Abstract
Official abstract text for this publication.
A hydrogen sensor and a method for manufacturing the same are provided. The hydrogen sensor includes a metal oxide layer formed over a substrate, and a catalytic pattern that is formed over the metal oxide layer. Further, a protective layer is formed over the catalytic pattern.
First claim
Opening claim text (preview).
What is claimed is: 1. A hydrogen sensor, comprising: a substrate; a metal oxide layer formed over the substrate; a catalytic pattern formed over the metal oxide layer; a protective layer formed over the metal oxide layer and the catalytic pattern; a second recess formed over an upper surface of the metal oxide layer; and wherein the catalytic pattern is disposed within the second recess. 2. The hydrogen sensor according to claim 1 , further comprising: at least one first recess formed at an upper portion of the metal oxide layer among the catalytic patterns. 3. The hydrogen sensor according to claim 1 , wherein a top surface of the metal oxide layer is formed in a substantially embossed shape. 4. The hydrogen sensor according to claim 3 , wherein the catalytic pattern is disposed at a lower portion among the substantially embossed metal oxide layers. 5. The hydrogen sensor according to claim 1 , wherein: the metal oxide layer includes one selected from the group consisting of: vanadium, niobium, tantalum, chromium, molybdenum, and tungsten, and the catalytic pattern includes at least one selected from the group consisting of: palladium, iridium, ruthenium, platinum, rhodium, gold, and silver.
