INFRARED SENSOR IC, INFRARED SENSOR AND METHOD FOR PRODUCING SAME

摘要

An extremely small infrared sensor IC is disclosed which is hardly affected by electromagnetic noises or thermal noises. Also disclosed are an infrared sensor and a method for producing the same. A small-sized infrared sensor IC in a simple package which can be operated at room temperature can be realized by hybridizing a compound semiconductor sensor unit (2) and an integrated circuit unit (3) in a same package. The compound semiconductor sensor unit (2) is composed of a compound semiconductor with low device resistance and high electron mobility, and the integrated circuit unit (3) performs an operation by processing electrical signals from the compound semiconductor sensor unit (2).
