ABSTRACT:
In fabrication of articles, such as semiconductor devices, the articles are adhered to the surface of a magnetized carrier having grooves with a suitable adhesive. Preferably, the grooves are parallel and in sets which intersect each other. The articles are made susceptible to the attraction of a magnetic field. The adhesive is removed by the flow of solvent vapor and liquid through the grooves while the articles are retained in their original position by magnetic forces.
In an alternate method, the articles may be adhered initially to a nonmagnetic substrate, made susceptible to the attraction of magnetic field and transferred to a grooved, magnetized carrier. Any adhesive which clings to the articles is removed by solvent vapor and liquid as before.
