<CoolCmos>
im not up on terminology, but i was wondering if anybody can explain the conductive layer
<CoolCmos>
im also wondering about the alignment steps between layers
<CoolCmos>
can anybody help me out please
<CoolCmos>
have i wore out my welcome, or are people just busy
<sync>
what conductive layer?
<sync>
the metal layer?
<CoolCmos>
yes
<sync>
you just have fiducials
<sync>
just like you have on every other litho layer
<CoolCmos>
yes markers
<CoolCmos>
tho my experience with litho is very primitive
<CoolCmos>
what is the best method of etching and remval of the metal layer
<sync>
lapping
<sync>
as you have to get rid of the sio2 insulating it as well
<CoolCmos>
my first test is going to be without a metal layer, tho upon success which im hoping for, i want to be ready to move onto metal layers to complete ciruitry
<sync>
what are you trying to do?
<CoolCmos>
make my first vlsi circuits
<CoolCmos>
is that what yuo ment
<CoolCmos>
the primary test i will just use conductive epoxy and large contact areas on the circuit to test the NPN or PNP transistors
<CoolCmos>
that is more detailed
<CoolCmos>
ive been working with FPGAs for years
<CoolCmos>
they are too limited
<CoolCmos>
i covered intro to vlsi im my coputer engineering courses
<CoolCmos>
then later purchased several vlsi fab books
<CoolCmos>
ive read thru them several times.. but im still in the dark in many areas
