polyimide

1 8.4
A strong plastic that resists heat and chemicals and is used in electronics
  • noun
  • /ˌpɒliˈaɪmɪd/
  • Specialized
: poliimida
  • A thick layer is used to enhance the photoresist and polyimide adhesion.
  • polyimide adhesion
  • polyimide layer
  • polyimide dielectric

Examples

  • The critical wiring, which consists of five levels of copper lines with a polyimide dielectric, is deposited on top of this base.

    Academic text (1998)
  • The Cu layer is then planarized to the polyimide surface using a proprietary procedure.

    Academic text (1998)
  • The depth of the affected areas could be as much as half of the polyimide thickness.

    Academic text (1998)
  • The topography in the polyimide above the metal features was removed in the initial stages of polishing.

    Academic text (1998)
  • The first polyimide layer, one of whose functions is to planarize the substrate surface, is then applied.

    Academic text (1998)
  • After blanket polyimide deposition, vias are opened in the polyimide.

    Academic text (1998)
  • For all levels except the first, the starting surface was the planarized polyimide surface of the preceding level with flush, exposed vias.

    Academic text (1998)
  • The use of less-reactive polyimide dielectrics to make the cupping layer unnecessary is currently under development.

    Academic text (1998)
  • Nonplanar structures can create localized variations in polyimide thicknesses.

    Academic text (1998)
  • Polyimide is commonly used in electronics due to its high thermal stability and resistance to chemicals.

Surface Forms

polyimide singular
polyimides plural

Morphology

polyimide = imide (semi-transparent) = poly + imide

The word is transparently formed from the combining form poly- plus imide, but the specialized polymer meaning is unlikely to be fully recoverable for an average learner.

Etymology

Polyimide starts with poly- ('many') and ends with -imide (a chemical ending for a strong, heat-resistant part). So, polyimide is a material made of many repeating strong parts, which is why it is very heat resistant and used in electronics and industry.
