Latest Patents
One of his latest patents is a method of fabricating a segmented emitter low noise transistor. This invention implements a novel emitter scheme that maximizes the emitter perimeter to emitter area ratio of an integrated circuit transistor. By achieving improved low noise characteristics over the prior art, this innovation enhances the overall performance of the transistor. The emitter regions are disposed in discrete 'dotted' segments, which can be realized by etching into emitter regions defined by an appropriately formed photoresistive overlay. This method allows for modifications without changes to the fabrication process, effectively reducing the total emitter area by half while maintaining the total emitter perimeter unchanged. As a result, the noise-capacitance product of the transistor is reduced, leading to improved performance.
