A solid state detection system includes a degenerate photo-parametric amplifier, wherein the PPA comprises a photo diode, and a periodically pulsed light source, wherein the photo-parametric, amplifier is synchronized to the pulsed light source with a phase locked loop that generates a pump waveform for the PPA at twice the frequency of the excitation pulse rate. Using the methods and apparatus herein, users can use a list of dynamic content from a variety of sources, determined at runtime and based on criteria that can change dynamically at runtime, in their process design. The metal contact structure is formed without a void or a key hole.
