Abstract

Polymer-derived ceramics (PDCs) offer a variety of unique features that outperform classical powder-sintered ceramics and make PDCs valuable candidates for challenging applications such as implantable MEMS. The precise controllability of the precursors’ chemical composition allows the adjustment of the functional properties such as the electrical conductivity. Well known PDC systems are being customized and shaped in way not being possible before by a sophisticated combination of various advanced microfabrication techniques such as photolithography, 2PP 3D printing, and thermal scanning probe lithography. Continuing the research of a former CTI & SNSF project and resorting to a comprehensive study of the curing and pyrolysis processes of polysilazanes, the current collaborative project Ceramic X.0 targets the fabrication and evaluation of novel ceramics with unique properties and advanced shapes.

Chemical composition

A chemical composition specifies the identity, arrangement, and ratio of the chemical elements making up a compound by way of chemical and atomic bonds. Chemical formulas can be used to describe the relative amounts of elements present in a compound. For example, the chemical formula for water is H2O: this means that each molecule of water is constituted by 2 atoms of hydrogen (H) and 1 atom of oxygen (O). The chemical composition of water may be interpreted as a 2:1 ratio of hydrogen atoms to oxygen atoms.

MEMS

MEMS (Microelectromechanical systems) is the technology of microscopic devices incorporating both electronic and moving parts. MEMS are made up of components between 1 and 100 micrometres in size (i.e., 0.001 to 0.1 mm), and MEMS devices generally range in size from 20 micrometres to a millimetre (i.e., 0.02 to 1.0 mm), although components arranged in arrays (e.g., digital micromirror devices) can be more than 1000 mm2.

Chemical substance

A chemical substance is a form of matter having constant chemical composition and characteristic properties. Chemical substances can be simple substances (substances consisting of a single chemical element), chemical compounds, or alloys. Chemical substances that cannot be separated into their simpler constituent elements by physical means are said to be 'pure'; this notion intended to set them apart from mixtures.
