Title: Selective metal growth method
Inventor: SATO JUNICHI
IPC: H01L21/285
Filed: 1990-05-25
Abstract: PURPOSE:To simultaneously satisfy both selective growth property and heat- resisting property by a method wherein a film, which becomes the seed for selective growth, is formed on the side wall of a contact hole, and after the film which develops into a heat-resisting film has been formed on the bottom part, metal is selectively grown and buried. CONSTITUTION:First, an insulating film of SiO and the like is formed on the surface of a silicon substrate 11, a contact hole 13 having the prescribed size is opened, and for example, a phosphorus-doped a-Si film 16 is formed on the whole surface for the purpose of lowering contact resistance. Then, a TiN film 17 is formed on the a-Si film 16. Subsequently, using a bias-application type ECR plasma treating device of the same high frequency or other plasma treating device, the RiN on the coarse section, namely, the TiN film 17a on the side wall is removed by plasma etching. Then, a W 18 is formed using a selective W-CVD method. At this time, as a W 18 is grown with the a-Si film 16 on the side wall 15 as the seed of growth, a contact hole 13 can be filled up. Subsequently, after the a-Si film 16 and the TiN film 17 on the upper part have been removed using an anisotropic method and the like, an upper part wiring is formed using a sputtering method and the like.
