Why do they not "stick" ?

Just came across another "suggested alternate to ArFi" litho - http://www.nanowerk.com/nanotechnology_articles/newsid=47727.php - "self-collapse litho" In fact the article itself lists various other "molecular patterning strategies" that are/were tried - s oft lithographic microcontact printing (µCP), replica molding, nanoimprint lithography, polymer pen lithography, nanotransfer printing, decal transfer printing, and nanoskiving. Add to it the "multi ebeams" and DSAs and then those fancy named ones - SCALPEL:Scattering with angular limitation projection electron beam lithography ; PREVAIL: Projection Reduction Exposure with Variable Axis Immersion Lenses ; LEEPL: Low Energy Ebeam Projection Litho ..       Nothing "stuck" -pun intended - on the wafer ! Closest seems to be EUV, but thats yet again changing the source for a mask-based litho.. indeed in this case the change to a reflective system is a big one Con...

My nano-life

Some one once told me this math - 52 weekends in a year. So how many weekends in your life ? Come this Nov, I as "Arun" would have already completed 38 years on earth. If - and thats a big if - I don't get rammed down by a speeding car while crossing a road, or not beaten to death by a mob (as my wife always says, given my nature of picking up arguments with random people when I feel something is wrong), or taken over by a failed liver or so (yes, in spite of being a non-alcoholic) -- I expect may be 12 more years of "active life". That gives me about 600 weeks - 600 weekends as well. Now, here is another math... In a week, assume a 9hr sleep, you are awake for 15 X 7 , 105 hrs.. Let say 2 hrs per day for daily routine, that leaves you with 90hrs. You are "paid" for 40hr per week at work - let us say practically you spend 50 hrs, and 10 hrs on commute, that still leaves you with 30hrs a week. Add some weekend outings and relaxation time of 1...
