A 1 dimensional or 2 dimensional array of micromirror devices comprises a device substrate with a 1st surface and a 2nd surface, control circuitry disposed on said 1st surface and a plurality of micromirrors disposed on said 2nd surface. Each micromirror comprises a reflective surface that is substantially optically flat, with neither recesses nor protrusions. Such a 1 dimensional or 2 dimensional array of micromirror devices may be used as a spatial light modulator (SLM). Methods of fabricating arrays of micromirror devices are also disclosed. Such methods generally involve providing a device substrate with a 1st surface and a 2nd surface, fabricating control circuitry on the 1st surface, and fabricating micromirrors on the 2nd surface, such that the reflective surfaces of the micromirrors are substantially optically flat, with neither recesses nor protrusions.

A through silicon via reaching a pad from a second surface of a semiconductor substrate is formed. A penetration space in the through silicon via is formed of a first hole and a second hole with a diameter smaller than that of the first hole. The first hole is formed from the second surface of the semiconductor substrate to the middle of the interlayer insulating film. Further, the second hole reaching the pad from the bottom of the first hole is formed. Then, the interlayer insulating film formed on the first surface of the semiconductor substrate has a step shape reflecting a step difference between the bottom surface of the first hole and the first surface of the semiconductor substrate. More specifically, the thickness of the interlayer insulating film between the bottom surface of the first hole and the pad is smaller than that in other portions.

Impure portions such as air bubbles and gelled portions in a liquid are removed so that the liquid can be discharged with improved cleanliness. Under condition that a return flow path and a liquid discharge flow path are closed, a pump chamber is expanded, thereby sucking the liquid in a liquid container portion into a pump chamber through a filter. Under condition that a vent port of the filter and the return flow path are opened and a liquid introducing flow path, the liquid discharge flow path, and a pump inlet flow path are closed, the pump chamber is contracted, thereby returning the liquid in the pump chamber toward the filter so that air in the filter is exhausted to the outside. Under condition that the return flow path and the pump inlet flow path are closed, the pump chamber is contracted, thereby discharging the liquid from the nozzle.

A radiation detector includes an array of detector pixels each including an array of detector cells. Each detector cell includes a photodiode biased in a breakdown region and digital circuitry coupled with the photodiode and configured to output a first digital value in a quiescent state and a second digital value responsive to photon detection by the photodiode. Digital triggering circuitry is configured to output a trigger signal indicative of a start of an integration time period responsive to a selected number of one or more of the detector cells tranisitioning from the first digital value to the second digital value. Readout digital circuitry accumulates a count of a number of transitions of detector cells of the array of detector cells from the first digital state to the second digital state over the integration time period.

A thin film deposition apparatus used to produce large substrates on a mass scale and improve manufacturing yield.

A flash memory device, and a method of operating the same, is disclosed. The array of the flash memory device is arranged in pages of memory cells, each page having memory cells associated into groups of memory cells within the page for purposes of fail bit detection in program verification. For example, these groups may correspond to sectors within the page. In a programming operation, the verify process determines whether each group of memory cells within the page has fewer than a selected ignore bit limit for the sector. If not, additional programming is required for the insufficiently programmed cells in the page. By applying a fail bit detection threshold for each of multiple groups within the page, the efficiency of error correction coding in the flash memory is improved. A similar verify and fail bit detection approach may be used in erase and soft programming operations.

The heat sink is thicker than the wiring board. The heat sink has a protruded portion protruding to outside from the side surface of the heat sink, the protruded portion is located on the upper surface of the wiring board outside the through-hole, and the lower surface of the protruded portion contacts to the upper surface of the wiring board. When the semiconductor device is manufactured, the heat sink is inserted from the upper surface side of the wiring board.

A first insulating layer including a first contact pad made of conductive polysilicon and a second insulating layer including a second contact pad are formed over a semiconductor silicon layer.

To completely suppress or minimize the voids formed between the insulating substrate and the IC chip in order to prevent the problems of separation and cracking of the chip caused by the aforementioned voids. The present invention is preferably adopted for the Chip Six Package type package or other package types equipped with solder bumps or other external connecting terminals directly beneath the IC chip. For insulating substrate (3), on its chip-carrying surface, there is pattern element (6) in the region beneath the IC chip and free of conductor pattern elements (4) in addition to conductor pattern element (4) for forming electrical connection between the electrode pads and the external connecting terminals of the chip. Said pattern element (6) divides said region into plural small regions A. IC chip (2) is bonded through die paste on insulating substrate (3) such that an end of conductor pattern element (4), pattern element (6) and divided small regions A are covered. Pattern element (6) acts to reduce the shifting of die paste (9) before curing due to the surface tension. As a result, the formation of voids beneath the chip can be completely prevented or minimized.
