Item type:Item, FIELD EFFECT TRANSISTOR STRUCTURE(2017-11-02)Chun-Yen ChangA field effect transistor (FET) structure includes a substrate, an internal gate, an insulation layer, a semiconductor strip, a gate dielectric insulator, and a gate conductor. The internal gate includes a floor portion located on the substrate and a wall portion extending from the floor portion. The insulation layer is located on the floor portion of the internal gate. The semiconductor strip is located on the wall portion and a portion of the insulation layer, and the semiconductor strip includes source/drain regions and a channel region adjacent to the source/drain regions. The gate dielectric insulator is located on the channel region. The gate conductor is located on the gate dielectric insulator.Item type:Item, SILICON-CONTROLLED RECTIFIER AND AN ESD CLAMP CIRCUIT(2017-03-16) ;Chun-Yen Chang ;Shiang-Shiou Yen ;Shao-Chin ChangChe-Wei ChiangA silicon-controlled rectifier (SCR) includes a first-type field, a second-type first field and a second-type second field disconnectedly formed in a first-type well; an entire first-type doped region formed within the first-type field; a segmented second-type doped region formed within the second-type first field; and a segmented first-type doped region formed within the second-type second field.
