Publication number: 20240071923Abstract: A semiconductor device may include lower metal wirings on a substrate, a first upper insulating interlayer on the lower metal wirings, a first upper wiring including a first upper via in the first upper insulating interlayer and a first upper metal pattern on the first upper insulating interlayer. The semiconductor device may also include a second upper insulating interlayer on the first upper insulating interlayer, an uppermost wiring including an uppermost via in the second upper insulating interlayer, an uppermost metal pattern on the second upper insulating interlayer, and an oxide layer for supplying hydrogen on the second upper insulating interlayer. The lower metal wirings may be stacked in a plurality of layers. The oxide layer for supplying hydrogen may cover the uppermost wiring. A thickness of the uppermost via may be less than 40% of a thickness of the uppermost metal pattern.Type: ApplicationFiled: June 14, 2023Publication date: February 29, 2024Inventors: Minjun SONG, Jongmin LEE, Joongwon SHIN, Nara LEE, Jimin CHOI
