摘要： A chip includes a CMOS structure having a bulk device disposed in a first region of a semiconductor substrate in conductive communication with an underlying bulk region of the substrate, the first region and the bulk region having a first crystal orientation. A SOI device is disposed in a semiconductor-on-insulator (“SOI”) layer separated from the bulk region of the substrate by a buried dielectric layer, the SOI layer having a different crystal orientation from the first crystal orientation. In one example, the bulk device includes a p-type field effect transistor (“PFET”) and the SOI device includes an n-type field effect transistor (“NFET”) device. Alternatively, the bulk device can include an NFET and the SOI device can include a PFET. When the SOI device has a gate conductor in conductive communication with a gate conductor of the bulk device, charging damage can occur to the SOI device, except for the presence of diodes in reverse-biased conductive communication with the bulk region. The diodes are operable to conduct a discharge current to the bulk region when either a voltage on the gate conductor or a voltage on the source or drain region of the SOI device exceeds a diode's breakdown voltage.

摘要： A silicon nitride spacer material for use in forming a PFET device and a method for making the spacer includes the use of a dual-frequency plasma enhanced CVD process wherein the temperature is in the range depositing a silicon nitride layer by means of a low-temperature dual-frequency plasma enhanced CVD process, at a temperature in the range 400° C. to 550° C. The process pressure is in the range 2 Torr to 5 Torr. The low frequency power is in the range 0 W to 50 W, and the high frequency power is in the range 90 W to 110 W. The precursor gases of silane, ammonia and nitrogen flow at flow rates in the ratio 240:3200:4000 sccm. The use of the silicon nitride spacer of the invention to form a PFET device having a dual spacer results in a 10%-15% performance improvement compared to a similar PFET device having a silicon nitride spacer formed by a RTCVD process.

摘要： Methods of forming a strained Si-containing hybrid substrate are provided as well as the strained Si-containing hybrid substrate formed by the methods. In the methods of the present invention, a strained Si layer is formed overlying a regrown semiconductor material, a second semiconducting layer, or both. In accordance with the present invention, the strained Si layer has the same crystallographic orientation as either the regrown semiconductor layer or the second semiconducting layer. The methods provide a hybrid substrate in which at least one of the device layers includes strained Si.
