Patent number: 11965239Abstract: Provided is improved methodology for the nucleation of certain metal nitride substrate surfaces utilizing certain silicon-containing halides, silicon-containing amides, and certain metal precursors, in conjunction with nitrogen-containing reducing gases. While utilizing a pretreatment step, the methodology shows greatly improved nucleation wherein a microelectronic device substrate having such a metal nitride film deposited thereon has a thickness of about 10 ? to about 15 ? and less than about 1% of void area. Once such nucleation has been achieved, traditional layer-upon-layer deposition can rapidly take place.Type: GrantFiled: January 28, 2021Date of Patent: April 23, 2024Assignee: ENTEGRIS, INC.Inventors: Gavin Richards, Thomas H. Baum, Han Wang, Bryan C. Hendrix

Patent number: 11932935Abstract: Provided is a process for the rapid deposition of highly conformal molybdenum- or tungsten-containing films onto microelectronic device substrates under vapor deposition conditions. In the practice of the invention, a first nucleation step is conducted, while utilizing a generally lower concentration of metal precursor than would ordinarily be utilized in the reaction zone. This utilization of lower metal precursor concentrations can be achieved by way of regulating the temperature of the ampoule (housing the precursor), the concentration of the precursor, pressure in the reaction zone, and the duration of the pulse. In this fashion, a generally lower concentration is utilized to form a nucleation layer of greater than or equal to about 3 ?, or up to about 9, 15, or 25 ?, at which time, the conditions for introducing the precursor are advantageously changed and the concentration of the precursor in the reaction zone is increased for the purpose of bulk deposition.Type: GrantFiled: May 6, 2022Date of Patent: March 19, 2024Assignee: ENTEGRIS, INC.Inventor: Robert L. Wright, Jr.
