  • Patent number: 9583356
    Abstract: A method for forming a semiconductor device structure is provided. The semiconductor device structure includes forming a film over a substrate. The semiconductor device structure includes forming a first mask layer over the film. The semiconductor device structure includes forming a second mask layer over the first mask layer. The second mask layer exposes a first portion of the first mask layer. The semiconductor device structure includes performing a plasma etching and deposition process to remove the first portion of the first mask layer and to form a protection layer over a first sidewall of the second mask layer. The first mask layer exposes a second portion of the film after the plasma etching and deposition process. The semiconductor device structure includes removing the second portion using the first mask layer and the second mask layer as an etching mask.

  • Publication number: 20160225813
    Abstract: Some embodiments of the present disclosure provide a back side illuminated (BSI) image sensor. The BSI image sensor includes a semiconductive substrate, a deep trench isolation (DTI) at a back side of the semiconductive substrate, and a dielectric layer. the dielectric layer includes a top portion over the back side, and a side portion lined to a sidewall of the DTI. The BSI image sensor includes a planarization stop layer disposed conformally on top of the dielectric layer. The planarization stop layer includes a top section on the top portion, a side section lined against the side portion, and a first transmittance. The BSI image sensor includes a low-transparent material inside the DTI, and the low-transparent material includes a second transmittance. The second transmittance is lower than the first transmittance.

  • Patent number: 9040317
    Abstract: A method includes performing a patterning step on a layer using a process gas. When the patterning step is performed, a signal strength is monitored, wherein the signal strength is from an emission spectrum of a compound generated from the patterning step. The compound includes an element in the patterned layer. At a time the signal strength is reduced to a pre-determined threshold value, the patterning step is stopped.
