Title
(EN) SEMICONDUCTOR CONSTRUCTIONS WITH GATED ISOLATION REGIONS HAVING INDIUM-DOPED SUB-REGIONS
(FR) STRUCTURES SEMI-CONDUCTRICES
Abstract
(EN)
The invention includes a semiconductor construction wherein gate structures are separated by isolation regions that are provided with an indium-doped pocket and a covering gate. The invention also includes a semiconductor construction having a pair of channel regions that have sub-regions doped with indium and surrounded by boron. A pair of transistor constructions are located over the channel regions and are separated by an isolation region. The transistors have gates that are wider than the underlying sub-regions. The invention also includes a semiconductor construction that has transistor constructions with insulative spacers along gate sidewalls. Each transistor construction is between a pair source/drain regions that extend beneath the spacers. A source/drain extension extends the source/drain region farther beneath the transistor constructions on only one side of each of the transistor constructions. The invention also includes methods of forming semiconductor constructions.

La présente invention concerne une structure semi-conductrice comprenant une paire de zones de canal comportant des zones secondaires dopées à l'indium et entourées par du bore. Deux structures de transistor sont placées sur les zones de canal et sont séparées par une zone d'isolation. Les transistors comprennent des grilles qui sont plus larges que les zones secondaires sous-jacentes. Cette invention concerne également une structure semi-conductrice comprenant des structures de transistor comportant des séparations isolantes ainsi que des parois latérales de grille. Chacune des structures de transistor se trouve entre une paire de régions source/drain qui s'étend sous les séparations. Une extension source/drain prolonge la région source/drain sous les structures de transistor sur un côté seulement de chaque structure de transistor. Cette invention concerne également des procédés de formation de structures semi-conductrices.
