    摘要: Provided is a “castled” active area mask. A castled active area mask is one which has been lengthened to extend beyond its intended intersection with a tunnel dielectric to form the tunnel window of an EEPROM cell, and has also been widened in at least a portion of the extension. For example, in one preferred embodiment, a castled extension may have a “T” shape. The castled active area generated by such a mask provides a buffer to absorb field oxide encroachment before it reaches the EEPROM cell's TD window. A mask in accordance with the present invention may be used to fabricate EEPROM cells which are not subject to TD window size variations due to field oxide encroachment, and EEPROM cell arrays of increased density.

    摘要: The present invention is a method and apparatus whereby two NMOS or PMOS devices connected in series in a stacked gate configuration formed on SOI exhibit improved ESD response characteristics. The shared source-drain region between the two devices is formed to have a dopant depth in the shared region that does not extend through the silicon layer to the BOX layer. This provides a common body for the two devices, and thus a single parasitic bipolar transistor is formed between the drain of one NMOS or PMOS device and the source of the second NMOS or PMOS device. Simultaneous snapback occurs for the two devices through the common body. A further embodiment includes a method of forming two or more stacked gate NMOS or PMOS devices on SOI. The method includes protecting the shared source-drain region between two NMOS or PMOS devices during a final doping step and silicide processing.

    摘要: Complementary metal-oxide-semiconductor (CMOS) integrated circuits with bipolar transistors and methods for fabrication are provided. A bipolar transistor may have a lightly-doped base region. To reduce the resistance associated with making electrical contact to the lightly-doped base region, a low-resistance current path into the base region may be provided. The low-resistance current path may be provided by a base conductor formed from heavily-doped epitaxial crystalline semiconductor. Metal-oxide-semiconductor (MOS) transistors with narrow gates may be formed on the same substrate as bipolar transistors. The MOS gates may be formed using a self-aligned process in which a patterned gate conductor layer serves as both an implantation mask and as a gate conductor. A base masking layer that is separate from the patterned gate conductor layer may be used as an implantation mask for defining the lightly-doped base region.
