Abstract

A semiconductor device and manufacturing method therefor, provided with the aims of constraining resin burr formation while having good electric connectivity and joining strength, and LED device, provided with the aim of improving adhesion between silicon resin and leads while having good luminescent characteristics. For these purposes, an organic film is formed through self-assembly by functional organic molecules at surface border regions of outer leads of a QFP. The functional organic molecules consist of a first functional group bonding with metals, a principal chain, and a second functional group inducing hardening in thermosetting resins. The principal chain consists of a glycol chain, or else of a glycol chain and one or more among methylene, fluoromethylene, or siloxane chains. The principal chain also preferably includes one or more among a hydroxyl radical, ketone, thioketone, primary amine, secondary amine, and aromatic compounds.

Claims (6)

1. An organic compound forming a self-assembling film by aligning an extremity of a principal chain on a metal surface, wherein:

the principal chain comprises a N-containing heterocycle containing two or more N atoms,

the N-containing heterocycle comprises one or more compounds selected from the group consisting of imidazole, triazole, tetrazole, oxadiazole, thiadiazole, pyrimidine, pyridazine, pyrazine, and triazine,

the principal chain further comprises, farther from the extremity thereof than the N-containing heterocycle, one or more skeletons selected from the group consisting of an aryl skeleton, a pyrene skeleton, a phenanthrene skeleton, and a fluorene skeleton,

the number of aromatic rings included in the one or more skeletons is from two to six, and

the aryl skeleton is selected from the group consisting of biphenyl, terphenyl, quaterphenyl, quinquiphenyl, and sexiphenyl.
