Abstract: A dental carrier comprises a thermoplastic carrier. The thermoplastic carrier has a pattern structure. After heating the thermoplastic carrier, the thermoplastic carrier is provided with a user to be impressed by teeth or alveolar ridge for forming teeth or alveolar ridge model of the user. Compared to the prior art, the dental carrier of the present invention can provide the dental medicament contained in the pattern structure to be precisely applied and hold onto the treatment area and the medicament can be evenly coated on the teeth, root, or periodontal tissue for the treatment of teeth. When the dental carrier is not used to carry medicament, the pattern structure can improve the mechanical strength and fitness of the dental carrier to be used as a biteplate, orthodontic retainer, periodontal dressing for treatment or protection or mouth guard in sports.

Abstract: A power integrated circuit architecture (10) having a high side transistor (100) interposed between a control circuit (152) and a low side transistor (100) to reduce the effects of the low side transistor on the operation of the control circuit. The low side transistor has a heavily p-doped region (56) designed to reduce minority carrier lifetime and improve minority carrier collection to reduce the minority carriers from disturbing the control circuit. The low side transistor has a guardring (16) tied to an analog ground, whereby the control circuit is tied to a digital ground, such that the collection of the minority carriers into the analog ground does not disturb the operation of the control circuit. The low side transistor is comprised of multiple transistor arrays (90) partitioned by at least one deep n-type region (16), which deep n-type region forms a guardring about the respective transistor array.

Abstract: An array (90) of transistors (50) formed in a p-type layer (34), and including a second heavily doped p-type region (56) laterally extending proximate the drain of each transistor to collect minority carriers of the transistors. A deep n-type region (16) is formed in the p-type layer (34) and proximate a n-type buried layer (14) together forming a guardring about the drain regions of the plurality of transistors. The array of transistors may be interconnected in parallel to form a large power FET, whereby the heavily doped second p-type region (56) reduces the minority carrier lifetime proximate the drains of the transistors. The guardring (14, 16) collects the minority carriers (T1) and is isolated from the drains of the transistors. Preferably, the transistors are formed in a P-epi tank that is isolated by the guardring. The P-epi tank is preferably formed upon a buried NBL layer, and the deep n-type region is an N+ well extending to the buried NBL layer.

Abstract: A method for the fabrication of a light-sensing diode in a high-resistivity semiconductor substrate. A high-energy implant of ions into the substrate is patterned to form an annular well of the same conductivity type as the substrate; followed by a second high-energy implant of the opposite conductivity type, within the center of the annulus; followed by a third implant, of lower energy and high dosage, to form a region of the first conductivity type extending laterally near the substrate surface. The resulting diode junction is thereby patterned to include two planes near the substrate surface, allowing incident light to traverse the junction twice.

Abstract: A tank-isolated drain extended power device (50, 60, 70, 80) having an added laterally extending heavily doped p-type region (56, 62, 72) in combination with a p-type Dwell (32) which reduces minority carrier buildup. The p-doped regions are defined in a P-epi layer surrounded by a buried NBL region (14) connected with a deep low resistance drain region (16) forming a guardring. This additional laterally extending p-doped region (56,62,72) reduces minority carrier build up such that recovery time is significantly reduced, and power loss is also significantly reduced due to reduced collection time of the minority carriers. The device may be formed as an LDMOS device.
