no i am not.

i just believe i'm in the right camp for the long run.

Thanks, Amy.  I feel smarter already.
@Cypherdoc:  I take it you're still on the payroll?

So, even though you can't say anything, I would guess that you're roughly at about step 128 of 247 total....

For those of you wondering how things are going with our chip fabrication, the answer is: Quite well. Everything at the foundry is on schedule (which believe me we are watching like a hawk every day!)

Unfortunately, our agreements with TSMC forbid us going into much, if any, detail about where exactly in the process our wafers are. 'Cause that would be telling.

On the other hand, nothing forbids me writing a general educational article on semiconductor fabrication.

And today, I'd like to introduce you to Front End of Line (FEOL) and Back End of Line (BEOL) fabrication. And the moment in between, when a foundry switches from one to the other.

Front End of Line is the first half of the process, where all the transistors are created.

"FEOL processing refers to the formation of the transistors directly in the silicon. Some steps include growth of the gate dielectric (traditionally silicon dioxide), patterning of the gate, patterning of the source and drain regions, and subsequent implantation or diffusion of dopants to obtain the desired complementary electrical properties."  -- Wikipedia

Back End of Line is the second half of the process, where those transistors are wired up together. An insulating layer is deposited, metal wiring created on top of it, then another layer of insulation, and vias - metal tunnels - to connect layers. They form the wiring that connects the transistors.

"BEOL processing involves creating metal interconnecting wires that are isolated by dielectric layers. The various metal layers are interconnected by etching holes (called "vias") in the insulating material and then depositing [metal] in them. BEOL includes contacts, insulating layers (dielectrics), metal levels, and bonding sites for chip-to-package connections."

The point when the first half of the process (FEOL) is done, and the second begins (BEOL), is an entirely artificial but highly satisfying milestone on the way to finished chips.

Some call it 'Contact', some call it the start of metallization, some just call it progress.

And thus ends my lesson on generic semiconductor manufacturing practices!

well, i'm not as annoyed as you might want me to be. 

it's just that they asked me to pre-announce yesterday afternoon with the expectation that they'd f/u within a short time period.  no biggie.  it's coming soon.

Why would you be annoyed? You're the one that went out and announced that there was going to be an announcement.

As someone else noted...  no need for a pre-announcement of an announcement.....  Just wait for the blog to be posted.  And by the way, if the news is anygood, it will not need help getting around

Maybe other people don't bother wasting time to teach you or Hashfast how to do their PR job...

I must admit, you're not the only one annoyed.

I have never figured out the whole "pre-announcement of announcements" thing.  Why not just come out and say what you have to say when it's time to say it??  

I mean, it's not like I'm going to run to the site and hit F5 to refresh the page every few seconds for the next 24 hours so I can be the very first person to read it...

Yes, quite an annoying technique.

But it did prompt jjiimm_64's joke, which was the funniest thing I read yesterday !

What lousy PR. "Imminently" meaning more than 12 hours? Or you just wanted to create some useless traffic on their blog?

I posted in the other thread but I will post here it again anyway.

Contact is about chips layering and they will also post something about that they are still on promised delivery times.

Lets wait for the blog update for more details 

Contact is a new case, or the contact with the chips?
A bit too early for the chips, i guess..

Correct.

This is not correct. As far as I'm able to understand, BitFunder is working as usual for all non-US citizens. Except that you need a verified status on WeExchange after 1.November. That probably means passport scan + proof of residence address.

Slightly off topic but did anyone here invest in IceDrill.ASIC shares on BitFunder?  That was the mining operation that will be using HashFast's tech.  BitFunder announced today that all use users of the platform need to liquidate their positions by the end of the month.  I'm curious if anyone here has any thoughts on if that will affect HashFast and if there are any options besides selling shares by Nov. 1 for US investors?

What is contact?

?    announcing contact..... with alien intelligence
