LM stands for "NATIONAL SEMICONDUCTORS". i.e, that particular ic has been manufactured by "NATIONAL SEMICONDUCTORS".
infact on any ic two letters indicate the manufacturing company's name,eg MC stands for Motorola(now freescale),SN for Texas instruments,NS for signetics, CM for California microelectronics and so on...
We don't generally "etch" integrated circuits, but, rather, we "grow" them layer by layer on a silicon substrate.
Two Integrated Circuit package types are Surface Mount and Through Hole.
Integrated circuits are not really a material, so nothing is made out of them. If you are wondering what THEY are made out of, then nobody will really be able to tell you, as there is more than one way to do it. (Silicon and Zinc oxide to name a couple)
used as wave form generators like sinusoidal and non sinusoidal,
Components such as resistors, capacitors and integrated circuits are generally made by specialized contractors. Integrated circuits are generally made by the process of photolithography. Printed circuit boards (PCBs) are usually manufactured by specialized contractors. The oldest technique was rouse humans to hand solder all components together.
BC stands for silicon transistor
LM stands for "Linear Monolithic"
Yes integrated circuits have polarity.

Both hybrid integrated circuits and monolithic integrated circuits were used in third generation computers. These integrated circuits contained from 4 to 100 transistors per integrated circuit. The image above shows hybrid integrated circuits of the type used in the IBM System 360 line of computers.
The disadvantages of integrated circuits include the limited range of IC resistors. Another disadvantage is that inductors cannot be formed using integrated circuits.

In America
Solid State Media consists entirely of electronic components, such as integrated circuits.
The two largest selling types of memory integrated circuits are DRAMs and SRAMs.
