Transistors having features which preclude straight-line lateral conductive paths from a channel region to a source/drain region

摘要

Some embodiments include transistors having a channel region under a gate, having a source/drain region laterally spaced from the channel region by an active region, and having one or more dielectric features extending through the active region in a configuration which precludes any straight-line lateral conductive path from the channel region to the source/drain region. The dielectric features may be spaced-apart islands in some configurations. The dielectric features may be multi-branched interlocking structures in some configurations.

1. A transistor comprising:
a channel region under a gate; a source/drain region laterally spaced from the channel region by an active region; one or more dielectric features extending through the active region in a configuration which precludes any straight-line lateral conductive path from the channel region to the source/drain region; and wherein the dielectric features are configured as spaced-apart interlocking structures.
