  • Patent number: 11631807
    Abstract: Aspects of the present technology are directed toward Integrated Circuits (IC) including a plurality of trenches disposed in a substrate about a set of silicide regions. The trenches can extend down into the substrate below the set of silicide regions. The silicide regions can be formed by implanting metal ions into portions of a substrate exposed by a mask layer with narrow pitch openings. The trenches can be formed by selectively etching the substrate utilizing the set of silicide regions as a trench mask. An semiconductor material with various degree of crystallinity can be grown from the silicide regions, in openings that extend through subsequently formed layers down to the silicide regions.

  • Patent number: 11569440
    Abstract: The invention disclosed a method to make an implanted hard mask with ultra-small dimensions for fabricating integrated nonvolatile random access memory. Instead of directly depositing hard mask material on top of the memory film stack element, we first make ultra-small VIA holes on a pattern transfer molding (PTM) layer using a reverse memory mask, then fill in the hard mask material into the VIA holes within the PTM material. Ultra-small hard mask pillars are formed after removing the PTM material. To improve the adhesion of the hard mask pillars with the underneath memory stack element, a hard mask sustaining element (HMSE) is added below PTM. Due to a better materials adhesion between HMSE and the hard mask, a stronger hard mask array can be formed.
