Integration density

The integration density (formerly also packing density ) describes the number of transistors per unit area on integrated circuits .

Due to the constant scaling of the semiconductor components (primarily transistors) in microelectronic circuits, the term is usually only mentioned in connection with the currently most highly integrated processors . However, less specific figures are given than general trends. For example, it follows from Moore's Law that the integration density of CPUs doubles every 12 months (from 1975 every 24 months).

With the same chip area, circuits with a higher integration density enable a higher degree of integration (complexity of an electrical circuit). Since the chip areas from technology node to technology node for comparable products generally remain similar, the terms are often used synonymously in the literature.

Following the ICs, the concept of integration density is also the integration of components on printed circuit boards transmitted
