摘要:
An object is to reduce leakage current and parasitic capacitance of a transistor used for an LSI, a CPU, or a memory. A semiconductor integrated circuit included in an LSI, a CPU, or a memory is manufactured using the transistor which is formed using an oxide semiconductor which is an intrinsic or substantially intrinsic semiconductor obtained by removal of impurities which serve as electron donors (donors) from the oxide semiconductor and has larger energy gap than a silicon semiconductor, and is formed over a semiconductor substrate. With the transistor which is formed over the semiconductor substrate and includes the highly purified oxide semiconductor layer with sufficiently reduced hydrogen concentration, a semiconductor device whose power consumption due to leakage current is low can be realized.

Methods and structures are described for reducing leakage currents in semiconductor memory storage cells. Vertically oriented nanorods may be used in the channel region of an access transistor. The nanorod diameter can be made small enough to cause an increase in the electronic band gap energy in the channel region of the access transistor, which may serve to limit channel leakage currents in its off-state. In various embodiments, the access transistor may be electrically coupled to a double-sided capacitor. Memory devices according to embodiments of the invention, and systems including such devices are also disclosed.

摘要:
The invention includes a semiconductor construction having a pair of channel regions that have sub-regions doped with indium and surrounded by boron. A pair of transistor constructions are located over the channel regions and are separated by an isolation region. The transistors have gates that are wider than the underlying sub-regions. The invention also includes a semiconductor construction that has transistor constructions with insulative spacers along gate sidewalls. Each transistor construction is between a pair source/drain regions that extend beneath the spacers. A source/drain extension extends the source/drain region farther beneath the transistor constructions on only one side of each of the transistor constructions. The invention also includes methods of forming semiconductor constructions.
