摘要:
Method for selectively depositing metal onto ceramic and glass substrates by selectively melting a surface layer and thereafter contacting the melted surface with a seeding medium to deposit seed onto the melted surface. The seeded areas of the surface preferably are thereafter selectively plated with metal by contacting the surface with a suitable electroless plating solution.
摘要:
A curable composition containing an epoxide component that includes an epoxy polymer and hardening component, and zinc oxide, where the relative amount of said zinc oxide to said epoxide component is about 1:4 to about 2:1 and use thereof.
摘要:
By hydrolyzing an organoalkoysilane monomer at high concentration in solution to form a silanol, allowing the silanol to age to produce a low molecular weight oligomer, spin-applying the oligomer onto a substrate to form a discrete film of highly associated cyclic oligomer thereon, heat treating the oligomer film to form a modified ladder-type silsesquioxane condensation polymer, and then oxidizing the silsesquioxane in an 0₂ RIE, an organoglass is formed which presents novel etch properties. The organoglass can be used as an etch-stop layer in a passivation process.
摘要:
Contaminant is removed from holes by etching in a gaseous plasma by first removing contaminant from the vicinity of the edges of the hole. Next, a mask is provided in the vicinity of the edges to prevent etching by contacting with a gaseous plasma which is different from the gaseous plasma employed in the first etching step. The holes are then etched in a gaseous plasma to remove contaminant from the interior of the holes in the vicinity of the center of the holes, whereby the mask protects the edges from being etched.
