Abstract: Performance of a semiconductor device is improved without increasing an area size of a semiconductor chip. For example, a source electrode of a power transistor and an upper electrode of a capacitor element have an overlapping portion. In other word, the upper electrode of the capacitor element is formed over the source electrode of the power transistor through a capacitor insulating film. That is, the power transistor and the capacitor element are arranged in a laminated manner in a thickness direction of the semiconductor chip. As a result, it becomes possible to add a capacitor element to be electrically coupled to the power transistor while suppressing an increase in planar size of the semiconductor chip.

Abstract: A heat dissipation structure of an SMD LED includes a substrate, an SMD LED and at least one engaging member. A plurality of conductive copper foils is covered on an upper end face of the substrate. Two electrodes are provided on a lower surface of the SMD LED and are respectively connected to two copper foils on the upper end face. An engaging hole extends through one of the copper foils adjacent the SMD LED and through the substrate.

Accordingly, heat generated by the SMD LED can be directly transferred to an exposed lower end face of the substrate through the engaging member for more heat dissipation and less luminance decrease of the SMD LED.

Abstract: A double-RESURF LDMOS transistor has a gate dielectric structure including a shallow field “bump” oxide region and an optional raised dielectric structure that provides a raised support for the LDMOS transistor's polysilicon gate electrode. Fabrication of the shallow field oxide region is performed through a hard “bump” mask and controlled such that the bump oxide extends a minimal depth into the LDMOS transistor's drift (channel) region. The hard “bump” mask is also utilized to produce an N-type drift (N-drift) implant region and a P-type surface effect (P-surf) implant region, whereby these implants are “self-aligned” to the gate dielectric structure. The N-drift implant is maintained at Vdd by connection to the LDMOS transistor's drain diffusion. An additional Boron implant is utilized to form a P-type buried layer that connects the P-surf implant to the P-body region of the LDMOS transistor, whereby the P-surf implant is maintained at 0V.

Abstract: The width of scribe lines may be reduced in semiconductor devices by applying a process technique in which trenches may be formed first from the rear side on the basis of a required width of the corresponding trenches, while subsequently it may be cut into the substrate from the front side on the basis of a reduced thickness of the corresponding saw blades, thereby also enabling a reduction of the scribe line width. Furthermore, contamination of the front side, i.e., of the metallization system, may be reduced, for instance, by performing an optional intermediate cleaning process.
