When we talk about recording in a dead container we must carefully separate the two conditions. On the other hand, we have technology and equipment that can record the wafer to specific nanometers using waves.
On the other hand, we have mask manufacturers (photomasks), in charge of allowing accurate recording of the optical illumination of each machine. It is a subconscious way of being apart from one another, so the industry is at odds between and at the same time in oils of large size, small grain, pure and dense.
Silicon triangles and nanometers are very sensitive to change and everything is usually very slow, because very high accuracy must be guaranteed to give the smallest amount of so-called «whites
The business of empty masks and their importance
To make the chips as perfect as possible, you need an important component that has been adapted to the new EUV technology: a blank mask. This type of mask is specifically designed to work as a background for the graphics tab, because without it you can't achieve chip recordings.
In order to create an EUV photomask, an empty EUV mask is required in advance, which would not be a problem if it were not for the fact that only two manufacturers in the world could make it because of their high difficulty: AGC and Hoya.
This type of mask determines the use and quality of the image mask. The process is simple: the best quality blank mask is produced (the highest price $ 100,000 currently with a mask) so that when completed, it is sent to the mask artist and can list your design in the clip below.
Thousands of image masks, but very few blank mask elements
What distinguishes an image mask from an empty mask is that the first one corresponds to the IC design of each constructor, that is, if NVIDIA requires 10 different Ampere GPUs, the manufacturer of 10 different image mask designs for each specific IC.
Instead, a blank mask type will be used to place each drawing of Huang's chest material. Therefore, i photos they are great templates for each chip design.
When each photomask is already printed and has a blank scanner underneath it and just above the passage, they are both placed in a lithography scanner where the light is transmitted and the images are finally copied into the transistors and their design.
Therefore, having an empty mask with high purity and stainlessness is more important than having a very efficient Photomask or a very pure dead one, since the failure in this case translates into an unambiguous text on each frame.
For this reason, the amount of CPU or GPU chip that is running and running will vary between one, mainly due to this condition in the use of an empty mask in combination with the wafer quality.
