摘要： A method for bonding at low or room temperature includes steps of surface cleaning and activation by cleaning or etching. The method may also include removing by-products of interface polymerization to prevent a reverse polymerization reaction to allow room temperature chemical bonding of materials such as silicon, silicon nitride and SiO2. The surfaces to be bonded are polished to a high degree of smoothness and planarity. VSE may use reactive ion etching or wet etching to slightly etch the surfaces being bonded. The surface roughness and planarity are not degraded and may be enhanced by the VSE process. The etched surfaces may be rinsed in solutions such as ammonium hydroxide or ammonium fluoride to promote the formation of desired bonding species on the surfaces.

摘要： A method for providing encapsulation of an electronic device which obtains an encapsulating member configured to enclose the electronic device, prepares a surface of the encapsulating member for non-adhesive direct bonding, prepares a surface of a device carrier including the electronic device for non-adhesive direct bonding, and bonds the prepared surface of the encapsulating member to the prepared surface of the device carrier to form an encapsulation of the electronic device. As such, an encapsulated electronic device results which includes the device carrier having a first bonding region encompassing the electronic device, includes the encapsulating member having at least one relief preventing contact between the electronic device and the encapsulating member and having a second bonding region bonded to the first bonding region of the device carrier, and includes a non-adhesive direct bond formed between the first and second bonding regions thereby to form an encapsulation of the electronic device. The encapsulated electronic device can be an electronic or optoelectronic device.

摘要： A process for bonding oxide-free silicon substrate pairs and other substrates at low temperature. This process involves modifying the surface of the silicon wafers to create defect regions, for example by plasma-treating the surface to be bonded with a or boron-containing plasmas such as a B2H6 plasma. The surface defect regions may also be created by ion implantation, preferably using boron. The surfaces may also be amorphized. The treated surfaces are placed together, thus forming an attached pair at room temperature in ambient air. The bonding energy reaches approximately 400 mJ/m2 at room temperature, 900 mJ/m2 at 150° C., and 1800 mJ/m2 at 250° C. The bulk silicon fracture energy of 2500 mJ/m2 was achieved after annealing at 350-400° C. The release of hydrogen from B—H complexes and the subsequent absorption of the hydrogen by the plasma induced modified layers on the bonding surfaces at low temperature is most likely responsible for the enhanced bonding energy.

摘要： A method for bonding at low or room temperature includes steps of surface cleaning and activation by cleaning or etching. One etching process the method may also include removing by-products of interface polymerization to prevent a reverse polymerization reaction to allow room temperature chemical bonding of materials such as silicon, silicon nitride and SiO2. The surfaces to be bonded are polished to a high degree of smoothness and planarity. VSE may use reactive ion etching or wet etching to slightly etch the surfaces being bonded. The surface roughness and planarity are not degraded and may be enhanced by the VSE process. The etched surfaces may be rinsed in solutions such as ammonium hydroxide or ammonium fluoride to promote the formation of desired bonding species on the surfaces.

摘要： A method for providing encapsulation of an electronic device which obtains an encapsulating member configured to enclose the electronic device, prepares a surface of the encapsulating member for non-adhesive direct bonding, prepares a surface of a device carrier including the electronic device for non-adhesive direct bonding, and bonds the prepared surface of the encapsulating member to the prepared surface of the device carrier to form an encapsulation of the electronic device. As such, an encapsulated electronic device results which includes the device carrier having a first bonding region encompassing the electronic device, includes the encapsulating member having at least one relief preventing contact between the electronic device and the encapsulating member and having a second bonding region bonded to the first bonding region of the device carrier, and includes a non-adhesive direct bond formed between the first and second bonding regions thereby to form an encapsulation of the electronic device. The encapsulated electronic device can be an electronic or optoelectronic device.
