    摘要: Trench gate MOSFET devices may be formed using a single mask to define gate trenches and body contact trenches. A hard mask is formed on a surface of a semiconductor substrate. A trench mask is applied on the hard mask to predefine a body contact trench and a gate trench. These predefined trenches are simultaneously etched into the substrate to a first predetermined depth. A gate trench mask is next applied on top of the hard mask. The gate trench mask covers the body contact trenches and has openings at the gate trenches. The gate trench, but not the body contact trench, is etched to a second predetermined depth. Conductive material of a first kind may fill the gate trench to form a gate. Conductive material of a second kind may fill the body contact trench to form a body contact.

    摘要: A photonic device package with a passively aligned lens cap is disclosed. The lens cap is positioned with an unobstructed view of the lens portion of the lens cap. A header holding a photonic device, is moved relative to the cap or vice versa until the video display system indicates that the photonic device is aligned to the lens. The cap is held in alignment by forming at least one weld point between the cap and the header. A subsequent hermetic sealing process can be used to permanently seal the cap to the header.

    摘要: A method and apparatus for multi-protocol uplink access defines two protocols and maps each to one of a user's access service class (ASC) and quality of service (QoS). A first uplink access protocol type is defined in which a random access channel (RACH) burst is sent and an acquisition indicator channel (AICH) burst is sent, and a channel assignment grant is sent on another downlink channel. A second uplink access protocol type is defined in which a RACH preamble is sent and an AICH burst is sent.
