Abstract: An electronic circuit (100) comprises at least one circuit (101) comprising at least one multi-gate functional FET (102) with at least two gates and at least one ESD protection circuit (103) comprising a multi-gate protective FET (104) that is formed partly as an electrical charge carrying reducing transistor. The trigger voltage of the protective FET is less than that of the functional FET. Independent claims are also included for the following: (A) A circuit arrangement as above;and (B) A production process for the above.

Abstract: A method, in an RF-based plasma processing chamber 600, for performing a planarization etch and a recess etch of a first layer on a semiconductor wafer 614. The method includes placing the semiconductor wafer, including a trench formed therein, into the plasma processing chamber. The method also includes depositing the first layer over a surface of the semiconductor and into the trench. There is further included performing the planarization etch to substantially planarize the first layer in the plasma processing chamber, the planarization etch being performed with a first ion density level. Additionally, there is included performing, using the plasma processing chamber, the recess etch on the first layer to recess the first layer within the trench. The recess etch is performed with a second ion density level in the plasma processing chamber, with the second ion density level being higher than the first ion density level.

Abstract: A transistor and method of manufacturing thereof. A gate dielectric and gate are formed over a workpiece, and the source and drain regions of a transistor are recessed. The recesses are filled with a dopant-bearing metal, and a low-temperature anneal process is used to form doped regions within the workpiece adjacent the dopant-bearing metal regions. A transistor having a small effective oxide thickness and a well-controlled junction depth is formed.
