With a total of 2 patents, his work focuses on methodologies that enhance the reliability of electronic devices against ESD events.

Latest Patents

One of Tze Wee Chen's latest patents is a "Methodology for preventing functional failure caused by CDM ESD." This design methodology aims to prevent functional failures caused by CDM ESD events. It utilizes a transistor model to analyze the final states of cells, employing a simulator to identify invulnerable cells. Cells identified as potential failure sites are replaced with invulnerable cells that perform identical logic functions. If no identical function cell is available, an invulnerable buffer cell can be inserted to protect the potential victim transistor. This innovative approach ensures that the resulting design is guaranteed to be CDM ESD tolerant.

Another significant patent is the "Electrostatic discharge protection circuit employing a micro electro-mechanical systems (MEMS) structure." This ESD protection circuit safeguards a host circuit connected to a signal pad from ESD events. It features at least one MEMS switch that connects to the signal pad and a voltage supply source. During an ESD event, the MEMS switch shunts the ESD current from the signal pad to the voltage supply source. The design includes a passivation layer to reduce contact adhesion between the switch's contact structures, enhancing its effectiveness.
