The N/sup +/ region in between T/sub 1/ and T/sub 2/ is kept floating. This structure can confine the kink effect to the upper transistor T/sub 2/ and thus successfully keeps the lower transistor T/sub 1/ from undergoing pinch-off, impact ionization, and the kink effect. If the channel length of T/sub 1/ is longer than that of T/sub 2/, then T/sub 1/ will dominate the overall output characteristics of the device. As a result, the kink effect is eliminated from the overall output characteristics. This structure can also confine the parasitic bipolar effect only to the upper transistor T/sub 2/. Since the base hole current of T/sub 2/ will recombine in the common N/sup +/ region, it cannot reach the base region of the lower transistor T/sub 1/. Results of measurements and simulation are given.<<ETX>>","PeriodicalId":344373,"journal":{"name":"1990 IEEE SOS/SOI Technology Conference.

The transistors were fabricated in SIMOX material with an estimated film thickness of 0.2 mu m, a buried insulator thickness of 0.4 mu m, and a gate oxide thickness of 20 nm. The measured threshold voltage of the 1 mu m n-channel transistor was 1.08 V and the subthreshold slope 86 mV/decade. The snapback voltage was defined as the maximum drain voltage at which the transistor turns off, when swept in the direction of decreasing gate voltage. Excellent agreement has been achieved over a range of transistor gate lengths down to 0.5 mu m. Two-dimensional device simulation can be used to determine the optimum transistor structure by considering the factors associated with engineering both the source and drain regions with a view to maximizing the breakdown voltage.<<ETX>>","PeriodicalId":344373,"journal":{"name":"1990 IEEE SOS/SOI Technology Conference.

The holding voltage is a function of channel length as predicted by the model, and good agreement with experimental data is obtained for a recombination lifetime of 0.7 ns and k=0.015. The model also predicts that if the lifetime is reduced to 0.4 ns the holding voltage is only slightly increased for short-channel devices suggesting that decreasing the lifetime in the body by external means (e.g., gold doping) has little effect for small gate lengths. In addition the model can also predict the temperature dependence of the holding voltage.<<ETX>>","PeriodicalId":344373,"journal":{"name":"1990 IEEE SOS/SOI Technology Conference.

In an effort to gain further understanding of these defects, the authors investigated the effect of constant bias stressing on SIMOX buried oxides.

For low implant dose material, enhanced electron injection from the film/buried oxide interface is seen. For this material, there is also a net negative trapped charge and generation of interface traps at both buried oxide interfaces.

It forms a solid basis for further optimization of specific thin-film properties. It is based on a local semiempirical carrier mobility model. The model can include all possible scattering mechanisms. It can also be used for low temperature ranges, where Coulomb scattering is dominant. A satisfactory and well-proved polynomial approximation allows an implementation of the local character of the carrier mobility model in a circuit simulation model. With a hyperbolical tangent dependence of the threshold voltage on the back gate voltage, the basis is formed for an accurate model for thin-film SOI devices.<<ETX>>","PeriodicalId":344373,"journal":{"name":"1990 IEEE SOS/SOI Technology Conference.

Interfaces prepared at temperatures in the range 900-1100 degrees c exhibited U-shaped interface state densities. Si/Si samples were prepared using a hydrophilizing surface treatment before wafer bonding. At the same annealing temperatures, the interface state densities of the bonded Si/Si interfaces were in the range 10/sup 11/-10/sup 13/ cm/sup -2/ eV/sup -1/. Si/Si interfaces are found to be very sensitive to prebond chemical treatment, while Si/SiO/sub 2/ interfaces are not.
