    Abstract: A new class of 3,4-dihydrocoumarin derivatives which are useful as photoactive compounds in a wide variety of applications including photoresists and other opto-electronic applications are disclosed and claimed. Preferred embodiments include ether, ester, carbonate, and sulfonate derivatives of 5-hydroxy, 6-hydroxy, and 7-hydroxy-3-diazo-4-oxo-3,4-dihydrocoumarins. These compounds exhibit very high photosensitivity in the deep ultraviolet (DUV) region (ca. 250 nm), and therefore, are useful as photoactive compounds in DUV photoresist formulations.

    Abstract: Methods for seeding and growing diamond films on planar and non-planar surfaced substrates and also for patterning the diamond films include mixing submicron diameter diamond particles and binder particles in carriers such as photoresist or water, and applying the mixture to a substrate surface. Treatment of the substrate by chemical vapor deposition then removes the carrier and grows the dispersed diamond particles into a diamond film. Notably, diamond particles having an average size of 25 nanometers form a particularly desirable mixture since the particles do not tend to settle out of the mixture, and also since these particles result in smooth diamond films. The mixtures can be applied onto non-planar surfaces by spraying, dipping, or dispensing and jet writing, and can be applied to planar and non-planar surfaces as a complete coating, as a line, or as a pattern. Patterning of the mixture, either when applying the mixture to a substrate or after applying the mixture, allows the formation of novel structures.
