In the electronics hierarchy, integrated circuits (IC) can either be considered as the base or the apex and both of
these positions are conceivably correct. Being the initial point, primary
building block and foundation for majority of modern electronic systems, the IC
also stands for the crest in terms of electronic device (i.e. transistor)
density. As such, integrated circuits are not radical or monolithic electronic
form. According to fulfill the different packaging needs and requirements,
there are diverse types of ICs such as: digital, analog, sensor, RF, etc. In
this article, we will try to give you a concept about technologies associated
to IC packaging, pursuing, the components and methods used to generate these
absolutely necessary structures.
Although physical formations, applications and
input-output calculations of ICs can be different vastly, the roles and
operations of IC packages are lesser in number and more unchanging in purpose.
While the IC package has two basic and elementary functions, it has few other
roles to play as “keeper of the chip.” The main two functions are: 1) the IC
package safeguards the inner die & chip’s circuitry from tangible
impairment and from any kind of defilement like moisture and dust and 2) the IC
package also helps with redistributing the Input & output of the chips
circuitry to a user-friendly component size for use by its end user. Other than
these two major roles, a number of potential secondary roles, such as allowing
a structure more appropriate for standardization, allowing a fervent heat
course away from the chip, providing protection from the probability of errors
because of alpha particles and other various radiations, and providing a
structure that more handily allows electrical experiment and burn-in by the
chip's maker.
The IC package may also be effective to connect
more than one IC both directly to one another utilizing standard
interconnection technologies like wire bonding, and indirectly utilizing
interconnection pathways available on the package such as those used in hybrid
IC packages and multi-chip modules (MCMs) and currently in system-in-package
(SiP) and other methods covered under the broader concept of volumetric system
miniaturization and interconnection (VSMI). The packages also make it simpler
to install the ICs in different types of equipment, as every package comprises
leads which may be either plugged into corresponding sockets or plugged into
mounting frames. Various types of materials are used to manufacture IC
packages.
With the escalated interest and expansion of
micro-electromechanical systems (MEMS) devices and lab-on-chip devices, the
package provides more capacity, such as localized access to the environment, a
necessity for pressure variation, or as needed for chemical or atmospheric
condition resolution. There is also increasing interest and activity in the
advancement of optoelectronic packages to address the requirements of this
growingly significant area of activity. There has been a notable ground shift
in modern times related to the significance and spreading role of IC packaging,
to the point that the IC package has gained a measure of balance in terms of
importance with the IC itself. Because the performance of the IC is gated by
the IC package in many cases.
