Latest Patents

Chung Lung Chang's latest innovations include two pivotal patents that focus on self-inspection mechanisms within semiconductor test systems. The first patent describes a semiconductor test system equipped with a self-inspection of the electrical channel. This system comprises a tester head, multiple parameter detection units, and a self-inspection controller. The various pin electronics cards within the tester head implement power, I/O, and drive channels. The self-inspection controller generates inspection signals for each channel, allowing for detection of response signals that enable the system to ascertain whether each electrical channel is functioning normally or if there are conditions such as open circuits, short circuits, or leaks.

His second patent expands on this technology specifically for Pogo towers. This system innovatively utilizes a short board and closed loops formed through various contacts to connect with Pogo pins on a load board. Similar to the first invention, the self-inspection controller tests each power channel, I/O channel, and drive channel to ensure they operate correctly before inspecting any wafers, identifying any abnormalities in the channels or Pogo pins.
