I'm just quoting to preserve one of the worst self-burns in the history of Bitcointalk. Please don't delete my post, although it is trivial. The ambiguity in English language grammar is such a trap: Pharmacist dispensed with accuracy.
You do realize mask is before tapeout, right?

No, no it's not.

uuuh, yeah, okay.


Oh I forget, this is the interweb, people feel entitled to their own reality.
You have that right I guess.
Doesn't change anything tho.
Did you even read them?

Mask is clearly a part of the design phase, and required BEFORE sent to fabrication,
and our chips have been sent to fab.  Unless Intel is wrong too, lol.
this may help you understand too... http://computer.howstuffworks.com/euvl1.htm

The mask itself is used in the lithography process to actually print onto the silicon. It's like a transparent photo that radiation is passed thru to burn the chip design onto the silicon, making the chips. When they submitted the artwork, or "mask" to the manufacturer, that was "Tapeout".

Since you obviously didn't read it....


You are in denial, and should begin a 12 step program maybe?... 
Masking is complete before it can be sent to fab, simple as that.
One cannot tapeout without having a mask done.
The mask itself is used to print the circuits, so it's impossible to tapeout without it, because tapeout is the sending of the mask to manufacture the wafer.
