Title: Shiori Kataoka: Innovator in Memory Device Technology

Introduction

Shiori Kataoka is a prominent inventor based in Yokkaichi, Japan. She has made significant contributions to the field of memory device technology, holding a total of 2 patents. Her innovative work focuses on enhancing the performance and efficiency of memory devices.

Latest Patents

Kataoka's latest patents include a "Three-dimensional memory device containing replacement contact via structures and method of making the same." This invention involves forming an alternating stack of insulating layers and sacrificial material layers with stepped surfaces. Sacrificial metal plates are created on the top surfaces of the sacrificial material layers, and a retro-stepped dielectric material portion is formed over these plates. The process includes forming contact via cavities through the dielectric material using the sacrificial metal plates as etch stop structures. The sacrificial metal plates are then replaced with insulating spacer layers, and the remaining volumes are filled with electrically conductive layers.

Another notable patent is the "Resistive random access memory device containing discrete memory material portions and method of making thereof." This invention describes the formation of an alternating stack of insulating layers and electrically conductive layers over a substrate. The sidewalls of the conductive layers are laterally recessed to create regions for a conformal barrier material layer. An amorphous precursor memory material layer is deposited, followed by an anneal process that selectively crystallizes portions of this layer into discrete self-aligned crystalline memory material portions.
