TOKYO – Renesas Electronics Corp., the world’s largest semiconductor manufacturer, has shut down three major factories in Japan after a major earthquake shook the country’s northeast, causing a tsunami, blackouts and severe transportation.
Renesas said the three plants, his Naka, Takasaki and Yonezawa plants, are close to the quake site, which was centered on the Pacific coast from the city of Sendai. A 7.4-magnitude quake shook cities as far away as Tokyo when it struck shortly after 11:30 p.m. March 16th.
Any long-term disruption to Renesas ’exit could expand the global automotive industry, which is already immersed in the shortage of semiconductors that has damaged production and sales. The three affected plants produce chips used in the automotive industry.
The quake struck nearly 11 years ago, on March 11, 2011, in the same area as the 9.0-magnitude earthquake and the epicenter of the devastating tsunami. for a month.
In the latest natural disaster, Renesas said on March 17 that it had recovered electricity from two power plants that had lost power overnight. The company is currently evaluating its impact on equipment and products, as well as the safety of facilities and the condition of clean rooms.
Renesas said he could not say when production would begin at the Naka and Takasaki plants. The company said it had partially resumed production of some test lines at the Yonezawa plant.
The Naka and Yonezawa plants make microcontrollers for automotive and industrial use. The Takasaki plant makes PMOS chips that are used to convert AC-DC power.
Power plants automatically shut down when power is cut off. Although there is no damage, it will take several days for the facility to be fully restarted, a Renesas spokesman said.
Only one worker was injured, with a minor injury.
Honda Motor Co. and Nissan Motor Co. said their plants were operating normally the morning after the quake. Toyota said it had suspended morning shifts at two assembly plants near the quake site to conduct security inspections and would later decide when to start again.
The quake killed at least three people and injured 170 others, according to the Japanese public broadcaster NHK. It caused a small tsunami and also diverted the famous Japanese bullet train. The blackouts cut off electricity to Tokyo, where buildings were shaken and trains stopped.
Will the chip shortage end?

This recovery may come gradually, however. Pat Gelsinger, CEO of Intel chipmaker, told reporters last week that “the cuts are expected to last through 2022 and 2023 with additional improvements this time around.” The increase in improvements means that car buyers do not expect prices to rise quickly.

How do Charges move in semiconductors?
When an electric field is applied to a metal, the negatively charged electrons accelerate and carry away the current that is generated. The charge in a semiconductor is not only carried by electrons. Positively charged holes also carry a charge.
How does current flow in semiconductors? The current flow in a semiconductor is generated by the motion of the charge carriers, both in the conductor and in the valence bands. As described in Chapter 4, the floating charges in the conductor band are electrons and the ones in the valence band are holes.
How do holes move in semiconductors?
Holes in a crystal or semiconductor crystal lattice can move through the lattice in the same way as electrons can, and they can act like positively charged particles. They play an important role in the operation of semiconductor devices such as transistors, diodes and integrated circuits.
How do positive holes move in semiconductors?
An electron within the valence band can fill a hole, leaving another hole in its place. This way it appears to be moving a hole. In front of an electric field the electrons move in one direction and the holes move in the opposite direction.
How do holes move in an intrinsic semiconductor?
When a pure silicon electron passes through a gap, it leaves an electron gap or “hole” in the ordinary silicon lattice. Due to an external voltage, both the electron and the hole can move through the material.
Do the holes actually move in semiconductor?
The holes do not move. It is an electron that takes a hole and leaves an empty hole behind it. So it seems that the electron moved towards the positive terminal and the hole towards the negative terminal.
Do the holes actually move in semiconductor?
The holes do not move. It is an electron that takes a hole and leaves an empty hole behind it. So it seems that the electron moved towards the positive terminal and the hole towards the negative terminal.
Do holes flow in a conductor?
There are no hole currents in the conductors because they overlap the valence and conduction bands. In conductors, electrons bind to the nucleus so that they can be easily released at room temperature.
Do holes actually move?
The holes are also movable. An electron within the valence band can fill a hole, leaving another hole in its place. This way it appears to be moving a hole. In front of an electric field the electrons move in one direction and the holes move in the opposite direction.
Do the holes actually move in Hall effect?
Yes, due to the external electric field, it is the electrons, rather than the holes, that move to generate current. Both generate an electric current in the same direction as the outside electric field.
What are the charges carries in semiconductors?
The majority and minority carriers are electrons in type N semiconductors, while in p-type semiconductors they are holes. Not so many cargo carriers are called minority carriers; In n-type semiconductors they are holes, while in p-type semiconductors they are electrons.
What are the charge carriers in semiconductors Class 12?
In the N-type semiconductor, the charge carriers are electrons (most carriers) and holes (minority carriers).
What are the charge carriers in semiconductors Mcq?
Solution: In conductors, electrons are charge carriers. But in semiconductors, both electrons and holes are charge carriers and will be involved in the conductor.
What are the two charge carriers in semiconductors?
In semiconductor devices such as diodes, two charge carriers — electrons and holes — combine to form a current.
