  • SEMICONDUCTOR DEVICE HAVING L-SHAPED CONDUCTIVE PATTERN
    Publication number: 20230326852
    Abstract: Disclosed herein is an apparatus that includes a semiconductor substrate having a main surface extending in a first direction and a second direction different from the first direction and a conductive pattern formed over the main surface of the semiconductor substrate. The conductive pattern includes a first section extending in the first direction, a second section extending in the second direction, and a third section connected between the first and second sections. The third section of the conductive pattern has a first slit extending in a third direction different from the first and second directions.
    Type: Application

  • Apparatuses and methods for semiconductor devices including clock signal lines
    Patent number: 11264068
    Abstract: Apparatuses for providing a clock signal for a semiconductor device are described. An example apparatus includes a chip including a first clock tree and a second clock tree. The first clock tree includes a first wiring segment extending in a first direction and a second wiring segment extending in a second direction perpendicular to the first direction and coupled the first wiring segment. The second clock tree includes a third wiring segment extending in the second direction, a fourth wiring segment extending in the first direction and coupled to the third wiring segment, and a fifth wiring segment extending in the second direction and coupled to the fourth wiring segment.
