摘要:
A manufacturing method for a glass product not having a rotatively symmetric body like an optical fiber fixing member but having a fine structure as of optical fiber engagement portions, to transfer the fine structure with a high precision without creating molding burrs, includes the steps of placing a glass material in a cavity defined by a lower mold, an upper mold, and a side mold, molding the glass material in the cavity with pressure into the glass product in so controlling that the glass material has a viscosity range of 10.sup.6.5 to 10.sup.9.5 poises at the beginning of molding operation with pressure, that the lower mold is at a temperature in a range such that the glass material indicates the above viscosity range, and that the upper and side molds are at a temperature in a range such that a converted viscosity of the glass material at the temperature of the upper and side molds is 5 to 100 times higher than the viscosity of the glass material at the temperature of the lower mold, and decreasing the temperature of the lower mold at the same time that or after the glass product begins to be molded with pressure. To produce an optical fiber fixing member, the lower mold has a mold face for molding optical fiber engagement portions of the optical fiber fixing member; the upper mold has a mold face for molding a bottom of the optical fiber fixing member; and the side mold has a mold face for molding a side face of the optical fiber fixing member.

The present disclosure provides a method to maximize the overall chip yield. This method combines a PV-aware deterministic circuit sizing process with a hybrid OPC operation, and integrates them into an analog layout migration platform, which attempts to efficiently compose a layout by inheriting knowledge from a legacy layout and imposing new specifications, circuit sizing and constraints. The present method provides a sizing process, which explores robust circuit sizes under different PV conditions, especially considering mismatch effects on sensitive analog devices. The analog layout migration is conducted along the sizing flow for efficient layout synthesis with a unique benefit to better evaluation of the PV-related post-layout effects. After finishing the sizing process, a hybrid OPC operation, which adopts global rule-based OPC and local model-based OPC along with the PV-band shifting, is performed as a post-processing step. Thereafter, a target mask layout is created with fast processing time, high wafer image fidelity, low mask complexity, and robust circuit performance under PV conditions. This present method provides an efficient solution to layout synthesis with respect to analog ICs by combining the deterministic sizing process with fast analog layout migration and hybrid OPC operations.

The present invention provides a method for increasing storage capacity of a disc drive by physically skewing a transducer in relation to a slider supporting the transducer. The physical skew angle of the transducer is configured to provide a predetermined zero skew position on the medium, which is capable of providing an increased storage capacity to the medium. To ascertain this zero skew position, a storage density or storage capacity of the medium may be ascertained for each of various zero skew positions on the medium. A desired storage density or capacity level is selected according to storage capacity requirements and the corresponding zero skew position is ascertained. The corresponding zero skew position may be implemented by physically skewing a transducer relative to a slider.
