Abstract:
A method for manufacturing a semiconductor device according to an embodiment includes making intermediate structural bodies. The shape of an upper and a lower portion of the body are different from each other. The rotational symmetry of the electrode corresponds to that of the semiconductor body. The method includes arranging the intermediate structural bodies to be separated from each other on a tray and vibrating the tray. By causing one of these portions to engage with a recess in an upper surface of a tray the bodies are self-assembled on the tray. The one portion is specially shaped to engage with the recess, while the opposite side does not to engage with the recess. The method includes forming an external electrode connected to an electrode of the intermediate structural body with extends laterally from the body.
Abstract:
A method for manufacturing a semiconductor device according to an embodiment includes making intermediate structural bodies. A configuration of an upper portion of the intermediate structural body and a configuration of a lower portion of it are different from each other. The method includes arranging the intermediate structural bodies to be separated from each other by causing one portion selected from the upper portion and the lower portion to engage with a recess multiply made in an upper surface of a tray by causing the intermediate structural bodies to tumble on the tray. The one portion is configured to engage with the recess. The other portion selected from the upper portion and the lower portion is configured not to engage with the recess. The method includes forming an external electrode connected to an electrode of the intermediate structural body.
Abstract:
A first layer of first vertical light emitting diodes (VLEDs) is printed on a conductor surface. A first transparent conductor layer is deposited over the first VLEDs to electrically contact top electrodes of the first VLEDs. A second layer of second VLEDs is printed on the first transparent conductor layer. Since the VLEDs are printed as an ink, the second VLEDs are not vertically aligned with the first VLEDs, so light from the first VLEDs is not substantially blocked by the second VLEDs when the VLEDs are turned on. A second transparent conductor layer is deposited over the second VLEDs to electrically contact top electrodes of the second VLEDs. By this structure, the first VLEDs are connected in parallel, the second VLEDs are connected in parallel, and the first layer of first VLEDs and the second layer of second VLEDs are connected in series by the first transparent conductor layer.
Abstract:
A Microelectromechanical System (MEMS) microphone includes a printed circuit board, a MEMS die, and an integrated circuit. The MEMS die disposed on a top surface of the printed circuit board. The integrated circuit is disposed at least partially within the printed circuit board and produces at least one output signal. The at least one output signal of the integrated circuit is routed directly into at least one conductor to access pads at the printed circuit board. The access pads are disposed on a bottom surface of the printed circuit board that is opposite the top surface. The integrated circuit includes conductive pads and an interface layer is disposed between the conductive pads of the integrated circuit and the printed circuit board.
Abstract:
A method of processing a substrate (1) that displays out-gassing when placed in a vacuum comprises placing the substrate in a vacuum and performing an out-gassing treatment by heating the substrate (1) to a temperature T1 and removing gaseous contamination emitted from the substrate (1) until the out-gassing rate is determined by the diffusion of the substrate's con¬ tamination and thus essentially a steady state has been established. Afterwards, the temperature is lowered to a temperature T2 at which the diffusion rate of the substrate's contamination is lower than at T1. The substrate (1) is further processed at said temperature T2 until the substrate (1) has been covered with a film (16) comprising a metal.
Abstract:
Disclosed are semiconductor die structures that enable a die having a vertical power device to be packaged in a wafer-level chip scale package where the current-conducting terminals are present at one surface of the die, and where the device has very low on-state resistance. In an exemplary embodiment, a trench and an aperture are formed in a backside of a die, with the aperture contacting a conductive region at the top surface of the die. A conductive layer and/or a conductive body may be disposed on the trench and aperture to electrically couple the backside current-conducting electrode of the device to the conductive region. Also disclosed are packages and systems using a die with a die structure according to the invention, and methods of making dice with a die structure according to the invention.
