Abstract:
1. A light detection device comprising: a silicon substrate; a first conductive pattern formed in a top surface of the silicon substrate using dopants provided into the silicon substrate, the first conductive pattern having a top surface; an insulating pattern on the top surface of the silicon substrate and on a first portion of the top surface of the first conductive pattern, the insulating pattern having an opening exposing a second portion of the top surface of the first conductive pattern; a light absorbing layer filling the opening of the insulating pattern, the light absorbing layer being formed on the second portion of the top surface of the first conductive pattern, the light absorbing layer having a top surface disposed at a height substantially higher than a height of a top surface of the insulating pattern; a second conductive pattern on the light absorbing layer; a first connecting terminal electrically connected to the first conductive pattern; and
