In recent years, RTP has been increasingly applied to the processing of magnetic materials. The iron ore ship loader
Rapid Thermal Processing - an overview ScienceDirect …
WebFurnaces are capable of processing many wafers at a time but each process can last between several hours and a day. Increasingly, furnace anneals are being supplanted by Rapid Thermal Anneal (RTA) or Rapid Thermal Processing (RTP). This is due to the relatively long thermal cycles of furnaces that causes the dopants that are being … Rapid thermal processing (RTP) is a semiconductor manufacturing process which heats silicon wafers to temperatures exceeding 1,000°C for not more than a few seconds. During cooling wafer temperatures must be brought down slowly to prevent dislocations and wafer breakage due to thermal shock. Such rapid heating rates are often attained by high intensity lamps or lasers. These processes are used for a wide variety of applications in semiconductor manufacturing incl… WebUnfortunately, several excellent ideas were invented too early when no market and application existed. This is probably the reason why Rapid Thermal Processing of semiconductors instead of going through a thorough and systematic scientific development followed a chaotic and spontaneous road of partial improvements.
