Problems solved by technology

However, these cleaning solutions have their own insurmountable shortcomings: more chemicals are consumed and the cost is high; they are volatile and highly toxic, endangering the safety and health of operators and polluting the environment; they have certain corrosion and damage to devices.
However, the effect of removing dust and particles is relatively poor, especially the effect of removing metal particles is not ideal

Abstract

The invention relates to composition, a preparation method and application of a solid cleaning adhesive. The solid cleaning adhesive comprises a hard monomer, a soft monomer, an organic solvent, an initiator, other functional aids and the like, and is prepared through polymerization and a series of posttreatment. The prepared solid cleaning adhesive is a solid cleaning product with certain adhesion, remove solid microparticles, dust and metallic pollution on surfaces and in gaps of chips and devices through the adhesion and high deformability of the surface of the material, ensures no residue or secondary pollution, cannot scratch or damage the chips and the devices, is harmless to a human body, and can be widely applied to semiconductors, microelectronic devices, printed circuit boards, television picture tubes, precision instruments, liquid crystal displays, computer keyboards, equipment in automobiles, mobile phones, audio / video equipment and the like.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a solid cleaning glue and a preparation method thereof. Background technique [0002] With the development of microelectronics and semiconductor technology, the integration level of VLSI has increased rapidly, the feature size of devices has been continuously reduced, and the requirements for surface contamination of substrate chips have become more stringent. In the preparation process of VLSI, the surface state of the chip and the removal degree of pollutants are one of the most important factors affecting the yield of the wafer and the quality and reliability of the device. The chip manufacturing process has to go through oxidation, film formation, diffusion, photolithography, epitaxy and other processes, and some pollutants will inevitably be produced, such as particles (dust, human secretions, fibers, quartz powder, etc.), organic matter (photoresist , grease, wax, ...
