Samsung patents chip design with angled insulation to improve gate control
Samsung has filed a patent for a semiconductor structure that adds a sloped insulation layer between the gate electrode and the drain area of a transistor. This angled pattern sits alongside the main gate insulator to help manage electrical fields within the tiny switch.
In the filing’s own words
A semiconductor device includes: an active pattern on a substrate; a first source/drain pattern and a second source/drain pattern on the active pattern; a channel pattern between the first source/drain pattern and the second source/drain pattern; a gate electrode on at least a portion of side surfaces of the channel pattern and an upper surface of the channel pattern; a gate insulating layer between the channel pattern and the gate electrode; and a sloped insulation pattern between the second source/drain pattern and the gate electrode and inclined with respect to the channel pattern.
What exactly they claim (claim 1)
1. A semiconductor device comprising: an active pattern on a substrate; a first source/drain pattern and a second source/drain pattern on the active pattern; a channel pattern between the first source/drain pattern and the second source/drain pattern; a gate electrode on at least a portion of side surfaces of the channel pattern and an upper surface of the channel pattern; a gate insulating layer between the channel pattern and the gate electrode; and a sloped insulation pattern between the second source/drain pattern and the gate electrode and inclined with respect to the channel pattern.
