Microelectronics and nanoelectronics are subfields of electronics in which the nominal feature sizes of electronic components are between 100 and 0.1 micrometers in magnitude (microelectronics) or 100 nanometers or smaller (nanoelectronics). The memory storage power of today’s advanced electronic devices has been achieved by significantly increasing the density of microchips. By decreasing the size of field-effect transistors, more components can be fit into integrated circuits, allowing for more powerful and energy-efficient electronic devices with reduced weights and power consumption. * * * ## Related Products Slide 1 of 32 1 of 8 [![Chloroplatinic acid hydrate 99.995% trace metals

Since this was projected in 1965, semiconductor fabrication technology sustained this rate of advancement and revolutionized the industry. However, pace of dimension reduction is slowing, and the key challenge in fabricating electronic components in the sub-micrometer range is the design of the transistor gate, which controls the current flow in the channel. The smaller electronic components are, the more challenging they become to manufacture. Physical and quantum effects alter materials’ properties from a macroscale to a nanoscale, influencing inter-atomic interactions and quantum mechanical properties. The arrival of innovative materials, carbon nanotubes, boron nitride nanotubes, quantum dots, and graphene additives, have advanced the minimization of nanotechnology and microtechnology. These and other new materials can be shaped and manipulated with extraordinary precision at the tiniest of scales. Novel technologies enable the deposition and layering of electronic materials with precise thickness, even down to the atomic level. Thin-film semiconductor device fabrication technology uses conducting, semiconducting, and insulating materials to deliver advanced capabilities at high volumes and very low cost. Modern manufacturing methods for nanoelectronics include patterning (lithography), etching, thin film deposition, and doping techniques. Emerging research fields focus on new approaches in nanotechnology and quantum mechanical effects. Molecular electronics uses single molecules as electronic components to establish electrical contact with bulk-sized electrodes. Spintronics, or spin-transport electronics, manipulates electrons’ spin property with magnetic and electric fields, resulting in a spin-polarized current that provides higher data transfer speeds and greater storage capacity, memory density and processing power than is possible with electric charge alone.
