SCR (SILICON CONTROLLED RECTIFIER) |
A silicon device with four layers (PNPN) having an input control terminal (gate), an output terminal (anode) and a terminal common to both input and output (cathode). It generally operates as an AC switch for lighting and heating control. |

SINE WAVE |
A smooth, continuously moving waveshape that has no break in its appearance. It has positive and negative half-cycles that are generally symmetrical with respect to a reference. The cyclical repetition of these waves produces a waveshape that has a specified frequency in hertz (number of cycles per second) and a specified amplitude. |

SLURRY |
A thick mixture of water and fine wafer particles produced during the wafer sawing process. If wafer is not cleaned properly, slurry can be seen as a very fine particle deposit over the surface of individual die, sometimes forming patterns from the spray of the mixture. |

SQUARE WAVE |
A rectangular-shaped (step-function) periodic wave with a positive and negative half-cycle of equal lengths of time or duration. A square wave consists of a sine wave's fundamental frequency combined with the odd harmonics (multiples) of its fundamental frequency. |

STABILITY |
The ability of a component, circuit, or system to maintain a fixed level of operation within specified tolerances under varying external conditions. Changing conditions include voltage, frequency, temperature, and longevity. See RELIABILITY. |
