Abstract: 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.

Abstract: A semiconductor device and method of fabricating the device. An emitter region is formed self centered and self aligned symmetrically with a base region. Using frontside processing techniques, a collector is formed symmetrically self-aligned with the base region and the emitter region. The collector region may be further formed self-centered with the base region using backside processing techniques. The self-aligned and self-centered symmetric structure virtually eliminates parasitic elements in the device significantly improving the device performance. The device is scalable on the order of approximately 0.1 microns. The method also provides reproduceability and repeatability of device characteristics necessary for commercial manufacture of the symmetric device.

Abstract: A heterojunction bipolar transistor structure grown with organometallic vapor phase epitaxy (OVMPE) which uses zinc as the base dopant. The HBT structure has eight layers grown on a substrate, including n-type doped first, second, third, fifth, sixth, seventh, and eighth layers and a p-type zinc doped fourth layer. The first layer is a thicker, moderately doped n-type layer compared to the thinner, higher doped n-type second layer. The seventh layer is a thicker, moderately doped n-type layer compared to the thinner, higher doped n-type eighth layer. In addition, some or perhaps all of the layers have a high V/III ratio of 10-100 used to increase the gallium vacancies and reduce the diffusion of zinc from the base layer. Further, annealing of the structure is performed during growth to minimize gallium interstitials and to inhibit the diffusion of zinc.
