Polyimide is one of the most efficient polymers in many industries for its excellent thermal, electrical, mechanical, and chemical properties as well as its easy processability. In the electronic and electrical engineering industries, polyimide has widely been used for decades thanks to its very good dielectric and insulating properties at the high electric field and at high temperatures of around 200°C in long term-service. Moreover, polyimide appears essential for the development of new electronic devices where further considerations such as high power density, integration, higher temperature, thermal conduction management, energy storage, reliability, or flexibility are required in order to sustain the growing global electrical energy consumption. This book gathers interdisciplinary chapters on polyimide in various topics through state-of-the-art and original ongoing research.

Polyimides are nowadays quite famous dielectrics and insulating materials widely used in electronics and electrical engineering applications from low voltage microelectronics up to high voltage engineering industry. They are well appreciated because of their excellent physical properties (i.e., thermal, electrical, and mechanical properties), as well as, their coating process ease either from a liquid or a gas phase. Consequently, polyimides appear in a various range of applications to efficiently separate metal levels or electrodes at different electrical potentials. This chapter intends to review the main chemical generalities of polyimides, the different monomer families, the coating and curing processes, and the main physical properties for electronic and high voltage industrial applications.

This is the first book to provide an in-depth presentation of photosensitive polyimides for electronic and photonic applications. The authors are leading specialists in this field from Japan, Europe and the U.S. From the Preface Aromatic polyimides were developed originally as thermostable flexible polymer films for space applications. Now polyimides have found widespread use in the manufacture of electronic devices and have been employed in increasingly diverse areas of electronics and information technology. In addition to their excellent thermal stability and high processability, a wide range of chemical and physical properties provided by molecular engineering makes polyimides highly versatile in the electronics and information industries. Lithography of polyimides is an inevitable process in using polyimides for microelectronic fields, and hence increasing research has been devoted to developing photosensitive polyimides, which make it unnecessary to use photoresists for patterning polyimides and diminishing markedly the number of steps in fabrication of various electronic devices. In addition, the development of technology of photosensitive polyimides is expected to play a great role in manufacturing photonic devices in the near future, when the design and control of hyper fine structures . . . including higher thermal stability and better processability would be essential.

Polyimide is an organic polymer that exhibits the highest level of heat resistance, exhibits excellent mechanical properties and electrical insulation, and is stable for a long period of time. In addition, since it is easy to obtain polymers with different physical characteristics by changing the combination of monomers, it is possible to obtain the desired properties according to the application, and it is used in a wide range of fields such as insulating protective films for semiconductors and electronic components. This chapter describes polyimides used in microelectronics applications such as semiconductors, electronic components, displays, image sensors, and lithium-ion secondary batteries. The development of practical aspects such as photosensitivity, low-temperature curability, and adhesion to copper when used in microelectronics will be described.
