    摘要: The present disclosure relates to a method and composition to limit crystalline defects introduced in a semiconductor device during ion implantation. A high-temperature low dosage implant is performed utilizing a tri-layer photoresist which maintains the crystalline structure of the semiconductor device while limiting defect formation within the semiconductor device. The tri-layer photoresist comprises a layer of spin-on carbon deposited onto a substrate, a layer of silicon containing hard-mask formed above the layer of spin-on carbon, and a layer of photoresist formed above the layer of silicon containing hard-mask. A pattern formed in the layer of photoresist is sequentially transferred to the silicon containing hard-mask, then to the spin-on carbon, and defines an area of the substrate to be selectively implanted with ions.

    摘要: Methods are disclosed herein for determining the laser beam size and the scan pattern of laser annealing when fabricating backside illumination (BSI) CMOS image sensors to keep dark-mode stripe patterns corresponding to laser scan boundary effects from occurring within the sensor array regions of the image sensors. Each CMOS image sensor has a sensor array region and a periphery circuit. The methods determines a size of the laser beam from a length of the sensor array region and a length of the periphery circuit so that the laser beam covers an integer number of the sensor array region for at least one alignment of the laser beam on the array of BSI image sensors. The methods further determines a scan pattern so that the boundary of the laser beam does not overlap the sensor array regions during the laser annealing, but only overlaps the periphery circuits.

    摘要: A novel method for forming electrodes in the fabrication of an MIM (metal-insulator-metal) capacitor, is disclosed. The method improves MIM capacitor performance by preventing plasma-induced damage to a dielectric layer during deposition of a top electrode on the dielectric layer, as well as by reducing or preventing the formation of an interfacial layer between the dielectric layer and the electrode or electrodes, in fabrication of the MIM capacitor. The method typically includes the patterning of crown-type capacitor openings in a substrate; depositing a bottom electrode in each of the crown openings; subjecting the bottom electrode to a rapid thermal processing (RTP) or furnace anneal step; depositing a dielectric layer on the annealed bottom electrode; depositing a top electrode on the dielectric layer using a plasma-free CVD (chemical vapor deposition) or ALD (atomic layer deposition) process; and patterning the top electrode of each MIM capacitor.

    摘要: Semiconductor devices, and methods of fabricating, having ammonia-treated polysilicon devices are provided. A substrate is provided upon which a polysilicon layer is formed. The polysilicon layer is treated with ammonia. Thereafter, portions of the polysilicon layer may be oxidized, forming poly-oxide regions. The poly-oxide regions may be used, for example, to form the poly-oxide layer of a split-gate transistor. The ammonia treatment reduces the tendency of the polysilicon to oxidize along the grain boundaries, thereby allowing smaller designs to be fabricated without bridging occurring between polysilicon structures.
