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 bonding pads;
a heat sink attached to a surface of the substrate; and
a supporting unit that includes a plurality of second bonding pads and is disposed on an opposite surface of the substrate to which the heat sink is attached.

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.
