Abstract: Methods for gapfilling semiconductor device features, such as high aspect ratio trenches, with amorphous silicon film are provided. First, a substrate having features formed in a first surface thereof is positioned in a processing chamber. A conformal deposition process is then performed to deposit a conformal silicon liner layer on the sidewalls of the features and the exposed first surface of the substrate between the features. A flowable deposition process is then performed to deposit a flowable silicon layer over the conformal silicon liner layer. A curing process is then performed to increase silicon density of the flowable silicon layer. Methods described herein generally improve overall etch selectivity by the conformal silicon deposition and the flowable silicon deposition two-step process to realize seam-free gapfilling between features with high quality amorphous silicon film.

Abstract: Diffusion regions having the same conductivity type are arranged on a side of a second wiring and a side of a third wiring, respectively under a first wiring connected to a signal terminal. Diffusion regions are separated in a whole part or one part of a range in a Y direction. That is, under first wiring, diffusion regions are only formed in parts opposed to diffusion regions formed under the second wiring and third wiring connected to a power supply terminal or a ground terminal, and a diffusion region is not formed in a central part in an X direction. Therefore, terminal capacity of the signal terminal can be reduced without causing ESD resistance to be reduced, in an ESD protection circuit with the signal terminal.

Abstract: The present disclosure relates to a method for bonding semiconductor components. A semiconductor component comprising microbumps on a planar bonding surface is prepared for bonding by applying a photosensitive polymer layer on the bonding surface. The average thickness of the initial polymer layer in between the microbumps is similar to the average height of the microbumps.

Abstract: Double sided versions of several power transistor types are devices that are already known in the literature. Devices built in this configuration are generally required to have a separate driver circuit to control the front and rear control electrodes and provide the gate or base voltage and/or currents for the power switch. This is because there may be of the order of 1000V potential-difference between the frontside and rearside potentials when the transistor is in the off condition—and a single integrated circuit cannot generally sustain this within a single package. The NPN configuration is preferred in this case to benefit from electron conduction for the main power path between the emitters. However, problems arising when using a P-type wafer. The present invention seeks to avoid the use of P-type wafers while still getting the higher conduction performance of NPN operation.
