Flip chip, also known as controlled collapse chip connection or its abbreviation, C4, [1] is a method for interconnecting dies such as semiconductor devices, IC chips, integrated passive devices and microelectromechanical systems (MEMS), to external circuitry with solder bumps that have been deposited onto the chip pads.
According to IPC's standard J-STD-012, Implementation of Flip Chip and Chip Scale Technology, in order to qualify as chip scale, the package must have an area no greater than 1.2 times that of the die and it must be a single-die, direct surface mountable package.
A Flip-Chip module is a component of digital logic systems made by the Digital Equipment Corporation (DEC) for its PDP-7, PDP-8, PDP-9, and PDP-10 computers, and related peripherals, beginning on August 24, 1964.
A thermal copper pillar bump, also known as a "thermal bump", is a thermoelectric device made from thin-film thermoelectric material embedded in flip chip interconnects (in particular copper pillar solder bumps) for use in electronics and optoelectronic packaging, including: flip chip packaging of CPU and GPU integrated circuits (chips), laser diodes, and semiconductor optical amplifiers (SOA).
3D packaging refers to 3D integration schemes that rely on traditional interconnection methods such as wire bonding and flip chip to achieve vertical stacking. 3D packaging can be divided into 3D system in package (3D SiP) and 3D wafer level package (3D WLP). 3D SiPs that have been in mainstream manufacturing for some time and have a well ...
Integrated circuit packaging is the final stage of semiconductor device fabrication, in which the die is encapsulated in a supporting case that prevents physical damage and corrosion. The case, known as a " package ", supports the electrical contacts which connect the device to a circuit board.
For example, the "micro-FCBGA" (flip chip ball grid array) is Intel's current [when?] BGA mounting method for mobile processors that use a flip chip binding technology. It was introduced with the Coppermine Mobile Celeron. [citation needed] Micro-FCBGA has 479 balls that are 0.78 mm in diameter. The processor is affixed to the motherboard by ...
In October 2001, ASE began volume production of wafer-level chip-scale packages. [13] Flip chip is a method of flipping the chip to connect with either substrate or leadframe. [14] According to the research firm Yole Développement, the flip chip technology market value is expected to reach $25 billion in 2020.
