Slim optical pickup
First Claim
1. A slim optical pickup for recording and reproducing data to and from an optical disc, the slim optical pickup comprising:
- a substrate including a light source that generates light, an optical device that irradiates light onto the optical disc, a photodetector that receives a light beam reflected by the optical disc, and a plurality of first bonding pads;
a heat sink attached to a surface of the substrate; and
a supporting unit that includes a plurality of second bonding pads, wherein the supporting unit and the light source are disposed on an opposite surface of the substrate to which the heat sink is attached, said supporting unit having an opening through which the light source and photodetector are exposed.

Abstract
A slim optical pickup in which a leaf spring is combined with an upper surface of a semiconductor substrate, which is a silicon optical bench (SiOB) monolithically manufactured with a photodetector. The slim optical pickup has a substrate including a light source for generating a light beam, an optical element to irradiate light to an optical disc, a photodetector for receiving a light beam reflected by the optical disc, and a plurality of first bonding pads; a heat sink attached to the surface of the substrate; and a supporting means having a plurality of second bonding pads formed on an inner side of an array of the plurality of the first bonding pads on the substrate.
