A photomask is an opaque plate with transparent areas that allow light to shine through in a defined pattern. Photomasks are commonly used in photolithography for the production of integrated circuits (ICs or "chips") to produce a pattern on a thin wafer of material (usually silicon). Several masks are used in turn, … See more For IC production in the 1960s and early 1970s, an opaque rubylith film laminated onto a transparent mylar sheet was used. The design of one layer was cut into the rubylith, initially by hand on an illuminated drafting table (later … See more Leading-edge photomasks (pre-corrected) images of the final chip patterns are magnified by four times. This magnification factor has been a key benefit in reducing pattern sensitivity to imaging errors. However, as features continue to shrink, … See more The SPIE Annual Conference, Photomask Technology reports the SEMATECH Mask Industry Assessment which includes current industry analysis and the results of their annual photomask manufacturers survey.

WebA photomask is a fused silica (quartz) plate, typically 6 inches (~152mm) square, covered with a pattern of opaque, transparent, and phase-shifting areas that are projected onto wafers in the lithography process to define the layout of one layer of an integrated circuit. Numerous successive patterns guide deposition or removal of material from ... WebWhat is claimed is: 1. A multi-chip reticle, comprising: a transparent substrate having two or more separate chip images arranged in an array, each chip image of said two or more chip images having only one type of reticle image, wherein at least two of said two more chip images consist of different types of reticle images. life insurance medicaid spend down
