Slightly to a plastic like consistency. They are ready for use in the fabrication process. Once baked and when exposed to ultraviolet uv light the bonds that hold the.

Selectivity refers to the ability of an etchant to remove one material on the surface while leaving another intact. Used to evaluate the success or failure of the. Integrated circuits slideshare uses cookies to improve functionality and performance and to provide you with relevant advertising.

Extensive arrays of transistors resistors capacitors diodes strings of contacts and vias. Each square represents a completed integrated circuit. Etching selectivity and anisotropy.

It is a multiple step sequence of photo lithographic and chemical processing steps during which electronic circuits are gradually created on a wafer made of pure semiconducting material. Some of the locations in the array are occupied by process control structures and test dice. This process is repeated until 20 or more layers are developed over the surface of the wafer.
