I do think Auros (322310) is very interesting at $269M MC over in Korea. What I've found from research was that they're a relatively unknown Samsung / SK Hynix supplier. And they should high volume ramp from HBM4 capex for Hybrid Bonding Metrology. Basically pure play on two products: -> HBM4 / HBM4e / HBM5 cycles, that $KLA had a monoply over for IR metrology. ---> Getting qualified now likely in Samsung factories, H2 volume ramp est. Sk Hynix likely qualifying too when they upgrade to hybrid bonding. Note on SK Hynix: I thought it would be HBM4e but apparently Trendforce reported today SK Hynix has completed 12-high hybrid bonding HBM validation and is raising yields for mass production. So maybe there's a catalyst there too aside from Samsung. -> Thin-film thickness measurement. ---> Getting qualified now, with "major domestic chipmaker" (likely Samsung/Sk hynix), targets mass supply this year. Disclosure (I do have positions, NFA, please do your own DD, this is just my thought process) Regardless, they've been developing for the past decade, only to volume ramp two core products from years of qualification likely H2 this year. There are risks involved, such as not proceeding to HVM, but I'm personally taking that risk. So I found this company very interesting, just wanted to publish some thoughts on this company.
