Remove the blob to expose the silicon die. That means there are very fine gold leads from the board to the die connecting plates or areas. With out the protective blob the microfine connections would be damaged. In business all things put in place are reasonable.
A rom is an IC. A resistor ladder on ceramic is an IC. A bare die serves no purpose. What is on the boards is an etched die. Silicon circuits are not effected operationally by air except to remove thermal build up. ASICs perform a specific product function whether logic, data or analog process.

According to Wikipedia; Under Waffer Slicing;

'These will be packaged in a suitable package or placed directly on a printed circuit board substrate as a "bare die".'

Those motors are ASIC's because commercial motors often require factory
custom made semiconductors.

Those pictures are of ASIC's mounted as "bare die".

Think again, giantkiller you don't know much..Don't argue with me, argue with Wikipedia!

hey how many french men to screw in a light bulb .. 

answer 1001 .. 

1 to hold the bulb the other 1000 to turn the house ..

ist!

whats up guys and gals..
i was wondering whats is the best circuit for a transformer with two leads going in on the primany 1-9 volts..
i got the push and pull right now the pnp and npn transistors together.. i was wondering if there is a better and lower draw circuit to use..
hey check.. this i bought two cheap-o- stun guns at the flea market and modded them for a lower current draw and of course a lower output.. but if you hook them in reverse on the outputs and tap in to it you get some some crazy kool output power..weird thing is it seems to be dc volts
but i got them for 10$ each and there rechargable.. i just got them for parts..but i am having to much fun with them..
already zapped myself..  but thats alright my life is limited anyway..

let me know
