BIOCOMPATIBLE PACKAGING
First Claim
1. An implantable bio-medical device, the device comprising a component present on a substrate, the component and the substrate hermetically sealed within an encapsulation, the encapsulation comprising a continuous layer of biocompatible material around all outer surfaces of the component and the substrate, the substrate comprising at least one sloped side wall between a top surface and a bottom surface of the substrate.

Abstract
A method is disclosed for packaging a device, e.g., for bio-medical applications. In one aspect, the method includes obtaining a component on a substrate and separating the component and a first part of the substrate from a second part of the substrate using at least one physical process inducing at least one sloped side wall on the first part of the substrate. The method also includes providing an encapsulation for the chip. The resulting packaged chip advantageously has a good step coverage resulting in a good hermeticity, less sharp edges resulting in a reduced risk of damaging or infection after implantation and has a relatively small packaged volume compared to conventional big box packaging techniques.
