welcome back to my YouTube channel
0:01
called silicon vlsi in today's video we
0:04
are discuss about finfet what is the
0:06
finfet and their advantage and
0:09
disadvantage so let's start the video
0:12
first let's start the basic with
0:14
finfet finfet 10 for fin filled effect
0:18
transistor it's a type of non planner or
0:21
3D transistor that used in modern
0:24
semiconductor device unlike traditional
0:26
pan transistor fin pad have a thin fin
0:29
like structure structure that rise above
0:31
the substate thin film form a conducting
0:36
Channel think of like traditional mosfet
0:40
are flat but finfish stand up like a fin
0:42
or a fish which is where they get their
0:45
name this 3D structure allow for a
0:47
better control of the current flow
0:50
significantly improve the performance
0:52
and reduce the power
0:54
[Music]
0:55
consumtion let's start their advantage
0:59
so let's start first advantage of the
1:02
finfet
1:04
first most advantage of finfet is better
1:08
control of a short Channel effect in a
1:11
traditional mosit the transistor gets
1:13
smaller controlling the current become a
1:16
more challenging so finest 3D structure
1:19
helps to improve the issue making them
1:21
ideal and advanced smaller process not
1:25
so in another way we can say that finfet
1:28
is a better to reduce the dibl effect
1:32
what is the meaning of dibl di is the
1:34
drain induced barrier
1:37
lowering second most advantage of finfet
1:40
is a lower leakage current because of it
1:43
it 3D structure the gate control its
1:45
three shite so it reduce the significant
1:49
current leakage because finfet provide
1:52
better gate control this significantly
1:54
reduce the leakage current which is a
1:56
major benefit for low power applications
2:00
third advantage of finfet is higher
2:03
Drive current finfet can handle more
2:06
current through the channel due to their
2:08
multiple surface leading to better
2:11
performance and faster switching
2:14
speeds fourth advantage of INF is better
2:18
scalability as we continue push towards
2:21
the smaller and smaller node more
2:23
efficient transistor finfet offer a path
2:27
forward where the traditional pner
2:29
transistors
2:32
struggled so as you know that fin pad
2:35
have some disadvantage also as compared
2:38
to plan and Technology now let's discuss
2:41
about
2:42
finfet
2:45
disadvantage so first disadvantage of
2:48
finfet is a manufacturing complexity or
2:51
another way I can say is finfet have a
2:54
higher fabrication
2:57
cost as you know like in the plant we
3:00
have F oil and B oil in a fabrication
3:03
point of view like what is the meaning
3:05
of f oil F oil means front end of fly
3:10
what is the meaning of b
3:12
o page backend end off
3:16
fly while INF fin fet we have a third
3:19
three step f o m o b e o mu me middle
3:27
end of fline
3:31
so the 3D structure of infed make them
3:34
more difficult and expensive to
3:37
manufacture compared to the traditional
3:39
planner transistor this complexity can
3:41
lead a higher Pro production cost second
3:46
design challenges is design challenges
3:49
design circuit with finfet require new
3:52
tool and
3:54
methodology which means a step learning
3:58
curve and potential delay in development
4:01
the third disadvantage of finfet is
4:05
thermal issue the increasing packaging
4:08
density and unique structure of finfet
4:11
can lead to Thermal management
4:14
challenges which must be carefully
4:17
addressed during the design and
4:20
Manufacturing in summary we can say that
4:23
finet represent a significant
4:26
advancement in a transistor technology
4:29
offering numerous benefits such a better
4:31
control of a sord channel effect lower
4:34
leakage current High Drive current and
4:36
better scalability however they come
4:39
with challenges like increase
4:41
manufacturing complexity design
4:43
challenges and potential thermal
4:50
issue despite of these challenges the
4:53
advanc advantage of finfet make them a
4:56
key plan player in the future of the
4:59
semiconductor technology as we continue
5:01
to push the boundary of what possible in
5:04
electronics pinet will undoubtfully play
5:09
important role in the future
5:12
technology so this is all about
