In gate stack engineering for semiconductor devices, one of the key challenges is the scaling of the gate dielectric material. As device dimensions shrink, the gate dielectric thickness needs to be reduced to maintain adequate gate control over the channel. However, this leads to increased leakage currents and reliability issues due to the quantum mechanical tunneling effects that become significant at such small thicknesses. Finding alternative high-k dielectric materials with superior electrical properties and compatibility with the manufacturing process is an ongoing challenge.
We’ve curated applications and patents from the semiconductor industry over the past three years. Following an auto-landscape analysis, we’ve distilled the following insights.
Because of the lag in time between patent filing and publication of the related application (onaverage 18 months), this report does not give a complete picture but rather a perspective on
publicly available semiconductor-related patent information up until February 2024.
Summary
The collaboration between Beijing Superstring Academy of Memory Technology and Changxin Memory Technologies could be due to the increasing demand for advanced memory technologies and the need for research institutions to collaborate with semiconductor companies to develop cutting-edge solutions.
