  • Publication number: 20200098580
    Abstract: The present disclosure relates to integrated circuit device manufacturing processes. A self-aligned double patterning method is provided. In the method, a lithography process for line cut that determines the locations of line termini is performed after forming a spacer layer alongside the mandrel and prior to stripping the mandrel. The lithographic mask for the line cut is aligned to the mandrel and the spacer layer using a mark made of the mandrel material and the spacer material. Compared to the previous approach where the line cut process is performed after the mandrel removal, in the disclosed approach, the line termini mask is made of the mandrel material and the spacer material, and is more distinguishable compared to a mark made of just the spacer material. Thereby, the methods provide robust photo alignment signal for the line cut photolithography and precise positioning of the line termini mask.

  • Patent number: 10522429
    Abstract: A method of manufacturing a semiconductor device is provided. The method includes the following operations. (a) A substrate is patterned. (b) A polymer layer is formed on the patterned substrate. (c) The polymer layer is patterned. Steps (a), (b) and (c) are repeated alternatingly. An intensity of an emission light generated by a reaction of a plasma and a product produced in steps (a), (b) and (c) is detected. An endpoint in patterning the substrate is determined according to the intensity of the emission light generated by the reaction of the plasma and the product produced in only one step of steps (a), (b) and (c). A sampling rate of the intensity is ranged from 1 pt/20 ms to 1 pt/100 ms. A smooth function is used to process the intensity of the emission light generated by the reaction of the plasma and the product.

  • Publication number: 20190367358
    Abstract: A semiconductor arrangement and methods of formation are provided. The semiconductor arrangement includes a micro-electro mechanical system (MEMS). A via opening is formed through a substrate, first dielectric layer and a first plug of the MEMS.
