Wafer backgrinding is a semiconductor device fabrication step during which wafer thickness is reduced to allow stacking and high-density packaging of integrated circuits (IC). ICs are produced on semiconductor wafers that undergo a multitude of processing steps.
Wafer fabrication is a procedure composed of many repeated sequential processes to produce complete electrical or photonic circuits on semiconductor wafers in a semiconductor device fabrication process. Examples include production of radio frequency amplifiers, LEDs, optical computer components, and microprocessors for computers. Wafer ...
A wafer-level package attached to a printed-circuit board. Wafer-level packaging (WLP) is a process in integrated circuit manufacturing where packaging components are attached to an integrated circuit (IC) before the wafer – on which the IC is fabricated – is diced. In WLP, the top and bottom layers of the packaging and the solder bumps are ...
Wafer carriers or cassettes, which can hold several wafers at once, were developed to carry several wafers between process steps, but wafers had to be individually removed from the carrier, processed and returned to the carrier, so acid-resistant carriers were developed to eliminate this time consuming process, so the entire cassette with ...
The bonded wafers are characterized in order to evaluate a technology's yield, bonding strength and level of hermeticity either for fabricated devices or for the purpose of process development. Therefore, several different approaches for the bond characterization have emerged. On the one hand non-destructive optical methods to find cracks or ...
Wafering is the process by which a silicon crystal is made into wafers. This process is usually carried out by a multi-wire saw which cuts multiple wafers from the same crystal at the same time. These wafers are then polished to the desired degree of flatness and thickness.
Cream cheese frosting is simply a variation of buttercream frosting. Buttercream frosting is typically made with powdered sugar, butter and vanilla extract or another flavoring. Sometimes salt and ...
Wafer mounting is a step that is performed during the die preparation of a wafer as part of the process of semiconductor fabrication. During this step, the wafer is mounted on a plastic tape that is attached to a ring. Wafer mounting is performed right before the wafer is cut into separate dies. The adhesive film upon which the wafer is mounted ...
