Calculating how the measured damage to these large AR testers impacts product is a serious issue that has not yet been resolved. Without the ability to predict the damage impact to product, and hence to quantitatively establish antenna design rules, the only way to ensure product reliability is to reduce damage as best we can and to use tight design rules. Such practice is extremely costly and provides no assurance. The purpose of this paper is to illustrate a quantitative methodology to deal with the above-mentioned problem using a real example.","PeriodicalId":268624,"journal":{"name":"2000 Symposium on VLSI Technology.

We present an ultra-high-density embedded loadless four-transistor SRAM cell for 0.13-/spl mu/m logic LSIs. The cell size is 0.99 /spl mu/m/sup 2/, which is the smallest of all reported SRAM cells. In addition, its fabrication process is fully compatible with CMOS logic technologies. The following three technologies reduce the cell area to less than 1 /spl mu/m/sup 2/, and provide highly stable operation at 1.2 V. The double-exposure technique using KrF excimer laser lithography with complementary phase-shift masks reduces the spacing between the drive-transistor gate and the word line. Using the borderless-contact etching process expands shared contact up to 0.21 /spl mu/m without contact leakage current to obtain sufficient misalignment tolerance. The thickness of the gate dielectrics in the cell is controlled to suppress the direct tunneling current to less than the off-state current in order to retain the cell data from -40 to 125/spl deg/C.","PeriodicalId":268624,"journal":{"name":"2000 Symposium on VLSI Technology.

Using this technology, the advantages of SOI MOSFETs are quantitatively proven. Excellent body-fixing capability of this SOI MOSFET, and high-quality on-chip inductance is demonstrated for RF/analog LSIs.

Thus V/sub t/ can be set according to standby power requirement or device design (well and halo engineering), forward body bias is then applied to improve speed or to reduce active power. No compromise in I/sub off/ results if the forward bias is applied when the circuits are active, during which time I/sub off/ and the leakage current are small compared to the switching current. Therefore a low-power CMOS strategy should use a MOSFET as a four-terminal device with a fast top gate and a slow bottom gate shared by a block. Deep-trench isolation with STI provides fine-grain isolation for body bias blocks without area penalty. Making the body available also improves the device analog properties and enables new applications. We present an active-well VCO/mixer as an example.","PeriodicalId":268624,"journal":{"name":"2000 Symposium on VLSI Technology. Digest of Technical Papers (Cat.
