Humble sand.
2
This is what the building blocks of the future are made of.
3
But making them is a long process compromising a great many steps.
4
First, the silicon dioxide in the sand has to be converted into pure silicon.
5
After that, it is cut into wafer -thin disks.
6
In Dresden, these raw wafers are 300 millimeters in diameter and less than a millimeter thick.
7
In our clean room, up to 35 ,000 chips are then made from each of these disks.
8
In numerous process stages, the wafers are given their characteristic surface structure.
9
After coating with a photoresist layer, the wafer surface is exposed, developed, and etched.
10
This results in the desired conductor structure.
11
Such structures are hundreds of times finer than a human hair.
12
Dopants are then implanted in the material to increase the electrical connectivity of parts of the semiconductor. In subsequent phases,
13
this and other process steps are repeated until the entire layout of the chip has been deposited on the wafer.
14
This involves heating the wafer to more than 1 ,100 degrees Celsius, in some cases up to 27 times.
15
Up to 200 measurements are done, and up to 26 exposures.
16
All in all, this can mean as many as 700 processing steps and 14 weeks processing time.
17
Once this is completed, the microchip is assembled from as many as 30 such layers, like a mini skyscraper.
18
Each layer has its own function.
19
Interconnecting them makes the microchip highly complex.
20
Semiconductor chips, the building blocks of our future.

Sobre esta lección

¿Qué es la Técnica de Shadowing?

Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
