摘要:
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.

A method for insertion bonding and a device thus obtained are disclosed. In one aspect, the device includes a first substrate having a front main surface and at least one protrusion at the front main surface. The device includes a second substrate having a front main surface and at least one hole extending from the front main surface into the second substrate. The protrusion of the first substrate is inserted into the hole of the second substrate. The hole is formed in a shape wherein the width is reduced in the depth direction and wherein the width of at least a part of the hole is smaller than the width of the protrusion at the location of the metal portion thereof. The protrusion is deformed during insertion thereof in the hole to provide a bond between the part of the hole and the metal portion.

A method of bonding two elements such as wafers used in microelectronics applications is disclosed. One inventive aspect relates to a method for bonding comprising producing on a first main surface of a first element a first solder ball, producing on a first main surface of a second element a second solder ball, providing contact between the first solder ball and the second solder ball, bonding the first element and the second element by applying a reflow act whereby the solder balls melt and form a joined solder ball structure. Prior to the bonding, the first solder ball is laterally embedded in a nonconductive material, such that the upper part of the first solder ball is not covered by the non-conductive material. Devices related to such methods are also disclosed.

The present invention is related to an image sensor packaging technique based on a Ball Grid Array (BGA) IC packaging technique, further referred to as image sensor ball grid array (ISBGA). A transparent cover is attached to a semiconductor substrate. Depending on the method of attaching the cover to the substrate a hermetic or non-hermitic sealing is obtained. The obtained structure can be connected trough wire-bonding or flip chip connection.

The present invention provides a method of transfer of a first planar substrate with two major surfaces to a second substrate, comprising the steps of: forming the first planar substrate, attaching one of the major surfaces of the first planar substrate to a carrier by means of a release layer; attaching the other major surface of the first substrate to the second substrate with a curable polymer adhesive layer; partly curing the polymer adhesive layer, disconnecting the release layer from the first substrate to separate the first substrate from the camer, followed by coing the polymer adhesive layer.
