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; metal oxide patterns formed on the metal oxide layer; a catalytic pattern formed over the substrate disposed between the metal oxide patterns; and a protective layer formed over the metal oxide pattern and the catalytic pattern, wherein a cavil is formed between an upper portion of the catalytic pattern and the protective layer. 2. The hydrogen sensor according to claim 1 , wherein the catalytic pattern is formed at a bottom of the metal oxide patterns or is formed along a sidewall and bottom of the metal oxide patterns. 3. 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.
