Title (EN) METHODS OF FORMING SELF ALIGNED SPACERS FOR NANOWIRE DEVICE STRUCTURES
(FR) PROCÉDÉS DE FORMATION D'ESPACEURS AUTO-ALIGNÉS POUR STRUCTURES DE DISPOSITIFS À NANOFILS
Abstract:
(EN) Methods of forming self-aligned nanowire spacer structures are described. An embodiment includes forming a channel structure comprising a first nanowire and a second nanowire. Source/drain structures are formed adjacent the channel structure, wherein a liner material is disposed on at least a portion of the sidewalls of the source/drain structures. A nanowire spacer structure is formed between the first and second nanowires, wherein the nanowire spacer comprises an oxidized portion of the liner.
(FR) L'invention porte sur des procédés de formation de structures d'espaceurs de nanofils auto-alignés. Un mode de réalisation consiste à former une structure de canal comprenant un premier nanofil et un second nanofil. Des structures de source/drain sont formées adjacentes à la structure de canal, un matériau de revêtement étant disposé sur au moins une partie des parois latérales des structures de source/drain. Une structure d'espaceur de nanofils est formée entre les premier et second nanofils, l'espaceur de nanofils comprenant une partie oxydée du revêtement.
