Development of surface mount type "KP-2 dual wavelength photodiode KPMC29" for optical measurement with two wavelengths on the same optical axis Kyoto Semiconductor Co., Ltd. (President and CEO Tsuneo Takahashi, Head Office: Fushimi-ku, Kyoto) has developed the industry's smallest class photodiode, which has silicon and indium gallium arsenide photodiodes with sensitivity over a wide range of 400 to 1,700 nm arranged on the same optical axis. We have developed a surface mount type dual wavelength photodiode KPMC29 (KP-2 Two-tone PD hereafter). May 26, 2020 Kyoto Semiconductor Co., Ltd. Developed surface-mount type "KP-2 dual wavelength photodiode KPMC29" for optical measurement with two wavelengths on the same optical axis. Kyoto Semiconductor Co., Ltd. (President and CEO: Tsuneo Takahashi, Headquarters: Fushimi-ku, Kyoto), a leader in optical device solutions in manufacturing, has a silicon and indium gallium arsenide photodetector with a wide range of sensitivity from 400 to 1,700 nm. We have developed the industry's smallest class surface mount type KP-2 dual-wavelength photodiode KPMC29 (KP-2 Two-tone PD hereafter) in which are arranged on the same optical axis. With a wide sensitivity wavelength and a small package that achieves 1/8 the volume ratio of our conventional products, it is expected to be applied in the medical field where biological monitoring such as pulse oximeters is performed and in the healthcare field such as wearable activity meters. . In addition, since the photocurrent signals from the silicon and indium gallium arsenide light receiving elements can be extracted independently, it can be used for applications such as radiation thermometers that measure temperature without direct contact with high-temperature objects by measuring the photocurrent ratio. application becomes possible. Demand for spectroscopic analysis technology, which irradiates the object with light and identifies the physical properties and types of the object from the transmitted light and reflected light without direct contact, is increasing in a wide range of fields such as “medical,” “industrial,” and “security.” We are here. In spectroscopic analysis, it is important to have multiple light source wavelengths (multicolor) to cover various measurement items, and to have sensitivity in a wide wavelength range corresponding to the light source on the light receiving element side. In addition, for applications in medical devices and wearable digital devices that are expected to be worn on the human body, products that are smaller than conventional lead-type products are required. We have developed a product that can meet these demands. 1. Wide Sensitivity Wavelength (400~1,700nm) The wavelength range is widened by stacking on the same optical axis a silicon photodetector that is sensitive to short wavelengths and an indium gallium arsenide photodetector that is sensitive to long wavelengths. We succeeded. 2. In order to achieve the industry's smallest class compact surface-mount package, the KP-2 Two-tone PD has an indium gallium arsenide photodetector placed in a concave recess on the substrate side of the silicon photodetector through which light passes first. By storing , it is possible to reduce the height of the package as much as possible (patent pending, patent granted). As a result, the size has been reduced to 1/8 by volume compared to our conventional products.
