  4. Shallow trench isolation - Wikipedia

    en.wikipedia.org/wiki/Shallow_trench_isolation

    The key steps of the STI process involve etching a pattern of trenches in the silicon, depositing one or more dielectric materials (such as silicon dioxide) to fill the trenches, and removing the excess dielectric using a technique such as chemical-mechanical planarization. [2]

Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.

  8. Dielectric strength - Wikipedia

    en.wikipedia.org/wiki/Dielectric_strength

    In physics, the term dielectric strength has the following meanings: for a pure electrically insulating material, the maximum electric field that the material can withstand under ideal conditions without undergoing electrical breakdown and becoming electrically conductive (i.e. without failure of its insulating properties).

  9. Gate oxide - Wikipedia

    en.wikipedia.org/wiki/Gate_oxide

    Gate oxide at NPNP transistor made by Frosch and Derrick, 1957 [1]. The gate oxide is the dielectric layer that separates the gate terminal of a MOSFET (metal–oxide–semiconductor field-effect transistor) from the underlying source and drain terminals as well as the conductive channel that connects source and drain when the transistor is turned on.
