Thermocompression bonding Wikipedia

Thermocompression bonding describes a wafer bonding technique and is also referred to as diffusion bonding, pressure joining, thermocompression welding or solid-state welding.Two metals, e.g. gold (Au)-gold (Au), are brought into atomic contact applying force and heat simultaneously. The diffusion requires atomic contact between the surfaces due to the atomic motion.

Gold and Silver Wire Bonding Application Considerations

Nov 18, 2014· There are many types of plating finishes that are popular for use in wire bonding applications. High purity gold plating such as Type III to ASTM B488 of Mil-G-45204 is a tried and true staple for wire bonding finishes. It offers long term reliability in most applications including telecommunications and automotive markets and is typically the preferred option in high reliability

Thermocompression Bonding an overview ScienceDirect Topics

Gold has the benefit not to oxidize and to remain soft, while copper is prone to oxidization and work hardening [19]. Especially Cu-Cu bonding is a very attractive option for the vertical integration of the active parts or 3D stacking of ICs as the process provides both the electrical connections and the bonding medium in one step.

Wedgebonding problems with nickel gold plating

Jun 28, 2010· For some bonding devices a possibility is that the nailhead then goes up again; this causes the now loose gold thread to expose itself partly hanging in the air under the capillary hole of the nailhead and so a relatively long length of gold thread is now staying outside this nailhead.

Ribbon Wedge Bonding Semiconductor Digest

Wire bonding falls into two main classifications: ball and wedge bonding. Ball bonding is an omni-directional process. (i.e., the second bond can be at any 360° position from the ball), while ball bonding is used almost exclusively with gold wire and accounts for ~ 98 percent of all wire bonding done today.

Ball bonding Wikipedia

Ball bonding is a type of wire bonding, and is the most common way to make the electrical interconnections between a chip and the outside world as part of semiconductor device fabrication.. Gold or copper wire can be used, though gold is more common because its oxide is not as problematic in making a weld. If copper wire is used, nitrogen must be used as a cover gas to prevent the copper
