Patent ID: 7276121

Claim:
A reactor for forming a metal nitride (MN) comprising, a) a first container, b) said container having an upstream inlet, followed by a first boat for iodine (I 2 ), a second boat for M spaced downstream from said first boat and an outlet located downstream from said second boat, c) means to reduce the pressure in said container to below 760 Torr, d) means for heating the two boats, e) means for flowing iodine vapor from said first boat or for flowing hydrogen iodide (HI) from said inlet downstream to said second boat to contact said M to form metal iodide (MI) vapor and for flowing said MI vapor out said outlet, f) means to contact the outlet MI vapor with ammonia to form said MN g) means to vary the heat applied to the first boat to vary the vapor pressure of I 2 and h) means to vary the heat applied to the second boat to vary the formation rate of MI, to control the quality and/or quantity of the deposited MN.
