IC is often said to be an integrated circuit, which is a general term for semiconductor component products. It uses a semiconductor production process to make many transistors and resistors, capacitors and other components on a small monocrystalline silicon sheet, and combines the components into a complete electronic circuit according to the method of multi-layer wiring or tunnel wiring.
IC(internal circulation) internal circulation, anaerobic reactor (referred to as IC reactor), is the third generation of efficient anaerobic bioreactor successfully developed by PAQUES in the Netherlands in the mid-1980s on the basis of UASB reactor (upflow anaerobic sludge bed).
