Problems solved by technology

However, the polymer film obtained by such means is brittle and easy to crack, so the functional elements formed on the surface of the polymer film are often damaged when they are peeled off from the inorganic substrate.
In particular, it is very difficult to peel a large-area film from an inorganic substrate, and it is almost impossible to obtain an industrially feasible yield

manufacture example 1

[0136] [Manufacturing Example 1 (Manufacture of Polyamic Acid Solution A)]

[0137] After carrying out nitrogen replacement in the reaction vessel equipped with nitrogen inlet pipe, thermometer and stirring rod, add 223 parts by mass of 5-amino-2-(p-aminophenyl) benzoxazole (DAMBO), N in the above-mentioned reaction vessel, 4416 parts by mass of N-dimethylacetamide, and completely dissolved. Next, together with 217 parts by mass of pyromellitic dianhydride (PMDA), SNOWTEX (DMAC-ST30, Nissan Chemical Co. Industrial production), and make colloidal silicon dioxide relative to the total amount of the polymer solid content in the polyamic acid solution A 0.7% by mass, carry out heating and stirring for 24 hours at a reaction temperature of 25° C., to obtain a brown viscous poly Amic acid solution A.

Abstract

A laminate comprising a heat-resistant polymer film, an inorganic substrate, and a polyamine compound layer formed using a polyamine compound, wherein the polyamine compound layer is formed between the heat-resistant polymer film and the inorganic substrate.

Description

technical field [0001] The present invention relates to a laminate and a method for producing the laminate. Background technique [0002] In recent years, for the purpose of weight reduction, miniaturization / thinning, and flexibility of functional elements such as semiconductor elements, MEMS elements, and display elements, technology development for forming these elements on polymer films is actively progressing. That is, as the base material of electronic components such as information communication equipment (broadcasting equipment, mobile radio, mobile communication equipment, etc.), radar, high-speed information processing equipment, etc., currently, heat-resistant materials that can cope with high signal levels of information communication equipment are used. However, since ceramics are not flexible and difficult to thin, there is a disadvantage that the applicable field is limited, so polymer films are recently used as substrates. [0003] When forming functional ele...
