This application discloses a wafer-level pattern modification method and an ion beam etching apparatus, applicable to the semiconductor manufacturing field. In this method, a target ion beam voltage is first determined based on the hardness grade of the material to be etched on the wafer surface. An initial pattern is formed on the wafer surface by the material to be etched. Then, based on a first ion beam incident angle and the target ion beam voltage, the initial pattern is modified on one side in a first direction using the ion beam to obtain a first modified pattern. Therefore, only one photolithography step is needed before ion beam etching to form the initial pattern, avoiding low product yield caused by overlay errors. Through ion beam etching, the initial pattern formed by the material to be etched on the wafer surface can be modified on one side in a highly controllable manner in a first direction parallel to the wafer surface, reducing the distance between adjacent patterns and improving the success rate of forming the first modified pattern, thus increasing the yield of products requiring small CD patterns.

This invention discloses a method for preparing Iota carrageenan. Using *Euphorbia tirucalli* as raw material, the raw material is washed to remove salt and sand, then alkali-modified in a potassium hydroxide solution. After acid neutralization, the raw material is directly soaked, ground, and ultrasonically extracted. The extract is then homogenized and finely filtered. A calcium chloride coagulant solution is added, and after mixing, only ethanol is added for dehydration. The precipitate is granulated, dried at low temperature, and pulverized to obtain high-yield, high-viscosity pure Iota carrageenan. This invention employs ultrasonic extraction technology, significantly improving the extraction rate of Iota carrageenan. The potassium salt formed during neutralization saves process water and provides a coagulant for the subsequent coagulation process. Furthermore, the addition of a low concentration of calcium chloride for coagulation greatly reduces the amount of ethanol used in traditional dehydration processes. This invention represents a novel, low-energy-consumption, high-yield, green extraction process for Iota carrageenan with broad application prospects.
