Technology for high power devices has made impressive progress in increasing the current density of power semiconductor, system module, and design optimization, which realize high power systems with heterogeneous functional integration. Depending on the performance development of high power semiconductor, packaging technology of high power device is urgently required for efficiency improvement of the device. Power device packaging must provide superior thermal management due to high operating temperature of power modules. Here we, therefore, review critical challenges of typical power electronics packaging today including core assembly processes, component materials, and reliability evaluation regulations.

Advanced packaging is emerging as a core technology owing to the increasing demand for multifunctional and highly integrated semiconductors to achieve low power and high performance following digital transformation. It may allow to overcome current limitations of semiconductor process miniaturization and enables single packaging of individual devices. The introduction of advanced packaging facilitates the integration of various chips into one device, and it is emerging as a competitive edge in the industry with high added value, possibly replacing traditional packaging that focuses on electrical connections and the protection of semiconductor devices.

전기자동차용 전력반도체 패키징 기술에 대한 분석을 수행하였다. 비정형 데이터인 특허들을 수집하여 유효특허를 도출하여 LDA 기법을 적용한 토픽모델링을 수행하였다. 20개의 토픽으로 분류하였고 각 토픽별 추출된 단어를 통해 기술에 대한 정의를 내렸다. 각 토픽의 대한 동향분석을 위해 연도별 빈도수에 대한 회귀분석을 통해 토픽별 Hot토픽과 Cold 토픽을 도출하여 전력반도체 패키징 기술의 동향을 분석하였다. Hot 토픽의 기술로는 내전압에 따른 패키지 구조 기술과 입출력 관련 제어 기술, 방열기술을 도출하였고 Cold 토픽 기술로는 인덕턴스 저감기술이 도출되었다.

LED (Light Emitting Diode) lighting is gaining more and more market penetration as one of the global warming countermeasures. LED is the next generation of fusion source composed of epi/chip/packaging of semiconductor process technology and optical/information/communication technology. LED has been applied to the existing industry areas, for example, automobiles, TVs, smartphones, laptops, refrigerators and street lamps. Therefore, LED makers have been striving to achieve the leading position in the global competition through development of core source technologies even before the promotion and adoption of LED technology as the next generation growth engine with eco-friendly characteristics. However, there has been a point of view on the cost compared to conventional lighting as a large obstacle to market penetration of LED. Therefore, companies are developing a Chip-Scale Packaging (CSP) LED technology to improve performance and reduce manufacturing costs. In this study, we perform patent analysis associated with Flip-Chip CSP LED and flow chart for promising technology forecasting. Based on our analysis, we select key patents and key patent players to derive the business strategy for the business success of Flip-Chip CSP PKG LED products.

Recently, a demand in sustainable green technologies is requiring the lead free bonding for high power module packaging due to the environmental pollution. The Transient-liquid phase (TLP) bonding can be a good alternative to a high Pb-bearing soldering. Basically, TLP bonding is known as the combination of soldering and diffusion bonding. Since the low melting temperature material is fully consumed after TLP bonding, the remelting temperature of joint layer becomes higher than the operating temperature of the power module. Also, TLP bonding is cost-effective process than metal nanopaste bonding such as Ag. In this paper, various TLP bonding techniques for power semiconductor were described.
