Patent ID: 6924169

Claim:
A manufacturing method for manufacturing an image detector, the method comprising: depositing a sacrificial layer on an upper section of a substrate; forming a pattern for the sacrificial layer, by performing a patterning process using a first etching mask, to produce a sacrificial layer product; depositing a first silicon nitride layer on the whole surface of the sacrificial layer product; forming a pattern for the first silicon nitride layer, by performing a patterning process using a second etching mask, to produce a first silicon nitride layer product; depositing a vanadium oxide layer on the whole surface of the first silicon nitride layer product; forming a pattern for the vanadium oxide layer, by performing a patterning process using a third etching mask, to produce a vanadium oxide layer product; depositing a conductive layer on the whole surface of the vanadium oxide layer product; forming a pattern for the conductive layer, by performing a patterning process using a fourth etching mask, to produce a conducting layer product; depositing a second silicon nitride layer on the whole surface of the conductive layer product; forming a pattern for the second silicon nitride layer, by performing a patterning process using a fifth etching mask, to produce a second silicon nitride layer product; depositing a third silicon nitride layer on the whole surface of the second silicon nitride layer product; forming a pattern for a side wall space, by performing a patterning process using a sixth etching mask, to produce a side wall space product; and aligning, after the sacrificial layer is removed from the side wall space product using a seventh etching mask.
