Title:
CIRCUIT STRUCTURE AND METHOD FOR FORMING SAME, AND MEMORY
Document Type and Number:
WIPO Patent Application WO/2024/060332
Kind Code:
A1
Abstract:
A circuit structure and a method for forming same, and a memory. The circuit structure comprises a first layer-changing assembly (1), a second layer-changing assembly (2), and a coupling pad (3). The first layer-changing assembly (1) comprises a first layer-changing portion, a first pad (12), and a second pad (13), the first layer-changing portion comprises a first layer-changing via, and the first pad (12) and the second pad (13) are respectively connected to two ends of the first layer-changing via. The second layer-changing assembly (2) comprises a second layer-changing portion, a third pad (22), and a fourth pad (23), the second layer-changing portion comprises a second layer-changing via, the third pad (22) and the fourth pad (23) are respectively connected to two ends of the second layer-changing via, and the second layer-changing via is parallel to the first layer-changing via. The coupling pad (3) comprises a first coupling pad (31), the first coupling pad (31) comprises a first inner via (311) and a second inner via (312), the first inner via (311) is communicated with the second inner via (312) by means of a first connecting channel (313), the second layer-changing via penetrates through the first inner via (311), and the first layer-changing via penetrates through the second inner via (312). The circuit structure can reduce far-end crosstalk and reduce the possibility of signal distortion.
