Several days passed in the blink of an eye. During these few days, Richard hardly left the house and was busy in the Garden of Eden.
This made Wan An anxious.
In a two-story wooden building.
After hearing the latest report from his student Mas, the wizard Wan'an frowned deeply and asked with some annoyance: "So, in the past few days, except for one time when he went out to look for special gems, there has been no other movement. ?”
"Yes." Mas replied honestly.
"Damn it." Wan An cursed in a low voice and walked around the room. As he walked, he muttered to himself, "It shouldn't be. Why is it suddenly like this when things are going well? Could it be..."
Wan An thought of something, looked at Mas with wide eyes, and asked seriously: "By the way, is it possible that you were exposed and the other party noticed it?"
"This -" Mas hesitated, then shook his head vigorously, "No, teacher, I am very careful every time to ensure that I am not discovered by him."
"What's going on?" Wan An shouted, feeling very bad.
Mas huddled in the corner and didn't know how to answer. He touched his hungry belly, quietly took a piece of fish and stuffed it into his mouth, chewing hard and quietly. Seeing Wan An looking at him, he quickly stopped chewing and said, "Teacher, I really don't know."
Wan An glanced at Mas and ordered: "Okay, if you don't know, just go out and keep an eye on that kid. If anything happens, report to me immediately."
"Oh." Although Mas was reluctant, he still responded helplessly and walked out of the door.
…
A few days later, in the Garden of Eden, in the main laboratory.
A strange-looking instrument was erected. At a glance, it looked like a cracked copper bell.
After Richard adjusted the instrument, he took out the metal piece he made. He made a total of nine ten-centimetre-square metal sheets, and spliced them together horizontally and vertically to form a complete mask.
The assembled 30-centimeter-square mask was stuck in the middle of the instrument with a "snap" sound, about one meter above the ground. After locking it firmly, Richard took out another one-centimeter-square film - it was The mask area is 1/900th.
Putting this tiny piece of negative film coated with photoresist carefully at the bottom of the instrument, it stuck and locked with a "pop" sound. Richard began to adjust the lenses located in various parts of the instrument.
The function of the lens is to adjust the propagation of light to ensure that the light from the light source can illuminate the entire mask, shrink after passing through the mask, and then illuminate the tiny negative film according to a specific ratio to complete photolithography.
This was a delicate job. Richard kept adjusting and testing, and it took him a long time to complete it.
Afterwards, Richard took a deep breath, pressed his hands on both sides of the instrument, and closed it hard. There was just a "click" sound. The instrument originally looked like a copper bell that was split from the side, but now the bell is closed.
Richard pressed a button on the outside of the "Bronze Bell", and a "buzzing" sound sounded, and the air inside began to be sucked out to ensure that the inside of the instrument was in a vacuum state.
After completing this, Richard checked it again to make sure there was no problem. He reached out and pressed a button on the top of the instrument, which was the light source switch.
"Crack!"
The light source is turned on, and in this medieval wizarding world, the first chip lithography has officially begun!
Through the transparent panel in certain parts of the instrument, you can see that the inside seems to be a little brighter, but in fact there is no change, it is just an illusion.
Because the light source does not emit visible light.
Generally speaking, the wavelength of light that normal human eyes can perceive is between 400 and 760nm. A few more sensitive people can expand the range to between 380 and 780nm.
The current light source emits deep ultraviolet light with a wavelength of 200nm to 350nm, which is completely outside the visible range and cannot be seen by the naked eye.
This kind of deep ultraviolet light has a special energy response and is widely used on earth for air sterilization in water purification plants, hospitals, and dust-free workshops of factories. Now that the inside of the instrument is evacuated, the deep ultraviolet rays avoid reacting with air and can be used directly for photolithography.
In fact, if extreme ultraviolet light between 10nm and 14nm is used for lithography, the effect will be better. This is considered the technology of the fifth generation lithography machine on earth. However, considering the difficulty of implementation and the fact that it is only a practical attempt at present, Richard did not make it so complicated and planned to upgrade the technology bit by bit after achieving certain results.
As Richard watched, the photolithography machine was running steadily, and invisible light beams passed through the mask and lens, and concentrated on the one-centimeter-square negative.
There is no interlacing, no confusion, and the invisible light still strictly follows the physical theorem of straight-line propagation, projecting the pattern of the mask onto the film with incomparable accuracy and reacting with the photoresist applied on the surface.
At this moment, invisible light forms the most precise knife - the Carving Knife of Light.
Using nanometers or even smaller lengths as standard units, they slide back and forth silently in the photoresist, allowing the projected pattern to be fixed and formed bit by bit.
The whole process is without any sound, not even any movement, any light - neither visible nor audible. But the changes were indeed carried out, and finally, as expected, the negatives turned into qualified chips.
In the whole process, there was no prayer to the gods, no blessing from ancestors, no unknowable mysterious power coming, the only real thing was technology - the power of technology.
…
For a long time…
"Ding! Ding! Ding!"
A green indicator light on the lithography instrument flashed, indicating that the lithography was completed. Richard carefully opened the instrument, took out the chip, then placed it in another assembled instrument aside, and began to rinse with developer to allow the photoresist to coat. The pattern is fully revealed, and then a series of subsequent processes are performed.
In the end, Richard got a standard spell chip.
A thin spell chip the size of a fingernail was placed on Richard's fingertips and he observed it carefully. After a moment of thought, an extremely fine free energy element surged out from the source of the spell and was injected into the spell chip.
"Buzz!"
Richard clearly felt the obvious mana fluctuations and reverberations in the chip, which was obviously working. However, because too little free energy element was injected, the effect disappeared without a chance to show itself.
Richard's eyes brightened, and the reaction of the spell chip fully demonstrated that his previous plans, conjectures, and experiments were correct. The "World-Destroying Glove" could be produced with the help of chip technology on Earth.
Then the next step is... to continue making.
The magic patterns involved in this chip on the fingertip are only about one-tenth of the total number of magic patterns in the "World-Destroying Gloves". If the "World-Destroying Gloves" were really to be made, nine more would be needed.
nine!
