    摘要: A semiconductor fabrication process includes forming a gate electrode (112) overlying a gate dielectric (114) overlying a semiconductor substrate (104) of a wafer (101) and a liner dielectric layer (116) including vertical portions (118) adjacent sidewalls of the gate electrode and horizontal portions (117) overlying an upper surface of the semiconductor substrate (104). A spacer (108) is formed adjacent a vertical portion (118) and overlying a horizontal portion (117) of the liner dielectric layer (116). After forming the spacer (108), exposed portions of the liner dielectric layer (116) are removed to form a liner dielectric structure (126) covered by the extension spacer (108). The extension spacer (108) is then etched back to expose or uncover extremities of the liner dielectric structure (126). Prior to etching back the spacer (108), a metal (130) may be sputtered deposited over the wafer (101) preparatory to forming a silicide (134). After the etch back the wafer (101) may be dipped in piranha solution and cleaned with an RF sputter (140) of argon.

    摘要: A method for forming a phase change memory cell (PCM) includes forming a heater for the phase change memory and forming a phase change structure electrically coupled to the heater. The forming a heater includes siliciding a material including silicon to form a silicide structure, wherein the heater includes at least a portion of the silicide structure. The phase change structure exhibits a first resistive value when in a first phase state and exhibits a second resistive value when in a second phase state. The silicide structure produces heat when current flows through the silicide structure for changing the phase state of the phase change structure.

    摘要: Forming structures such as fins in a semiconductor layer according to a pattern formed by oxidizing a sidewall of a layer of oxidizable material. In one embodiment, source/drain pattern structures and a fin pattern structures are patterned in the oxidizable layer. The fin pattern structure is then masked from an oxidation process that grows oxide on the sidewalls of the channel pattern structure and the top surface of the source/drain pattern structures. The remaining oxidizable material of the channel pattern structure is subsequently removed leaving a hole between two portions of the oxide layer. These two portions are used in one embodiment as a mask for patterning the semiconductor layer to form two fins. This patterning also leaves the source/drain structures connected to the fins.

    摘要: A semiconductor fabrication process includes forming a silicon fin overlying a substrate. A gate dielectric is formed on primary faces of the fin. A gate electrode is formed over at least two faces of the fin. Dielectric spacers are then selectively formed in close proximity and confined to the sidewalls of the gate electrode thereby leaving a majority of the primary fin faces exposed. Thereafter a silicide is formed on the primary fin faces. The forming of the gate electrode in one embodiment includes depositing polysilicon over the fin and substrate, depositing a capping layer over the polysilicon, patterning photoresist over the capping layer and etching through the capping layer and the polysilicon with the patterned photoresist in place wherein the etching produces a polysilicon width that is less than a width of the capping layer to create voids under the capping layer adjacent sidewalls of the polysilicon where the confined spacers can be formed.
