Latest Patents

Cline's most recent inventions include:

1. **Ionization Test for Electrical Verification** - This patent describes a method and apparatus for conducting non-contact electrical tests to identify both opens and shorts in electronic substrates. The process involves exposing top surface electrical test features to an ionization source under ambient conditions while measuring subsequent charge buildup as a drain current through probes that contact corresponding bottom surface features. Opens are determined by an absence of a drain current, while shorts are revealed by turning off the ionization source and re-measuring the bottom surface probes with varying biases applied.

2. **Method and Structure for Top-to-Bottom I/O Nets Repair in a Thin Film Transfer and Join Process** - This patent outlines a method for repairing a defective I/O net in a thin film transfer process. It details the provision of locations and capture pads on a thin film substrate, preferably ceramic, with a strategy for severing the defective net and connecting a spare location and capture pad to establish a Z-repair line embedded within the wiring structure.
