In the chip itself? No.
The packaging and interconnects often contain gold however.
There is a type of discrete bipolar junction transistor that is doped with gold, but as far as I have been able to find this is not used in ICs.

Thousands, if not millions. There are so many that it would be a major task to catalog them all. They could be categorized by technology used or by function.
Its not about size, its about controls. If the unit has a control board with IC chips, it uses a glow plug. If it uses mechanical switches, as most older units do, it will have a pilot.
IC Bus was created in 2002.

Huh? Very Large Scale Integration is a packaging density of IC chips. IC chips are a manufactured product that people make on special assembly lines. Does that answer your question?

You make computer chips and most ic devices from this material.
The operation of subtraction is just the inverse of addition, if you can do one you can do the other. BTW, are you thinking analog or digital IC? If digital there are ALU IC chips that do both, depending ..
LM is a manufacturer's code--all LM chips were made by National Semiconductor. Similarly, SN chips were made by Texas Instruments.
All computer chips have been made out of transistors, you cannot make them out of vacuum tubes. The first monolithic IC chip (see image above) was made at Texas Instruments in 1958 on a bar of germanium (not silicon), it was a simple audio amplifier. The first digital logic monolithic IC chips were built around 1961 or 1962.

Gold is the only conductor of electricity in which there is no voltage drop.
