Either angled nitrogen implantation or nitride spacers is used to create a “shadow effect” or area, which limits the nitrogen dose close to the edges of the active area. The reduction of nitrogen dose leads to an increased gate oxide thickness at the active area (AA) adjacent to the shallow trench, increases the threshold of the parasitic corner device and reduces sub Vt (threshold voltage) and junction leakage.

Abstract: Disclosed is a method of manufacturing a MOS transistor having an enhanced reliability. A passivation layer is formed on a gate electrode and on a substrate to prevent a generation of a recess on the substrate. After a mask pattern is formed on the substrate for masking a portion of the substrate, impurities are implanted into an exposed portion of the substrate to form source and drain regions. The substrate is rinsed so that the passivation layer or a recess-prevention layer is substantially entirely or partially removed while the mask pattern is substantially completely removed, thereby forming the MOS transistor. Therefore, the generation of the recess in the source and drain region of the substrate can be prevented due to the passivation layer during rinsing of the substrate.

Abstract: A magnetoresistive (MR) sensor can be shaped using ion beam irradiation and/or implantation through a mask introduced between a MR structure and an ion source. The mask covers selected portions of the MR structure to define the track width of the sensor. Ion irradiation and/or implantation reduces the magnetoresistance of the unmasked portions while leaving the masked portion substantially unaltered. The mask can be a photoresist mask, an electron beam resist mask, or a stencil mask. Alternatively the mask may be part of a projection ion beam system. Track width resolution is determined at the mask production step. The edges of the sensor can be defined by a highly collimated ion beam producing an extremely straight transition edge, which reduces sensor noise and improves sensor track width control. Improved hard bias layers that directly abut the sensor may be used to achieve a suitable stability. A variety of longitudinal bias schemes are compatible with ion beam patterning.

Abstract: At the surface of a substrate a gate oxide layer is produced and is given a dual thickness. A first oxide layer is produced over the surface of a substrate by thermal oxidation and is covered by a mask layer defining suitably located openings. A material accelerating or retarding the oxidation of the substrate is ion implanted through the first oxide layer in the openings, after which the mask is removed and the thermal oxidation is continued over the now exposed total surface of the first oxide layer. The material used for ion implanting can be an oxidation rate promoting material such as chloride and bromine. The manufacturing method is simple and adds little to presently used process flows for fabricating MOS devices. The dual thickness of the gate oxide gives the manufactured MOS device a low level of total noise generated when using the device for instance in RF-circuits.

In still another implementation, both the height of the features and angle of the implant are varied to set the spacing for different doped regions.

Abstract: A method for manufacturing an electronic device is provided. In one example of the method, the method prevents deformation of a resist mask caused by the irradiation of exposure light. The resist mask has a resist as an opaque element, and can afford mask patterns undergoing little change even with an increase in the number of wafers subjected to exposure processing.

The deformation of a resist opaque pattern in a photomask is prevented. The dimensional accuracy of patterns transferred onto a Si wafer is improved in repeated use of the photomask.
