Microelectronic Materials

[Kimbery Challacombe]

Thispractical book shows how an understanding of structure, thermodynamics, and electrical properties can explain some of the choices of materials used in microelectronics, and can assist in the design of new materials for specific applications. It emphasizes the importance of the phase chemistry of semiconductor and metal systems for ensuring the long-term stability of new devices. The book discusses single-crystal and polycrystalline silicon, aluminium- and gold-based metallisation schemes, packaging semiconductor devices, failure analysis, and the suitability of various materials for optoelectronic devices and solar cells. It has been designed for senior undergraduates, graduates, and researchers in physics, electronic engineering, and materials science.

Three-dimensional (3D) structures capable of reversible transformations in their geometrical layouts have important applications across a broad range of areas. Most morphable 3D systems rely on concepts inspired by origami/kirigami or techniques of 3D printing with responsive materials. The development of schemes that can simultaneously apply across a wide range of size scales and with classes of advanced materials found in state-of-the-art microsystem technologies remains challenging. Here, we introduce a set of concepts for morphable 3D mesostructures in diverse materials and fully formed planar devices spanning length scales from micrometres to millimetres. The approaches rely on elastomer platforms deformed in different time sequences to elastically alter the 3D geometries of supported mesostructures via nonlinear mechanical buckling. Over 20 examples have been experimentally and theoretically investigated, including mesostructures that can be reshaped between different geometries as well as those that can morph into three or more distinct states. An adaptive radiofrequency circuit and a concealable electromagnetic device provide examples of functionally reconfigurable microelectronic devices.

Uncover the Defects that Compromise Performance and ReliabilityAs microelectronics features and devices become smaller and more complex, it is critical that engineers and technologists completely understand how components can be damaged during the increasingly complicated fabrication processes required to produce them.A comprehensive survey of defe

The nanoscale properties of materials and material systems determine the macroscale performance and reliability of components, functions and processes. Novel and complex material (systems) are therefore a key for innovations in micro-, nano- and optoelectronics, energy, environmental and medical (technology).

Having the right knowledge about the relevant structure-property relationships can accelerate the development of new products, specifically improve the reliability of components and increase the efficiency of technological processes. This requires a deep understanding of materials and their time-resolved interactions from the atomic to the millimeter scale.

The low power consumption and electronic properties of integrated circuits depend on the purity of the wafer, which itself undergoes complex manufacturing processes before it is shipped to chip production.

Air impurities that change the electrical properties of the substrate must not get onto the wafers during the manufacturing process. The process steps must be protected from trace substances from building materials and undesirable influences from entrained reaction gases.

artemis control has developed concepts and products for the measurement and prevention of trace substances. We support our customers permanently in the environment of increasing requirements. This applies to new plants as well as to the improvement of existing process plants.

Microelectronics is a subfield of electronics. As the name suggests, microelectronics relates to the study and manufacture (or microfabrication) of very small electronic designs and components. Usually, but not always, this means micrometre-scale or smaller. These devices are typically made from semiconductor materials. Many components of a normal electronic design are available in a microelectronic equivalent. These include transistors, capacitors, inductors, resistors, diodes and (naturally) insulators and conductors can all be found in microelectronic devices. Unique wiring techniques such as wire bonding are also often used in microelectronics because of the unusually small size of the components, leads and pads. This technique requires specialized equipment and is expensive.
