发明名称 Method for forming a self-aligned contact opening by a lateral etch
摘要 A self-aligned source/drain contact formation process without spacer or cap loss is described. Embodiments include providing two gate stacks, each having spacers on opposite sides, and an interlayer dielectric (ILD) over the two gate stacks and in a space therebetween, forming a vertical contact opening within the ILD between the two gate stacks, and laterally removing ILD between the two gate stacks from the vertical contact opening toward the spacers, to form a contact hole.
