4958 results about "Electrostatic discharge" patented technology

Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown. A buildup of static electricity can be caused by tribocharging or by electrostatic induction. The ESD occurs when differently-charged objects are brought close together or when the dielectric between them breaks down, often creating a visible spark.

Reduced Susceptibility To Electrostatic Discharge During 3D Semiconductor Device Bonding and Assembly

A method to reduce electrostatic discharge susceptibility when assembling a stacked IC device. The method includes coupling a ground plane of a first semiconductor device and a ground plane of a second semiconductor device to substantially a same electrical potential. Active circuitry on the first semiconductor device and active circuitry on the second semiconductor device are electrically coupled after the ground planes are coupled. Electrically coupling the ground planes of the first and the second semiconductor device creates a preferred electrostatic discharge path to ground, thus minimizing potential damage to sensitive circuit elements.

Silicon-on-insulator and CMOS-on-SOI double film fabrication process with a coplanar silicon and isolation layer and adding a second silicon layer on one region

Silicon is formed at selected locations on a silicon-insulator (SOI) substrate during fabrication of selected electronic components, including resistors, capacitors, and diodes. The silicon location is defined using a patterned, removable mask, and the silicon may be applied by deposition or growth and may take the form of polysilicon or crystalline silicon. Electrostatic discharge (ESD) characteristics of the SOI device is significantly improved by having a thick double layer of silicon in selected regions.

Complementary zener triggered bipolar ESD protection

An electrostatic discharge (ESD) protection clamp (61) for I / O terminals (22, 23) of integrated circuits (ICs) (24) comprises an NPN bipolar transistor (25) coupled to an integrated Zener diode (30). Variations in the break-down current-voltage characteristics (311, 312, 313, 314) of multiple prior art ESD clamps (31) in different parts of the same IC chip is avoided by forming the anode (301) of the Zener (30) in the shape of a base-coupled P+ annular ring (75) surrounded by a spaced-apart N+ annular collector ring (70) for the cathode (302) of the Zener (30). Even though an angled implant (51, 86, 98) used to form the N+ annular collector ring (70) causes location dependent variations in the width (53) of the Zener space charge (ZSC) region (69), the improved annular shaped clamp (61) always has a portion that initiates break-down at the design voltage so that variations in the width (53) of the ZSC region (69) do not cause significant variations in the clamp's current-voltage characteristics (611, 612, 613, 614).
