Publication number: 20140151760Abstract: A method of filling gaps between gates with doped flowable pre-metal dielectric (PMD) and the resulting device are disclosed. Embodiments include forming at least two dummy gates on a substrate, each dummy gate being surrounded by spacers; filling a gap between adjacent spacers of the at least two dummy gates with a flowable PMD; implanting a dopant in the flowable PMD; and annealing the flowable PMD. Doping the flowable PMD prevents erosion of the PMD, thereby providing a voidless gap-fill.Type: ApplicationFiled: December 4, 2012Publication date: June 5, 2014Applicant: GLOBALFOUNDRIES Inc.Inventors: Haiting WANG, Po-Wen CHAN, Yan Ping SHEN, Yong Meng LEE
