Light-receiving device, method for manufacturing the same, and optoelectronic integrated circuit comprising the same

An optoelectronic integrated circuit comprising at least one light-receiving device for receiving light formed on a substrate, wherein the light-receiving device comprises:

• an intrinsic region formed on the substrate;
• a first region formed to a relatively shallow depth in the intrinsic region;
• and
• a second region formed to a relatively deep depth in the intrinsic region and distanced from the first region, the first and second regions being doped with different conductivity types.

A method for manufacturing a light-receiving device, the method comprising:

• preparing a substrate;
• forming an intrinsic region on the substrate;
• and
• forming first and second regions in the intrinsic region to relatively shallow and deep depths, respectively, wherein the first and second regions are distanced from each other and doped with different conductivity types.
