I work for a company that has clients in the semiconductor industry, such as Intel. We clean some of the expensive parts and equipment they use, what is my occupation?

We clean the parts they use to make their microchip wafers, cleanroom setting, etc. We use strong chemicals (i.e. hydrofluoric acid, nitric acid, sulfuric acid, etc.. It's not like housekeeping cleaning services) to make sure their parts are completely clean and free of any contaminants. I am not sure what industry this falls into, is it manufacturing?

It's not important what you put for your occupation on your tax return. Don't stress over it. You can put something vague like electronics fabrication or electronic parts processor.
