    摘要: A photosensitive resin composition comprising a pre-imidized aromatic polyimide, which when coated on a silicon wafer, has a light transmittance at a wavelength of 365 nm of at least 1% and imparts low residual stress after cure. The composition can be patterned through I-line exposure followed by development with organic or alkaline solutions, and can be cured at relatively mild temperature to yield low-stress polyimide patterns. Electronic components having the polyimide patterns have high reliability.

    摘要: Water absorption resistant polyimide pastes (or solutions), are particularly useful to make electronic screen printable pastes and the electronic components made from these pastes. A group of soluble polyimides and their solvents were discovered to be particularly resistant to moisture absorption. These polyimide solutions optionally contain polyimides also containing cross-linkable monomers and/or thermal cross-linking agents. In addition, these polyimide pastes may optionally contain adhesion promoting agents, blocked isocyanates, metals, metal oxides, and other inorganic fillers. The polyimide pastes (or solutions) of the present invention have a polyimide with a glass transition temperature greater than 250° C., have a water absorption factor of less than 2%, and a have a positive solubility measurement.
