Rapid thermal processing (or RTP) refers to a semiconductor manufacturing process which heats silicon wafers to high temperatures (up to 1200 C or greater) on a timescale of several seconds or less. The wafers must be brought down (temperature) slow enough however, so they do not break due to thermal shock..Such rapid heating rates are attained by high intensity lamps process. These processes are used for a wide variety of applications in semiconductor manufacturing including dopant activation, thermal oxidation, metal reflow and chemical vapor deposition.
Rapid thermal anneal (RTA) is a process used in semiconductor device fabrication which consists of heating a single wafer at a time in order to affect its electrical properties. Unique heat treatments are designed for different effects. Wafers can be heated in order to activate dopants, change film-to-film or film-to-wafer substrate interfaces, densify deposited films, change states of grown films, repair damage from ion implantation, move dopants or drive dopants from one film into another or from a film into the wafer substrate. Rapid thermal anneals are performed by equipment that heats a single wafer at a time using lamp based heating that a wafer is brought near. Unlike furnace anneals they are short in duration, processing each wafer in several minutes. Rapid thermal anneal is a subset of processes called Rapid Thermal Process (RTP).
