Integrated circuit construction

OFETs constructed on a silicon wafer do not lake advantage of one of the main interest of organic materials, namely the possibility of building electronic devices on plastic substrates. A second important drawback of the silicon-based structure is the difficulty to individually address the gale of transistors built on the same wafer, which would prevent the achievement of integrated circuits. 

A final comment on the Czochralski Method GaAs has become important in construction of integrated circuits for computers because of the promise of speed of response and density of components, compared to silicon wafers. Both As and Ga tend to oxidize in air as they approach the melt stage and AS2O3 sublimes. Both elements are toxic to man. In the... 

With electron microscopes providing the eyes, researchers explore the nanoworld. Miniaturization of electronics has reached the point where components of an integrated circuit can be as small as 0.000002 inches (50 nm), well within the scale of nanotechnology. Even more ambitious developments are on the drawing board or in the laboratory. As described below, some researchers are hoping to use atoms as building blocks to construct motors on a vanishingly small scale. 

The circuit may be easily constructed for a modest cost using inexpensive operational amplifiers and any of a number of integrated circuit oscillators that are commercially available. This basic piece of instrumentation is suitable for student laboratory experiments, conductometric monitoring of distilled water or...

To fabricate the integrated circuit (IC), layers with various electrical properties must be introduced into or deposited onto the substrate. These layers may consist of insulating, semiconducting, and conducting films. The construction of the layers in only the desired areas relies on a series of patterning steps which is briefly illustrated in Figure 1. Light sensitive...

Abstract. The constructive and technological features of silicon electrodes of polymer electrolyte membrane fuel cell (PEMFC) are discussed. Electrodes are made with application of modem technologies of integrated circuits, and technologies of macroporous silicon. Also ways of realization of additional functionalities of electrodes to offered constructive - technological performance are considered. 

The rapid development of solid-state electronic devices in the last two decades has had a profound effect on measurement capabilities in chemistry and other scientific fields. In this chapter we consider some of the physical aspects of the construction and function of electronic components such as resistors, capacitors, inductors, diodes, and transistors. The integration of these into small operational amplifier circuits is discussed, and various measurement applications are described. The use of these circuit elements in analog-to-digital converters and digital multimeters is emphasized in this chapter, but modern integrated circuits (ICs) have also greatly improved the capabilities of oscilloscopes, frequency counters, and other electronic instruments discussed in Chapter XIX. Finally, the use of potentiometers and bridge circuits, employed in a number of experiments in this text, is covered in the present chapter.

DIP (Dual Inline Package) A standard housing constructed of hard plastic commonly used to hold an integrated circuit. The circuit s leads are connected to two parallel rows of pins designed to fit snugly into a socket these pins may also be soldered directly to a printed-circuit board. If you try to install or remove dual inline packages, be careful not to bend or damage their pins.
