PDC 1 - Robust Electronics for Autonomous Driving
- Electronics Packages for External Sensing and e-Drive
- Robustness Validation of Automotive Electronics
- Damage Mechanism in Automotive Electronics
The amount of electronics in vehicles has increased dramatically over the last years and will increase further in the future. Autonomous driving demands highly robust surround-sensing of the entire car for adaptive cruise control, traffic sign recognition, pedestrian detection, drowsiness detection, collision mitigation, blind spot detection, cross-traffic alert, parking assist and lane departure prevention, using a combination of many technologies that include:
- Video cameras (mono, stereo cameras; infrared cameras for night vision),
- RADAR (long and short range radars)
- LIDAR (light detecting and ranging by laser light) and
- Ultrasound sensors.
The demand for alternative, more energy-efficient forms of mobility stimulates the application of electro mobility. Electric vehicles require efficient and lighter components such as electric motors, inverters, converters, control and driver electronics and high-voltage batteries.
Electronics modules integrated in sensors and actuators facing harsh environment and higher temperatures. Smaller packages and higher integration levels are needed through embedded systems in package, multi-die packages and finer pitch packages. New packaging technologies have to be qualified for the reliability and safety automotive standards.
E-mobility increases the today's life time requirements of automotive electronics. Additional to the driving time the charging operations have to be considered. To meet this new life time requirements the qualification of electronics module is changing from the detection of defects to the study of the failure mechanisms. The robustness validation is an approach to qualification and validation based on failure mechanisms relates to specific mission profiles. Fraunhofer IMWS is a long term partner of automotive industry in failure analysis and mechanical testing and modeling. The special high resolution analysis tools and their performance will be introduced. Based on broad practical experience along complete supply chain examples of robustness validation will be demonstrated.

PDC 2 - Introduction into Photonic Packaging and Interconnection technology
The photonic Packaging and Interconnection technology (PAVT) is the interface between the optical communications engineering and classical electrical connection technology and microsystem technology. The techniques such as bonding, adhesive bonding, soldering, thick film / thin film technology and the multi-layer printed circuit board technology also be used to build up of an optoelectronic device (OEIC), such as some techniques of microsystems technology such as etching of silicon substrates or masks and coating techniques. The application of the OEICs in the communication system determines the system structure of the package that needs to be very cost effective in extreme cases, e.g. to be used in future optical Ethernet connections. This can be very expensive and time-consuming, if only some specific functions are used in a wide-area range, as has already been explained in the previous chapter to the optical transmission systems.
For clarity and definition of the roles of the photonic assembly and interconnection technology (PAVT) a proper definition is to be introduced at this point:
"The photonic assembly and interconnection technology is used to connect optical and electrical transmission media and electrical supply lines to photonic devices in a stable, environmentally adapted housing."
To develop an OEIC Packaging many different techniques are necessaryto be mentioned:
- High Frequency Technology
- Classical Optics / Wave Optics
- Precision engineering design and CAD design
- Refrigeration / heat management
- Communications Engineering
- Solid State Physics
- Etching of silicon substrates
- Mask techniques
- Thick film / thin film technology
- Gluing, soldering, welding, bonding technology
In this course the fiber chip coupling technology will be analyzed, while new coupling techniques and cost optimization basics are presented. Thus, at the beginning an overview of the technology drivers of optical communications systems will be discussed. Further on many examples of photonic packaging and interconnection technology are presented in depth. All actual adjustment and fixation techniques are focused.
A deeper analysis of the optical interconnection technology with basic theory of waveguide coupling and loss mechanisms concludes the introductory part of the course. Then, an overview on the modular technology of major photonic components in the field of high-rate fiber-optic networks will be presented, followed by the analysis of the fiber-chip coupling in these different applications. In the conclusions a summary and an outlook on the further development of the technology of photonic packaging and interconnection technology will be given.

PDC 4 - From Wafer to Panel Level Packaging
Panel Level Packaging (PLP) is one of the latest trends in microelectronics packing. Besides technology developments towards heterogeneous integration including multiple die packaging, passive component integration in package and redistribution layer or package-on-package approaches also larger substrates formats are targeted. Manufacturing is currently done on wafer level up to 12”/300 mm and 330 mm respectively. For higher productivity and therewith lower costs larger form factors are introduced. Instead of following the wafer level roadmaps to 450 mm, panel level packaging might be the next big step. Sizes considered for the panel range from 300x300 mm² to 457x610 mm³ or 510x515 mm² up to 600x600 mm² or even larger. Additionally PLP has the opportunity to adapt processes, materials and equipment from other technology areas. Printed Circuit Board (PCB), Liquid Crystal Display (LCD) or solar equipment is manufactured on panel sizes and offer new approaches also for Fan-out Panel Level Packaging (FOPLP).
However, an easy upscaling of technology when moving from wafer to panel level is not possible. Materials, equipment and processes have to be further developed or at least adapted. A view along the process chain offers lots of possibilities but also challenges. Starting from carrier material selection for a chip first approach where not only the thermo-mechanical behavior but also properties as e.g. weight or stability should be considered. Pick and place assembly on carrier is independent from wafer or panel formats a bottleneck. Here new equipment or even new approaches for high speed but also high accuracy assembly are required. Compression molding is typically used for chip embedding and to form the reconfigured wafer or panel. Liquid, granular and sheet type molding compounds are available. All allowing chip embedding with pros and cons in cost, processability but also in cleanroom compatibility. For redistribution layer (RDL) formation a large variety of lithography tools and dielectric material options exist. As dielectrics photosensitive as well as non-photosensitive or liquid versus dry-film materials can be considered. Mask-based lithography as e.g. stepper technology is just as maskless based tools as laser direct imaging (LDI) available for panel sizes. Both offering different capabilities and strategies to overcome challenges from die placement accuracy and die shift after molding. Finally also solutions for grinding, balling and singulation are needed. Handling and especially automated handling of molded large panels including also storage and transport is still an open topic as until now only custom-made solutions exist.
The PDC will give a status of the current Fan-in and Fan-out Wafer Level Packaging as well Panel Level Packaging. This will include material discussion, technologies, applications and market trends as well as cost modelling.
