The most significant characteristic of these materials is their excellent superconducting properties and stability. With this foundation, the first step in fabricating quantum superconducting materials is to prepare the substrate.
Next, we will discuss the role of the substrate. The substrate is the basic structure used to support the superconducting material. Through experiments, single-crystal silicon or sapphire has been found to be the best substrate material.
When sapphire was mentioned, Xing Baohua immediately thought of a small county town in a neighboring city in central Shandong that was famous for its sapphire production. Well, at least a material supplier was found.
Continuing with the expert's concept, the substrate needs to undergo meticulous surface treatment and cleaning to ensure that the superconducting material can grow uniformly on it. Then, in a photolithography machine, a thin film of the superconducting material is grown on the substrate using techniques such as molecular beam epitaxy or chemical vapor deposition.
These technologies enable control over the growth rate and thickness of materials, as well as their crystal structure and orientation. During growth, strict control of temperature and atmosphere is required to ensure that the superconducting material grows in an optimal crystalline state.
The following section describes how to micro-process superconducting materials.
The focus is on explaining how photolithography is used to construct the desired circuit structure on superconducting materials. This includes explaining what photoresist and photoresist templates are used in photolithography, and how the circuit pattern is transferred onto the superconducting material through exposure and development processes.
Then, the superconducting material is etched using techniques such as ion beam etching or chemical etching to form the required circuit structure.
The remaining steps are the same as for semiconductor chips: testing and packaging the superconducting material. The description of the testing process includes measuring performance indicators such as the resistivity and superconducting transition temperature of the superconducting material.
After reading it, Xing Baohua unconsciously lit a cigarette. This wasn't just wild speculation; it was practically a manufacturing process.
Moreover, this expert has top-notch skills in chip manufacturing and photolithography; he wouldn't have written this without decades of immersion in the industry.
Xing Baohua searched for the author's name but only found two smaller letters: XY?
Another abbreviation! Xing Baohua really hates abbreviations these days.
This article is a treasure. Xing Baohua really wants to try it out, since he has plenty of lithography machines, whether for single-crystal silicon or sapphire!
The only thing missing is an architect.
We need to invite this expert, but well, that's just a thought; I doubt he'd come even if you beat him to death.
Then kill him.
This malicious thought lingered in Xing Baohua's mind, refusing to leave.
With this document, it was clear that Lewells hadn't fooled him; he had given him the results of various IBM experiments and data over the years.
Did they empty out all of IBM's research and development results?
So, what about the virus on the hard drive? Who downloaded it?
