Bunny people work at Intel! Ha! No not really. We just call them that because they have to wear these suites so that everything is really clean. They can’t risk having any dust or dirt getting on the chips. The silicon chips are the CPU’s in computers. They “perform mathematical operations and move data from one memory location to another. Microprocessors contain an address bus that sends addresses to memory, read and write lines, and a data bus that can send data to memory or receive data from memory.” According to the Information at GlobalSpec.
Technicians who work at Intel wear the bunny suites. Even a single particle of dust has a large effect when compared to the microscopic details of an Intel chip. Dirt would affect the proper functioning of the microprocessor so they take extra caution to be clean.
