ActiveUS8945305B2Polycrystalline material growthSemiconductor/solid-state device manufacturingSemiconductor structureSelective deposition
Methods for depositing a material, such as a metal or a transition metal oxide, using an ALD (atomic layer deposition) process and resulting structures are disclosed. Such methods include treating a surface of a semiconductor structure periodically throughout the ALD process to regenerate a blocking material or to coat a blocking material that enables selective deposition of the material on a surface of a substrate. The surface treatment may reactivate a surface of the substrate toward the blocking material, may restore the blocking material after degradation occurs during the ALD process, and / or may coat the blocking material to prevent further degradation during the ALD process. For example, the surface treatment may be applied after performing one or more ALD cycles. Accordingly, the presently disclosed methods enable in situ restoration of blocking materials in ALD process that are generally incompatible with the blocking material and also enables selective deposition in recessed structures.

Method and apparatus for applying external coating to grid array packages for increased reliability and performance
InactiveUS20060278971A1Improve electrical performanceImprove reliabilitySemiconductor/solid-state device detailsPrinted circuit aspectsParylene coatingEngineering
A method and apparatus are disclosed for selective removal of a conformal coating from the solder balls of grid array packages such that the benefits of the coating are realized. An ancillary benefit of the invention is improved process-ability of the grid array package by improving the mechanical containment of the solder during the reflow process and improved electrical isolation between the individual solder attachment points. For example, a method for coating a ball grid array is provided, which includes coating the ball grid array with a thin layer of parylene. Next, the solder ball side of the part is butter smeared or squeegeed with a water soluble coating and assembled wet. A mask having holes in the same pattern as the balls in the grid, and a thickness that is about 80% of the height of the balls, is applied to the solder ball side of the part. This side of the part is then butter smeared again with the water soluble coating, and the entire assembly is allowed to dry. At this point, about 20% of each parylene-coated solder ball protrudes higher than the surface of the mask. The solder ball side of the part is then grit blasted with an abrasive material. The extent that the abrasive material removes the parylene coating from the solder balls is limited by the mask and the layer of water soluble coating. Therefore, the grit blasting removes the parylene coating from only the protruding areas (e.g., about top 20%) of the solder balls. Water is then used to remove the water soluble coating, and the parylene coated part is baked to remove moisture. Thus, a parylene coated ball grid array (or column grid array) is provided that is highly impervious to moisture, has a very high dielectric strength, and thereby improves the electrical performance and reliability of the surface mounted part.

ActiveCN107587119AHigh hardnessImprove insulation performanceChemical vapor deposition coatingPlasma technologyWear resistant
The invention provides a preparation method for a high-insulation hard nanometer protection coating of a composite structure, belonging to the field of plasma technology. According to the method, a reaction cavity is vacuumized and inert gas is introduced to allow a substrate to move, so organosilicon monomers with low dipole moment and high chemical inertia are screened out; the free volume and compactness of a coating are regulated and controlled through multifunctionality monomers, so the coating is allowed to have insulating properties and excellent protection performance and wear resistance at the same time; and an organosilicon coating is deposited on the coating with high insulating properties, and surface hard treatment is carried out so as to form a hard coating with a compact structure. The high-insulation hard nanometer protection coating provided by the invention has more excellent protection performance, insulating properties and wear resistance compared with conventionalcoatings such as parylene under the condition of same thickness. The preparation method provided by the invention overcomes the problems of poor wear resistance, too great thickness, low production efficiency and the like of conventional parylene coatings; and through hard treatment, a composite wear-resistant silica structure is increased in the coating, and the hardness and wear resistance of the coating are effectively improved.
