A method of filling a trench is described and includes depositing a dielectric liner with a high ratio of silicon oxide to dielectric liner etch rate in fluorine-containing etch chemistries. Silicon oxide is deposited within the trench and etched to reopen or widen a gap near the top of the trench. The dielectric liner protects the underlying substrate during the etch process so the gap can be made wider. Silicon oxide is deposited within the trench again to substantially fill the trench.

This invention relates to a system and method to generate a private, auditable, evidentiary quality record of the location-history of an asset or person. This invention addresses ten critical improvements over existing systems that are proposed or used for metering for payment services for tolling roads, parking or pay-as-you-drive insurance, namely, cost-effective location accuracy in harsh signal environments, evidentiary assurance of location estimation, handling of dynamic and stationary positioning in a single device, high-ratio compression for a set of stationary positions in urban canyon, high-ratio compression for a dynamic tracklog in urban canyon, high-ratio compression for a set of asset motion behaviors, a method of remote device health check, including anti-tampering, removal of residual price assignment errors, anonymous use without on-board maps, and a method of deconsolidating payments to multiple payees with multiple payment regimes. This system can be applied to road-pricing, congestion-pricing, metered-by-the-minute parking and pay-as-you-drive insurance, incorporating privacy management, and legal admissibility of the evidentiary record. This same device can also be applied to vehicular fleets, military ordinance, or other location audits for assets whether motorized or not, as might be needed in evidence of contract fulfillment or other forms of non-realtime geofencing audits.

A magnetic write head provides a significant write field and minimal adjacent track erasure, and lends itself to improved manufacturability. The write head includes a pedestal throat height that defines a bottom pole, P1, and that is substantially recessed from the air bearing surface. The write head further includes a top pole, P2, that defines a nose that is closer to the air bearing surface than the pedestal zero throat. This design achieves a relatively high ratio of the off-track to on-track field. As an example, a 1:4 ratio could be achieved to significantly mitigate the erasure problem of the adjacent tracks resulting from magnetic flux saturation.

Symmetrical/asymmetrical bidirectional S-shaped I-V characteristics with trigger voltages ranging from 10 V to over 40 V and relatively high holding current are obtained for advanced sub-micron silicided CMOS (Complementary Metal Oxide Semiconductor)/BiCMOS (Bipolar CMOS) technologies by custom implementation of P₁-N₂-P₂-N₁//N₁-P₃-N₃-P₁ lateral structures with embedded ballast resistance 58, 58A, 56, 56A and periphery guard-ring isolation 88-86. The bidirectional protection devices render a high level of electrostatic discharge (ESD) immunity for advanced CMOS/BiCMOS processes with no latchup problems. Novel design-adapted multifinger 354/interdigitated 336 layout schemes of the ESD protection cells allow for scaling-up the ESD performance of the protection structure and custom integration, while the I-V characteristics 480 are adjustable to the operating conditions of the integrated circuit (IC). The ESD protection cells are tested using the TLP (Transmission Line Pulse) technique, and ESD standards including HBM (Human Body Model), MM (Machine Model), and IEC (International Electrotechnical Commission) IEC 1000-4-2 standard for ESD immunity. ESD protection performance is demonstrated also at high temperature (140° C.). The unique high ratio of dual-polarity ESD protection level per unit area, allows for integration of fast-response and compact protection cells optimized for the current tendency of the semiconductor industry toward low cost and high density-oriented IC design. Symmetric/asymmetric dual polarity ESD protection performance is demonstrated for over 15 kV HBM, 2 kV MM, and 16.5 kV IEC for sub-micron technology.
