What is the reason for making smaller and smaller chips? And why not focus on the development of advanced processes
On the development prospects of the script killing industry, market analysis here is not too much discussion, macro make people right, micro make money, here I just want to combine their own can do things as a small entrance, throwing a few script killing and their own U disk industry immature small ideas
What is the limit of silicon wafers to be engraved, but a layer of glue, after which this graphic layer of photoresist has to be used as a template to engrave the various structures on the chip, what is the means of using chemistry or physics after this photolithography?
chip factories need so much water for what? Part of it, cooling down, part of it, configuring solvents, and more of it is used to bathe the chips.
he origin of photolithography for chip manufacturing is with the United States, but why does the United States no longer produce photolithography now? How did the U.S. lithography machine, which once dominated the global market and held a technological advantage, fail in just ten years?
are the origins of photolithography and where is the future heading? What kind of evolution has lithography gone through…
What are the steps involved in taking apart a photolithography machine?
To make a chip, first of all, there must be light, how humans use the ethereal and invisible light to carve out a chip of the utmost delicacy, why photolithography is the basis of all processes in chip manufacturing
Chip as the most sophisticated industrial products of human civilization at present, its production process is extremely sensitive to impurity pollution…
In the last issue, we talked about how to take out silicon ingots and monocrystalline silicon rods from a pile of silica silicon sand, and will soon start cutting them into wafers; at the same time, it was also mentioned that from this step onwards, the road to domestic production of chips will enter the first link to be necked. This point, many students will certainly have doubts, because go online to search for monocrystalline silicon production capacity,..
