摘要:
A method for forming a power circuit package (45) having a porous base structure (20) electrically isolated from a first porous die mount (21) and a second porous die mount (22) by a dielectric material (29). The porous base structure (20) is bonded to a second surface of the the dielectric material (29) whereas the first porous die mount (21), and the second porous die mount (22) are bonded to a first surface of the dielectric material (29). Simultaneous with the bonding step, the porous base structure (20), the first porous die mount (21), and the second porous die mount (22) are impregnated with a conductive material. Semiconductor die (32, 33, 34, and 35) are bonded to the impregnated die mounts. The semiconductor die (32, 33, 34, and 35) are then encapsulated by a molding compound.

A method of forming an insulated gate semiconductor device (10). A field effect transistor and a bipolar transistor are formed in a portion of a monocrystalline semiconductor substrate (11) that is bounded by a first major surface (12). A control electrode (19) is isolated from the first major surface by a dielectric layer (18). A first current conducting electrode (23) contacts a portion of the first major surface (12). A second current conducting electrode (24) contacts another portion of the monocrystalline semiconductor substrate (11) and is capable of injecting minority carriers into the monocrystalline semiconductor substrate (11). In one embodiment, the second current conducting electrode contacts a second major surface (13) of the monocrystalline semiconductor substrate (11).

A bracket for mounting the head rail of a venetian blind to a support surface of a window opening. The head rail is in the form of channel member of U-shaped cross section comprising a base member pivotally mounted to a support surface, a pair of flexible, resilient legs depending from the base member having tangs at their terminal ends engageable with locking beads running the length of the head rail channel and rotatable to a position wherein the tangs release the channel member.
摘要:
A mounting bracket which is simple, economic to manufacture and easy to install for the detachable mounting the head rail of a venetian blind assembly in a window opening or the like. In one form the bracket is of box-like configuration having panels with means for securing it to the side, top or front support surface of the window frame, a hinged front panel permitting pivoting from an open position to receive the ends of the head rail and locking means for latching the front panel in a closed position with the head rail in place. In another form, the bracket has flexible legs with tangs to engage with longitudinal ribs in the head rail and is pivotally mounted to release from the head rail when desired. Other features include a bumper insert for the head rail to resist transverse displacement when raising and lowering the blind and a novel control rod and ladder string arrangement facilitating complete closing of all the slats.

A device, memory, method and system directed to fast data storage on a block storage device that reduces operational wear on the device. New data is written to an empty write block with a number of write blocks being reused. A location of the new data is tracked. Metadata associated with the new data is written. A lookup table may be updated based in part on the metadata. The new data may be read based the lookup table configured to map a logical address to a physical address.

A semiconductor device has a well region formed within a substrate. A gate structure is formed over a surface of the substrate. A source region is formed within the substrate adjacent to the gate structure. A drain region is formed within the substrate adjacent to the gate structure. A first clamping region and second clamping region below the source region and drain region. A trench is formed through the source region. The trench allows the width of the source region to be reduced to 0.94 to 1.19 micrometers. A plug is formed through the trench. A source tie is formed through the trench over the plug. An interconnect structure is formed over the source region, drain region, and gate structure. The semiconductor device can be used in a power supply to provide a low voltage to electronic equipment such as a portable electronic device and data processing center.
