Patent ID: 11881508
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A method of fabricating a semiconductor device, the method comprising:
forming a preliminary insulating layer on a substrate;
performing a bake process on the preliminary insulating layer while providing an oxygen source onto the preliminary insulating layer;
injecting a light species into the preliminary insulating layer by performing a first ion implantation process;
forming a silicon oxide layer from the preliminary insulating layer by performing a wet annealing process on the preliminary insulating layer,
forming a gate electrode on the substrate after forming the silicon oxide layer; and
forming an interlayer insulating layer to cover the gate electrode,
wherein forming the interlayer insulating layer includes performing a second ion implantation process using the light species,
wherein the first and second ion implantation processes are each performed at a temperature of 200° C. to 600° C., and
wherein the light species includes H, He, C, N, O, Ar, Kr, or Xe.
