Island isolated, fully depleted n-channel MOSFETs of various widths and lengths fabricated in different thicknesses of SIMOX (separation by implantation of oxygen) SOI films were used in this experiment. The nature of the charge generation and the charge accumulation processes at the interface between the Si film and the SIMOX buried oxide is complicated and unknown. Hence it is difficult to model analytically the first transient. The problem can be simplified by studying the second, smaller transient which is observed when the back side of the Si film is further accumulated by increasing the negative substrate bias. Both the first and the second transient were studied as functions of the bias conditions and device geometry.<<ETX>>","PeriodicalId":344373,"journal":{"name":"1990 IEEE SOS/SOI Technology Conference.

The authors (1990) proposed an improved HVTFT device structure with an independently-biased metal field plate (FP) overlapping the entire offset region. The new FP-HVTFT eliminates the expensive lightly-doped-drain implant required in the conventional offset-gate HVTFTs and the current-pinching effects commonly observed in conventional offset-gate polysilicon HVTFTs. The authors report the effects of offset length (L/sub off/) on the new FP-HVTFTs, as the device characteristics of the conventional offset-gate polysilicon HVTFTs are known to be very sensitive to L/sub off/, and L/sub off/ is set by the alignment between two masking layers in actual device fabrication. The feasibility is reported of using the field-plate device as a low-voltage TFT for reducing the off-state leakage current.<<ETX>>","PeriodicalId":344373,"journal":{"name":"1990 IEEE SOS/SOI Technology Conference.

Devices were fabricated using n-type epitaxially deposited silicon on double-solid-phase-epitaxy (DSPE) improved SOS. The total thickness of the first and second silicon epi-layers was nominally 2.0 mu m. Devices were fabricated using three different laser fluences for the emitter anneal.

The localization of interface defects near the drain was studied. It is found that, in general, front channel transistors are very tolerant to aging. Once the LDD spacer was optimized, the degradation subsequent to 150 h of stress was almost insignificant. No degradation of the back interface occurred after stressing the front channel. Results obtained by stressing the back channel transistor are discussed. The back channel transconductance behavior is described.<<ETX>>","PeriodicalId":344373,"journal":{"name":"1990 IEEE SOS/SOI Technology Conference.

Fundamental differences concerning hot carrier effects were observed, and the impact on reliability was clarified. It appears that overall transistor performances are very sensitive to LDD optimization: low N-doping is recommended for low ionization rate, subsequent good blocking voltage, and intrinsic VG/sub bl/ increase during aging; high N-, in spite of small low time shifts, must be used carefully if initial blocking characteristics and bipolar effects are critical. In such cases, bulk transistor recommendations (high N- must be used in order to maintain high electric field under the transistor gate) may not be suitable for SOI transistors.<<ETX>>","PeriodicalId":344373,"journal":{"name":"1990 IEEE SOS/SOI Technology Conference.

This phenomenon, the MCCM (multistable charge controlled memory) effect, was first found in non-fully depleted SOI n-MOSFET samples operating at 77 K when negative back gate bias V/sub G2/ was applied. When the applied V/sub G2/ was swept from zero-voltage towards a negative value, e.g. -40 V, the V/sub T/ of the front gate would shift higher with rather good linearity within a V/sub G2/ span of about 20-30 V. The increase in V/sub T/ can be up to 2-3 V. The MCCM effect is only related to the coupling between the front and the back gates and does not depend on whether there are junctions or a potential well in the body. All the transistors investigated operate in the non-fully depleted regime for both high and low states at both room and low temperatures. The measurement results show that such multi-stable V/sub T/ behavior also occurs in the N/sup +/N/sup -/N/sup +/ accumulation mode SOI n-MOSFETs.<<ETX>>","PeriodicalId":344373,"journal":{"name":"1990 IEEE SOS/SOI Technology Conference.

Ion implantation of boron at 2.5 MeV was used in order to place the boron peak and residual tail of the boron distribution deep enough, so that a region of the original silicon material with acceptably low boron concentration persists near the active-layer-SiO/sub 2/ interface. The objective was to determine whether improvements in final uniformity were possible using the MeV implants compared to the more conventional epi-layer technique. Results show that a final thickness of 0.3 mu m of single crystal silicon on insulator can be produced with thickness nonuniformity of 28 to 30 nm averaged over 9 points on a 2\"*2\" area. The final oxidation-stripping steps contributed to most of this nonuniformity. Additional difficulties arose as a result of the extensive oxidation stripping used in the terminal processing steps.
