摘要:
This invention discloses a semiconductor power device disposed in a semiconductor substrate and the semiconductor substrate has a plurality of trenches. Each of the trenches is filled with a plurality of epitaxial layers of alternating conductivity types constituting nano tubes functioning as conducting channels stacked as layers extending along a sidewall direction with a “Gap Filler” layer filling a merging-gap between the nano tubes disposed substantially at a center of each of the trenches. The “Gap Filler” layer can be very lightly doped Silicon or grown and deposited dielectric layer. In an exemplary embodiment, the plurality of trenches are separated by pillar columns each having a width approximately half to one-third of a width of the trenches.

Catheter devices having an expandable balloon for delivering a therapeutic agent to a body site. In one aspect, one or more sheaths are disposed around the balloon with the therapeutic agent being disposed within the sheath, being disposed over the sheath, being contained in the space between the sheath and the balloon, or being otherwise associated with the sheath. In another aspect, the balloon includes a micro-electromechanical system (MEMS) for drug delivery.

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.

A tube-in-tube assembled parison for preparation of an elongated medical device. The parison if formed by assembling in tube-in-tube fashion a first tube of orientable polymer material and a second tube formed of orientable polymer material disposed around the first tube, with an adhesive tie layer disposed between the first and second tubes. The tubes are brought into contact to form a unitary parison. The adhesive may allow movement between the polymer layers during balloon blowing. The first tube, or the second tube, or both, may have been longitudinally pre-stretched after formation thereof but before assembly of the parison.

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.
摘要:
A CMOS semiconductor integrated circuit device. The CMOS device includes an NMOS device comprising a gate region, a source region, and a drain region and an NMOS channel region formed between the source region and drain region. A silicon carbide material is formed within the source region and formed within the drain region. The silicon carbide material causes the channel region to be in a tensile mode. The CMOS device also has a PMOS device comprising a gate region, a source region, and a drain region. The PMOS device has a PMOS channel region formed between the source region and the drain region. A silicon germanium material is formed within the source region and formed with in the drain region. The silicon germanium material causes the channel region to be in a compressive mode.
