(sc) a thin film of an optical-grade polymer that is stretched on a frame and secured to a mask or reticle. This solves the problem of airborne contamination forming on the mask. The pellicle keeps the dirt out of the focal plane.
IS A FILM ON THE TOP OF THE BEER AND SIGN OF AN INFECTION
found in Euglenophyta; a series of strip-like plates underneath the cell membrane arranged in a spiral, pellicle may be rigid or plates may be able to slide as the cell expands and contracts during movement.
thin protective membrane in some protozoa
a thin membrane or plate that is suspended above the pattern by a metal frame
a transparent thin-film dust-proof cover to prevent foreign matter from contaminating the photomask and so affecting the transfer pattern
The first step in plaque formation, the pellicle is a clear, thin covering containing proteins and lipids (fats) found in saliva. Pellicle is formed within seconds after a tooth surface is cleaned.
a thin transparent layer stretched over a frame above the surface of a mask or reticle. Pellicles are used to block particles from reaching the mask or reticle surface where the particle would be in the focal plane. Any particles on the pellicle surface are out of the focal plane and should not form and image on the wafer being exposed.
A thin nonbacterial film from saliva that covers the teeth
Another term for the thin skin that forms on drying paints such as oils.
Thin film used in one-shot color cameras as a semi-reflecting surface.
The pellicle is a thin layer supporting the cell membrane in various protozoa, protecting them and allowing them to retain their shape. They vary from flexible and elastic to rigid. In ciliates and Apicomplexa, it is formed from closely packed vesicles called alveoli.
