  • Patent number: 8088563
    Abstract: We have traced the detachment of photoresist during development of patterned features in the range of about 90 nm and smaller to a combination of the reduced “foot print” of the pattern on the underlying substrate and to the contact angle between the underlying substrate surface and the developing reagent. By maintaining a contact angle of about 30 degrees or greater, the detachment of the photoresist from the underlying substrate can be avoided for photoresists including feature sizes in the range of about 90 nm. We have achieved an increased contact angle between the DARC surface and a water-based CAR photoresist developer while simultaneously reducing CAR poisoning by treating the surface of the DARC after film formation.

  • Patent number: 7354733
    Abstract: We disclose methods of sorting or separating mixtures of living cells (e.g., eukaryotic, prokaryotic, mammalian, pathogenic, bacterial, viral, etc.). We perform our methods by activating cell-selective photophoric labels, which photosensitize and chemically reduce a photosensitive metal compound to form metal grains, particles or crystals. The metal adheres to the cells and forms the basis for sorting or separating different cell types. Photophoric labels may include chemiluminescent agents such as peroxidase enzymes activated with peroxidase substrates capable of luminescence. Photosensitive metal compounds may be present in a light-sensitive matrix or emulsion containing photosensitizable metal compounds, which form metal grains, particles or crystals upon exposure to a developer solution. Developer solutions are formulated to substantially allow living cells to remain viable after exposure to the developing solution.
