摘要： Embodiments are directed to a method for minimizing electrostatic charges in a semiconductor substrate. The method includes depositing photoresist on a semiconductor substrate to form a photoresist layer on the semiconductor substrate. The photoresist layer is exposed to radiation. The photoresist layer is developed using a developer solution. The semiconductor substrate is cleaned with a first cleaning liquid to wash the developer solution from the photoresist layer. A tetramethylammonium hydroxide (TMAH) solution is applied to the semiconductor substrate to reduce charges accumulated in the semiconductor substrate.

摘要： A first photoresist pattern and a second photoresist pattern are formed over a substrate. The first photoresist pattern is separated from the second photoresist pattern by a gap. A chemical mixture is coated on the first and second photoresist patterns. The chemical mixture contains a chemical material and surfactant particles mixed into the chemical material. The chemical mixture fills the gap. A baking process is performed on the first and second photoresist patterns, the baking process causing the gap to shrink. At least some surfactant particles are disposed at sidewall boundaries of the gap. A developing process is performed on the first and second photoresist patterns. The developing process removes the chemical mixture in the gap and over the photoresist patterns. The surfactant particles disposed at sidewall boundaries of the gap reduce a capillary effect during the developing process.

摘要： Various examples of a technique for forming a pattern for substrate fabrication are disclosed herein. In an example, a method includes receiving a substrate. A patterned resist is formed on the substrate and has a trench defined therein. A dielectric is deposited on the patterned resist and within the trench such that the dielectric narrows a width of the trench to further define the trench. A fabrication process is performed on a region of the substrate underlying the trench defined by the dielectric.

摘要： Implementations of the disclosure provide a method of fabricating an image sensor device. The method includes forming first trenches in a first photoresist layer using a first photomask having a first pattern to expose a first surface of a substrate, directing ions into the exposed first substrate through the first trenches to form first isolation regions in the substrate, removing the first photoresist layer, forming second trenches in a second photoresist layer using a second photomask having a second pattern to expose a second surface of the substrate, the second pattern being shifted diagonally from the first pattern by half mask pitch, directing ions into the exposed second surface through the second trenches to form second isolation regions in the substrate, the first and second isolation regions being alternatingly disposed in the substrate, and the first and second isolation regions defining pixel regions therebetween, and removing the second photoresist layer.
