In a semiconductor device for generating complementary PWM signals for, for example, controlling an inverter, a dead time is flexibly added by using a simple architecture. A dead time addition unit adds time elapsing until a value of a timer reaches a set value of a register as a first dead time at a rise of a first PWM signal. On the other hand, time elapsing until the value of the timer reaches a set value of another register is added as a second dead time at a rise of a second PWM signal.

A method is disclosed for forming an image sensor. In a semiconductor wafer containing a p-type region an n-type connection region is formed within the p-type region. An n-type photodiode region is formed in the p-type region connected to the connection region. A field oxide isolation region is formed, having a part that is over portions of the n-type connection region and the n-type photodiode region. This part of the field oxide region covers the area where these regions are connected and extends into these regions. The edges of this part of the field oxide region fall within these regions, while leaving a distance between these edges and pn junctions formed by the connection region and the p-type region and the n-type photodiode region and p-type region. A gate oxide is formed over regions not covered by field oxide. An extended gate structure is formed extending from above this part of the field oxide isolation region to a distance beyond the connection region so as to accommodate a channel of an n-channel MOSFET. The drain region of the n-channel MOSFET is formed, with the connection region acting as the source. A blanket transparent insulating layer is deposited.

A X-Y addressable MOS imager sensor method and apparatus wherein a semiconductor based MOS sensor having an array of pixels forming the X-Y addressable MOS imager, the X-Y addressable MOS imager having a plurality of the pixels such that each pixel within the plurality of pixels has a photodetector with a reset mechanism that adjusts the photodetector potential to a predetermined potential level employs the measuring a plurality of reset levels with two different elapsed times between reset and measurement of the reset level, a comparison circuit operatively coupled to the means for measuring to determine a difference in reset levels, a predetermined set of transfer functions used to identify effective signal levels of the photodetectors, and determines from the difference which transfer function is applicable to that photodetector range of accumulated light. In response to the difference detected, transfer functions are applied to the charge read out from the photodetector. The transfer functions comprise a first transfer function that is pre-photodetector saturation function and a second transfer function that is a post-photodetector saturation transfer function. These transfer functions are applied to two reset levels of the photodetector within the same row readout period. The response to the difference can be the application of a series of digital adds and digital multiplies. The difference between the 2 reset levels is used to calculate the effective pixel signal level from the difference.

The invention relates to a CCD of the buried-channel type comprising a charge-transport channel in the form of a zone (12) of the first conductivity type, for example the n-type, in a well (13) of the opposite conductivity type, in the example the p-type. In order to obtain a drift field in the channel below one or more gates (9, 10a) to improve the charge transfer, the well is provided with a doping profile, so that the average concentration decreases in the direction of charge transport. Such a profile can be formed by covering the area of the well during the well implantation with a mask, thereby causing fewer ions to be implanted below the gates (9, 10a) than below other parts of the channel. By virtue of the invention, it is possible to produce a gate (10a) combining a comparatively large length, for example in the output stage in front of the output gate (9) to obtain sufficient storage capacity, with a high transport rate.
