Depends on what you're looking for. In a previous life we subscribed to some semiconductor analysis pubs that we're insanely deep dives into the industry. But they weren't so much technical deep dives as stuff a industry sector trader wants to know. And AFAIK they were very, very expensive.
I'm there with you. I keep an eye out for IEEE pubs, and papers out of schools that have microelectronics specialist programs, and the occasional vendor pub that isn't marketing, but there doesn't seem to be a rollup site for curated deep dives.
