Problems solved by technology

But at the same time, Invar alloys are all obtained by smelting, which requires high energy consumption and high technical requirements, so the price is quite high, and the price of a single piece is as high as 1,000 yuan or more.

Abstract

The invention discloses a metal mask plate for vapor deposition produced from a nickel-iron alloy. The metal mask plate is produced by using an electroforming process, and from a nickel-iron alloy material; and the nickel alloy material comprises two elements of nickel and iron, wherein the iron content is 40% to 55% and the nickel content is 45% to 60%. The metal mask plate for vapor deposition of the invention has physical properties similar to an Invar alloy plate, high plate surface brightness, high uniformity, good plate surface quality, and a lower cost compared with a mask plate produced from an invar alloy, thus saving the cost. At the same time, the linear thermal expansion coefficient of the metal mask plate for vapor deposition provided by the present invention is small, thus satisfying the vapor deposition requirements; and additionally, the mask plate provided by the present invention has the properties of high hardness and high magnetism.

Description

[0001] technical field [0002] The invention belongs to the technical field of semiconductor elements, and relates to a metal mask, in particular to a metal mask for evaporation made of nickel-iron alloy. [0003] Background technique [0004] The discovery of Invar alloy has attracted the attention and research of scientists from all over the world, which has greatly improved the type, performance and application of Invar alloy. For example, in 1927, Japan first developed Fe-Ni-Co and Fe-Ni-Cr Invar alloys in 1927, and in 1937, Germany A..Kussmann developed Fe-Pt and Fe-Pd Invar alloys; In the 1960s, 4J32 and 4J36 Invar alloys were also developed; after 70 years of development, it was not until the 1970s that Inco Corporation of the United States developed the Incoloy903 alloy that the low-expansion alloy entered the field of high-temperature applications. By the end of the 1980s, The modern low-expansion superalloy series was formed. As a low-expansion alloy, structura...
