Drawing of a tape-automated bonding carrier and definitions of various parts of the TAB assembly. Tape-automated bonding (TAB) is a process that places bare semiconductor chips (dies) like integrated circuits onto a flexible circuit board (FPC) by attaching them to fine conductors in a polyamide or polyimide (like trade names Kapton or UPILEX) film carrier.

Color chips or color samples from a plastic pellet manufacturer that enables customers to evaluate the color range as molded objects to see final effects. A color chart or color reference card is a flat, physical object that has many different color samples present. They can be available as a single-page chart, or in the form of swatchbooks or ...
Surface activated bonding (SAB) is a non-high-temperature wafer bonding technology with atomically clean and activated surfaces. Surface activation prior to bonding by using fast atom bombardment is typically employed to clean the surfaces.
Compared to Al or Cu, it does not form an oxide. This allows to skip a surface cleaning procedure before bonding. [1] Copper has the disadvantage that the damascene process is very extensive. [5] It also immediately forms a surface oxide which can, however, be removed by formic acid vapor cleaning. Oxide removal doubles as surface passivation.
Interactive Forms is a mechanism to add forms to the PDF file format. PDF currently supports two different methods for integrating data and PDF forms. Both formats today coexist in the PDF specification: [37] [52] [53] [54] AcroForms (also known as Acrobat forms), introduced in the PDF 1.2 format specification and included in all later PDF ...
In printing, registration black is a black color that includes 100% of each of the process colors used. Typically these are cyan, magenta, yellow and black , [4] but if different colors are used, registration black marks are made with all of the colorants (inks). [4] Registration black is used for printing crop marks and registration marks ...
The decrease of temperature is based on the increase of bonding strength using plasma activation on clean wafer surfaces. Further, the increase is caused by elevation in amount of Si-OH groups, removal of contaminants on the wafer surface, the enhancement of viscous flow of the surface layer and the enhanced diffusivity of water and gas trapped at the interface.
