This TFG is going to deal with a current problem that is weighing down several industries
with millionaire losses and even temporary closure of factories due to lack of materials.
It is a crisis in the supply of semiconductors.
To put this in context, these semiconductors, or "chips", are in theory small flat parts,
composed mainly of silicon, and are the basis for the assembly of an electronic circuitry,
which is mainly composed of small transistors.
Two types of integrated circuits are conceived: logic chips and memory chips. The first
group includes processors (CPUs) in electronic devices or graphics processing units
(GPUs), while the second category refers to working memory (RAM) and flash (NAND).
On the other hand, the degree of sophistication of a chip is usually measured by the
space separating the teeth of the transistors: the less empty space there is, the faster
the information flows and the more components fit on the same board. Today, this space
is reduced to just two nanometres1 in the most advanced semiconductor devices. Since
their appearance in the mid-20th century, microchips have become smaller and smaller
and more efficient, extending their usefulness to increased objects. In fact, it is becoming
increasingly difficult to find an electrical device that does not contain some kind of chip.
From mobile phones to computers and tablets, from microwaves and ovens to
refrigerators, cars and vehicles of any kind, toys, video consoles, televisions, medical
and military equipment... Additionally, the growing use of the internet in recent decades
has required the installation of new and gigantic servers and data centres capable of
storing and processing so much information, for which state-of-the-art microchips are
required. (Almagro, 2021, Libremercado).
The manufacturing process of a microchip is as follows, silicon which is the basis of all
modern microchips, silicon has special properties because it is what we call a
semiconductor, that means that depending on how it has been treated silicon can
conduct or block electric current, it is this property that makes it perfect as a support for
the millions of tiny transistors needed to make a modern microprocessor. The problem
is that because these transistors are so small, the silicon base on which they rest has to
be absolutely perfect, so it took decades to perfect the process of producing silicon with
a perfect single-crystal structure. It starts with polycrystalline silicon or polysilicon, which
is heated to 1,420 degrees Celsius in a special sealed furnace. This furnace has been
purged with argon gas to remove air. The molten silicon lake we obtain is then spun in a crucible and a silicon crystal is introduced to act as a seed. This crystal has the
dimensions and shape of a pencil and rotates in the opposite direction as the molten
polycrystalline silicon cools down and the crystal, which acts as a seed, separates at a
rate of one and a half millimetres per minute.
The result is a single silicon crystal that weighs about 200 kilos and has a diameter of
about 200 millimetres. The crystal is so strong that it supports its entire weight with a
single 3 mm thick wire. Specifically in this research we will address the problem of this
crisis in the video game and electronics industries. These are especially important
industries in the world economy, on which many jobs depend, and which, if this crisis
continues, could seriously affect the economy of many countries and their infrastructures,
as these semiconductors are present in all electrical appliances. [-]
