Web25 jan. 2015 · Contact-free proximity lithography in contrast allows a convenient and economic large scale production capability with an almost unlimited mask life. However, the separation between mask and substrate implies that not the mask geometry itself but its defocused near field diffraction pattern is recorded ( Fig. 1 ). Webmanufacturing for years. Now a days X-ray lithography is used. X-ray whose wavelengths are 4 to 50 Ao are useful for X-ray lithography, by means of which all the above three disadvantages cab be overcome. 4 X-RAY LITHOGRAPHY When electron from the electron gun strikes the target, then there is ejection of electrons from the inner most shell of ...

WebDescription. Lithography is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone or a metal plate with a smooth surface. It was invented in 1796 by the German author and actor Alois Senefelder and was initially used mostly for musical scores and maps.
