  • Patent number: 11855212
    Abstract: FDSOI device fabrication method is disclosed. The method comprises: disposing a buried oxide layer on the silicon substrate; disposing a SiGe channel on the buried oxide layer, disposing a nitrogen passivation layer on the SiGe channel layer; disposing a metal gate on the nitrogen passivation layer, and attaching sidewalls to sides of the metal gate; and disposing source and drain regions on the nitrogen passivation layer at both sides of the metal gate, wherein the source and drain regions are built in a raised SiGe layer. The stack structure of the SiGe layer and the nitrogen passivation layer forms the gate channel. This stack structure avoids the low stress of the silicon channel in the conventional device. In addition, it prevents the Ge diffusion from the SiGe channel to the gate dielectric in the conventional device. Thereby the invention improves reliability and performance of the device.

  • Publication number: 20160322476
    Abstract: A method of manufacturing a fin field effect transistor is provided. A double spacer protective layer comprising an outer spacer (the first spacer) and an inner spacer (the second spacer) is formed on both sides of the gate, and the thickness of the outer spacer can be adjusted to accurately control the distance between the source/drain ion implantation area and the channel, so as to solve the problem of the hot carrier injection effect caused by the distance being too close between the channel and the source/drain area; in addition, the outer spacers and the inner spacers can be formed by only two film deposition and etching processes without adding a photolithography mask, which can effectively prevent the contact between the gate and the source/drain, so as to substantially reduce the parasitic capacitance.

  • Patent number: 9171731
    Abstract: The invention relates to microelectronic technology and, more specifically, relates to a method of forming a gate with a LELE double pattern. The method adopts an ONO structure (Oxide-SiN-Oxide). The ONO structure is exposed twice, and the advanced patterning film is used as a mask in the processing of polysilicon etching. The ONO structure is used to replace the traditional hardmask of silicon oxide, and the substructure of ODL (Organic Under Layer) which is based on the spin-on, and the middle layer structure of SHB (Si-based hardmask). The method saves cost and improves the process of advanced patterning film as a mask with the nodes in 40 nm and above which is applied to the process with the nodes in 22/20 nm and below. Consequently, the maturity and stability of the process for poly gate with the nodes in 22/20 nm and below are improved.
