激光刻蚀和RIE是干法黑硅刻蚀，可精确控制微观形貌结构，在硅片表面形成

Laser etching and RIE are dry black silicon etching, which can precisely control the micro-topography and form a neat peak or parabolic pit structure on the surface of the silicon wafer. It has nothing to do with the crystal orientation, but the process cost is high and the conditions are harsh.

Can animals also think? Yes, they also use their brains. Here are a few examples:People put the chrysanthemum in one place, deliberately let a little orangutan see it, and then let out dozens of its companions. When they are with their companions, the little orangutan is very quiet. Three hours later, when all his companions were asleep, he stood up quietly and secretly found the grapes to eat.There was a crow. Once, his master gave it a piece of dry bread. The crow pecked it with his mouth and found that the noodles were hard. He picked up the bread and went away. It didn' t take long. Wu stopped for a while, put the dry bread in a box for chickens to drink water, and then came out again. The bread became soft after water, and the crow ate it bit by bit.The master changed the basin to a different place, and gave dried bread to Wu Chu people to see what to do with it. , una carrying dry bread also walked to the place where the basin was originally put, but there was nothing there. He walked several times without taking out the dry bread. Finally, he found that there was water in the bowl where the dog ate, so he put the bread in and ate it.In zoos, people sometimes see elephants sucking coins with their noses. Once, a man tried so hard that he threw a coin out of the railing and against the wall. The elephant couldn't reach it even though it had a long nose to suck. People thought it would just forget it, but the elephant stared at the coin and began to use his head. In a short time, the elephant had a way. It pushed its long nose out of the railing, sucked the tail gas, and forced it against the wall once. The tone was like the wind. When it met the wall, it came back and brought the coin. The elephant easily absorbed the hard coin, and the tourists clapped their hands happily.There is a monkey, which is usually tied to a tree with pure seeds. Some black monkeys don't pay attention to it, and they often fly down quickly, robbing the monkey of all its food, which makes the monkey often upset. One morning, the monkey seemed to have something wrong, and it looked very uncomfortable. It took a few steps slowly, and then fell to the ground. Those birds died for it, so they flew down together. Going to eat all the monkey's food, the monkey is really like a dead one. There is a Wuzhen that does not move. It barks and jumps to the monkey's side. Unexpectedly, the monkey suddenly jumped up, grabbed it and bit it to death. Since then, the black magpies have never dared to cover the monkey's food again.
