摘要： An SRAM device has STI regions separated by mesas and doped regions including source/drain regions, active areas, wordline conductors and contacts in a semiconductor substrate is made with a source region has 90° transitions in critical locations. Form a dielectric layer above the active areas. Form the wordline conductors above the active areas transverse to the active areas. The source and drain regions of a pass gate transistor are on the opposite sides of a wordline conductor. Form the sidewalls along the crystal plane. Form the contacts extending down through to the dielectric layer to the mesas. Substrate stress is reduced because the large active area region formed in the substrate assures that the contacts are formed on the surfaces of the mesas are in contact with the mesas formed on the substrate and that the surfaces of the silicon of the mesas are shielded from the contacts.

摘要： A process for fabricating a lateral photodiode element, for an image sensor cell, with an increased depletion region, has been developed. The process features protecting a portion of the semiconductor substrate from ion implantation procedures used to create the P well, and the N well components of the lateral photodiode element. The protected region, or the space between the P well and N well regions, allows a larger depletion region to be realized, when compared to lateral photodiode elements in which the N well and P well regions butt. The space between the P well and N well regions, between about 0.2 to 0.4 um, result in the desired P well—intrinsic or P type semiconductor substrate—N well, (P-I-N), lateral photodiode element.
