Hello masters,
Is it possible to Design and fabricate IC Chip at home using some sort of photo etching or some thing...may be it will not be perfect ie let it consume more power,too big in size and etc.But logically it should work.
I think it must work with keil stuff.

It merely depends on how much money you are willing to spend. If that is not an issue, you can turn your home into a fab, complete with clean room and everything.
But then again, why spend upwards of seven figures to make an IC that's worth a few cents ? Especially when there's cheaper approaches, like using FPGAs.
Keil does not sell any tools that are used during IC hardware development.
Yes - of course it is, in theory, possible
But it would be entirely impractical and totally uneconomic!
You could try making thermionic valves (tubes) instead: www.dailymotion.com/.../x3wrzo_fabrication-dune-lampe-triode_tech
Even if you would have vast of fund, it is impossible, unless you are living in deep countryside. In most countries, explosive gas (silane: SiH4) and toxic gas (phosphine: PH3, diborane: B2H6) for plasma CVD are regulated not to use in town. If you would apply classic liquid-phase doping, you cannot waste the toxic chemicals to drain. Hydrofluoric acid (HF) for etching also.
If you could happily clear these prerequisite, it takes enormous time to establish the optimal conditions for process. After all, the result is the ancient 4000 series CMOS, at most.
I swear, because it was my study life on our lab, though it was more than 15 years ago. :-)

Is it possible to Design and fabricate IC Chip at home using some sort of photo etching or some thing are you aware that there are things like CPLD, FPGA ...
I think it must work with keil stuff. 'Keil stuff' does not work with 'chips' it program microcontrollers.

If you are designing it, then it would be up to you to make it so!
you could try a huge board with thousands of sot-23 transistors ;)
my serious answer...look into printed transistor method. It can be done if you can get the right materials. use silk print method.
Why?
Surely FPGA or similar has to be the way to go for home-made "custom" chips?!

That wouldn't be home-made - jsut working :)
Many old-timers made their first radio using a razor & safety-pin (Foxhole radio) This is a home-made diode

when you have a diode going, go on to make a transistor, then go on an a circuit.
easy ;)
Does anyone know how many transistors Intel used in the original 8032?
It would then be interesting to extrapolate the size of an 8032 built from individual hand-made, point-contact transistors...
Memory would be hand-woven magnetic core, of course...

Get the book on ebay: cgi.ebay.co.uk/.../eBayISAPI.dll
8008 had 3500 transistors. 8080 had 6000 transistors. 8085 had 6500 transistors.
The 8080 was a quite general 8-bit processor, but without any peripherials. The 8085 integrated (among other things) the clock generator.
It wouldn't be unreasonable to think that the original 8032 had somewhere around 5-6k transistors. The core is way simpler than the 8080 but to that comes the built-in devices for standalone microcontroller use.
