Special Issue Information
Dear Colleagues,
With the rapid development of electronic information technologies, such as high-frequency communication, artificial intelligence, and cloud computing, various types of low-k materials have been adopted to avoid the signal capacitance delay, crosstalk, and increased power consumption caused by metal resistance and parasitic capacitance between lines and layers. For example, organosilicates (fluorinated silicon glass (FSG or SiOF) and organosilicate glass (SiCOH), etc.) have been widely used for low-k interlayer dielectrics in integrated circuits (IC) packaging. Additionally, certain kinds of polymers (such as poly(arylene ether), polyimide, parylene-N/F, polytetrafluoroethylene, benzocyclobutene-based polymer, etc.) are commercially available for spin-on dielectric applications.
Aside from material innovations, advanced chemical and physical structures of organic, inorganic, and hybrid low-k materials should be proposed to meet operation requirements, including outstanding mechanical property, good thermal stability, low shrinkage rate, low expansion coefficient, low water absorption, and good processability and surface smoothness.
The aim of this Special Issue is to elaborate on the recent innovations of functional low-k materials (including organic, inorganic, and organic/inorganic hybrid systems) and understand the relationship between structure and overall performances (such as dielectric, mechanical, thermal stability and other properties).
A thorough study of their chemical structures and compositions, microscopic properties on nano, micro, meso-scales, and different fabrication methods will greatly guide the future design and preparation of next-generation low-k functional materials to adapt to the fast demand of modern electronic components in high-frequency transmission.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
