Publication number: 20240105644Abstract: A semiconductor die package includes a high dielectric constant (high-k) dielectric layer over a device region of a first semiconductor die that is bonded with a second semiconductor die in a wafer on wafer (WoW) configuration. A through silicon via (TSV) structure may be formed through the device region. The high-k dielectric layer has an intrinsic negative charge polarity that provides a coupling voltage to modify the electric potential in the device region. In particular, the electron carriers in high-k dielectric layer attracts hole charge carriers in device region, which suppresses trap-assist tunnels that result from surface defects formed during etching of the recess for the TSV structure. Accordingly, the high-k dielectric layer described herein reduces the likelihood of (and/or the magnitude of) current leakage in semiconductor devices that are included in the device region of the first semiconductor die.Type: ApplicationFiled: January 6, 2023Publication date: March 28, 2024Inventors: Tsung-Hao YEH, Chien Hung LIU, Hsien Jung CHEN, Hsin Heng WANG, Kuo-Ching HUANG
