US6040226 - Method for fabricating a thin film inductor -  03/21/2000 
A method is provided for the manufacture of precision electronic components such as resistors, inductors, and capacitors on a polymer or ceramic surface. The electronic components can be deposited and trimmed to precise or matched values without having precise depositions of all of the pre-patterned materials. Thin film electronic components are deposited on a surface, parameter values are measured or estimated, a correction offset file is generated, and the components are trimmed using adaptive lithography to a very close tolerance. A computer program can be used to enable the adjustment of electronic components by techniques such as changing the physical length of an inductor coil or resistor lead, or by changing a capacitor plate area.
US5872040 - Method for fabricating a thin film capacitor -  02/16/1999 
A method is provided for the manufacture of precision electronic components such as resistors, inductors, and capacitors on a polymer or ceramic surface. The electronic components can be deposited and trimmed to precise or matched values without having precise depositions of all of the pre-patterned materials. Thin film electronic components are deposited on a surface, parameter values are measured or estimated, a correction offset file is generated, and the components are trimmed using adaptive lithography to a very close tolerance. A computer program can be used to enable the adjustment of electronic components by techniques such as changing the physical length of an inductor coil or resistor lead, or by changing a capacitor plate area.
US5849623 - Method of forming thin film resistors on organic surfaces -  12/15/1998 
A method for fabricating a thin film resistor comprises applying a tantalum nitride layer over a dielectric layer, applying a metallization layer over the tantalum nitride layer, and patterning the metallization layer with a first portion of the metallization layer situated apart from a second portion of the metallization layer and both the first and second portions being at least partially situated on the tantalum nitride layer. In one embodiment, after patterning the metallization layer, the resistance value between the first and second portions of the metallization layer is determined and compared to a predetermined resistance value, and at least one of the first and second portions is trimmed to obtain a modified resistance value between the first and second portions that is closer to the predetermined resistance value than the determined resistance value.
