Abstract: A novel additive for recycling thermoset materials, its related recyclable thermoset composition and its application are disclosed. Specifically, the composition of the additive comprises at least one copolymer that has at least one carbamate group, at least one carbonate group and/or at least one urea group, and a number-average molecular weight of the copolymer is between 100 and 50,000 Da.

Abstract: A method of fabricating a salicided MOS and a one-sided salicided MOS device on a semiconductor substrate. A conformal oxide layer and an organic layer are sequentially formed on first and second MOS devices and the substrate. The first MOS has a first gate structure, a first spacer and first and second doped regions. The second MOS has a second gate structure, a second spacer and third and fourth doped regions. Anisotropic etching is performed to remove part of the organic layer until the oxide layer on the first and the second gate structures is exposed, wherein a remaining organic layer is left above the substrate. The oxide layer on the first and the second gate structures is removed. The remaining organic layer is removed. The oxide layer on the first, second, and third doped regions is removed. Thus, a silicide layer cannot form on the fourth doped region.

Abstract: The present invention is CMOS image sensor and its method of fabrication. This invention provides an efficient structure to improve the quantum efficiency of a CMOS image sensor with borderless contact. The image sensor comprises a N-well/P-substrate type photodiode with borderless contact and dielectric structure covering the photodiode region. The dielectric structure is located between the photodiode and the interlevel dielectric (ILD) and is used as a buffer layer for the borderless contact. The method of fabricating a high performance photodiode comprises forming a photodiode in the n-well region of a shallow trench, and embedding a dielectric material between the ILD oxide and the photodiode having a refraction index higher than the ILD oxide.
