According to one embodiment, a semiconductor wafer comprises a plurality of solder bumps for providing device contacts formed over a functional region of the semiconductor wafer, and one or more support rings surrounding the functional region. The one or more support rings and the plurality of solder bumps are formed so as to have substantially matching heights. The presence of the one or more support rings causes the semiconductor wafer to have a substantially uniform thickness in the functional region after a thinning process is performed on the semiconductor wafer. A method for fabricating the semiconductor wafer comprises forming the plurality of solder bumps over the functional region, and forming the one or more support rings surrounding the functional region before performing the thinning process on the semiconductor wafer.

This relates to a heating device including a solar energy collector, the solar energy collector transferring collected solar energy to outside air. First collector panels are used to heat outside air which heated air is led to a heater, for example a space heater. Second collector panels are used to transfer solar energy to air led to a heat exchanger of a heat pump. The heat pump transfers the extracted heat to heat storage. The stored heat is added to the air coming from the first collector panels if the temperature of the air coming from the first collector panels is below a predetermined temperature.
摘要:
A top drain MOSgated device has its drain on the top of semiconductor die and its source on the bottom of the die substrate. Parallel spaced trenches extend from the die top surface through a drift region, a channel region and terminate on the substrate region. The bottoms of each trench receive a silicide conductor to short the substrate source to channel regions. The silicide conductors are then insulated at their top surfaces and gate electrodes are placed in the same trenches as those receiving the channel/source short.
摘要:
A MOSgated trench device has a reduced on resistance by forming a less than about a 13 nm thick strained SiGe layer on the silicon surface of the trenches and forming a thin (30 nm or less) layer of epitaxially deposited silicon on the SiGe layer which epi layer is converted to a gate oxide layer. The conduction channel formed by the SiGe layer is permanently strained to increase its mobility particularly hole mobility.
