Title: Naohito Yanagida: Innovator in Memory Technology
Introduction
Naohito Yanagida is a prominent inventor based in Yokkaichi, Japan. He has made significant contributions to the field of memory technology, holding a total of 5 patents. His work focuses on enhancing the performance and efficiency of memory devices, particularly in the realm of resistive random access memory.
Latest Patents
One of Yanagida's latest patents is titled "Concave word line and convex interlayer dielectric for protecting a read/write layer." This invention involves the formation of an alternating stack of electrically conductive and insulating layers over global bit lines on a substrate. The stack is patterned to create a line stack of conductive and insulating lines. Trench isolation structures are defined within each trench to establish multiple memory openings, which are laterally spaced by the line stack and trench isolation structures. The conductive lines are recessed relative to the insulating lines, allowing for the deposition of a read/write memory material in the recesses. This material is then anisotropically etched to expose the top surface of a global bit line at the bottom of each memory opening. An electrically conductive bit line is formed within each memory opening, culminating in the creation of a resistive random access memory device.
