What is die substrate?

What is Embedded Die Substrate? Conventionally, active semiconductor chips (or dies) are mounted on top of a substrate for structural support and electrical interconnect.

What is a substrate in VLSI?

In electronics, a wafer (also called a slice or substrate) is a thin slice of semiconductor, such as a crystalline silicon (c-Si), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells. The wafer serves as the substrate for microelectronic devices built in and upon the wafer.

What is the difference between a die and wafer?

A die, in the context of integrated circuits, is a small block of semiconducting material on which a given functional circuit is fabricated. The wafer is cut (diced) into many pieces, each containing one copy of the circuit.

What is die in silicon wafer?

A die is the formal term for the square of silicon containing an integrated circuit that has been cut out of the wafer. Die is singular, and dice is plural.

What is die bond process?

Die bonding is a manufacturing process used in the packaging of semiconductors. It is the act of attaching a die (or chip) to a substrate or package by epoxy or solder, also known as die placement or die attach. The die is placed into a previously dispensed epoxy or placed into solder (eutectic).

What is the purpose of die attach?

Die attach is the process of making the electrical connection between the semiconductor device die and its package. Because it is the first packaging layer in contact with the die, its thermal characteristics are critical.

What is substrate in IC?

IC substrate (also known as IC package substrate) is a key special basic material used in advanced packaging, which is used to package bare IC (integrated circuit) chips. IC substrate acts as the connection between IC chip and PCB through a conductive network of wires and holes.

What is substrate in semiconductor?

The supporting material upon which or within which the elements of a semiconductor device are fabricated or attached. (2) (of a film integrated circuit): A piece of material forming a supporting base for film circuit elements and possibly additional components.

What is die processing?

Die preparation is a step of semiconductor device fabrication during which a wafer is prepared for IC packaging and IC testing. The process of die preparation typically consists of two steps: wafer mounting and wafer dicing.

What is eutectic die bonding?

Eutectic bonding is a die bonding technique, used primarily to produce hermetically sealed packages that are sensitive to outgassing of standard die attach materials. In optoelectronics applications for example, this often means two gold-plated surfaces being joined by lead-tin, gold-tin or gold-germanium solder.
