Title:

SEMICONDUCTOR DEVICE AND LIGHT EMITTING DEVICE PACKAGE COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2018/128419

Kind Code:

A1

Abstract:

An embodiment relates to a semiconductor device and a light emitting device package comprising the same. The semiconductor device according to the embodiment may comprise: a first semiconductor layer; a second semiconductor layer placed on the first semiconductor layer and including V-pits; an active layer placed on the second semiconductor layer; a third semiconductor layer placed on the active layer and having a wider band gap than the active layer; a fourth semiconductor layer placed on the third semiconductor layer and having a narrower band gap than the third semiconductor layer; and a fifth semiconductor layer placed on the fourth semiconductor layer and having a wider band gap than the fourth semiconductor layer, wherein the third semiconductor layer and the fifth semiconductor layer each contain aluminum as an ingredient, and the fifth semiconductor layer has a band gap equal to or wider than the third semiconductor layer. The semiconductor device according to the embodiment can improve the luminous efficiency by not only increasing the hole injection efficiency by the 2DHG effect, but also increasing injection of carriers that are injected through the V-pits.
