Patent number: 6586791Abstract: An insulating layer in a field effect transistor is formed of superfine ceramic particles dispersed in a polymeric matrix. The characteristics of the insulating layer can be changed by varying the mix of ceramic particles and matrix components. Appropriate selection of components can provide a high dielectric constant material which is not subject to pinholes, has a high voltage breakdown and is chemically resistant. The material can be applied at relatively low processing temperatures, using a wide range of coating techniques, and is highly suited for use with polymeric substrates.Type: GrantFiled: July 19, 2000Date of Patent: July 1, 2003Assignee: 3M Innovative Properties CompanyInventors: Tzu-Chen Lee, Nelson B.

Patent number: 4430426Abstract: Silver halide emulsions lack stability in that their properties vary over a period of time. Various stabilizers have been used to reduce the rate and degree of variation. The combination of uracils and nitroso-substituted phenols has been found to provide a synergistic stabilization of speed in silver halide emulsions. Other stabilizers may be combined with those two classes to further improve the stability of the emulsion.Type: GrantFiled: June 4, 1982Date of Patent: February 7, 1984Assignee: Minnesota Mining and Manufacturing CompanyInventors: George W.
