Amkor is the first OSAT to deliver high volume manufacturing of products using AiP/AoP technology
Amkor’s cutting-edge AiP and AoP technology has already been deployed and offers fully-integrated5GNR millimeter wave (mmWave) and sub-6 GHz RF modules for smartphones and other mobile devices. These mmWave antenna modules deliver capabilities across several spectrum bands, in a very compact footprint that is well suited for integration in mobile devices.
To date, mmWave signals had not previously been used for mobile wireless communications due to many technical and implementation challenges, that impact nearly every facet of device engineering, including materials, form-factor, industrial design, thermal performance and regulatory requirements for radiated power. Successful implementation of these types of antenna solutions, spanning both mmWave and sub-6 spectrum bands for 5G, will transform the mobile industry and consumer experience.
Why AiP/AoP? What are the Benefits to Smartphones?
AiP/AoP improves 5G signal integrity and overcomes the challenges below, using small footprint-phased antenna array design and minimizing the space required to support mmWave inside 5G devices.
Technical Challenges Addressed by AiP/AoP
- Propagation:High mmWave frequencies experience higher path loss and attenuation, so signals don’t travel very far
- Range:mmWave signals are easily blocked by objects
- Size:mmWave typically requires an array of antenna elements to help overcome these issues, thereby increasing the footprint inside a device
Key Amkor Packaging Technologies for AiP/AoP
- Products in HVM that support frequency bands above 26 GHz
- Compartmental shielding using laser trench and paste filling technology
- Partial (selective) conformal shielding

- Substrate layer counts: up to 14 layers
- Thin-film RDL and dielectrics for 77 GHz and above
5G Market Challenges:
- Introduction of mmWave frequencies
- Higher demands on power consumption
- Extended RF component counts
除了广泛的包(Si系统P) capacity and AiP/AoP technology, Amkor has developed an extensive toolset to maximize circuit density and address the sophisticated packaging formats required to productize 5G applications – such as double-sided assembly, embedded die in substrate, thin-film RDL & dielectrics, and various types of RF shielding. This toolset, combined with expertise in RF and antenna package design, uniquely positions Amkor to serve customers who want to outsource the challenges and high investment associated with combining multiple ICs with advanced package assembly and test technologies for 5G networks.
As demand for packages that support 5G starts to ramp up, Amkor is already well underway with the successful implementation of AiP/AoP technology.
