Abstract: A flash electrical erasable programmable read only memory structure that utilizes hot carrier injection for programming and negative gate voltage to carry out channel erase operations. Characteristic of the memory structure includes a triple well structure having a P-well and an N-well located within a P-type substrate, wherein the N-well isolated the P-well from the P-type substrate. Therefore, an independently isolated triple well structure is established during memory erase operation.

Abstract: A process for simultaneously forming a self-aligned contact, a local interconnect and a self-aligned silicide in a semiconductor device. An oxide layer is deposited over a gate structure, a source region and a drain region formed on a substrate of the semiconductor device. The gate structure may be a multi-layer structure including a polysilicon gate, a silicon nitride layer and a tungsten silicide layer. The oxide layer deposited over the gate, source and drain is etched to define portions of the oxide layer which will form contact areas of a self-aligned contact and a local interconnect of the semiconductor device. An amorphous silicon layer is then deposited over the etched oxide layer to a thickness selected such that substantially the entire thickness of remaining portions of the amorphous silicon layer will be consumed during a subsequent silicidation reaction.

The buried layer fabrication sequence for forming a buried layer having a first conductivity type includes the steps of: forming a first dielectric layer on a semiconductor substrate, the semiconductor substrate having a second conductivity type; forming a first mask layer having openings on top of the first dielectric layer, wherein the openings in the first mask layer are positioned over the regions where the first buried layer is formed; exposing the semiconductor substrate in the regions where openings in the first mask layer are formed; forming a second dielectric layer; removing the second dielectric layer; and forming a semiconductor layer.

Abstract: A method of fabricating a BiCMOS device in which PMOS and NMOS transistors are formed prior to a base/emitter structure of a bipolar transistor. In forming the base/emitter structure, a blanket implant of a first impurity is introduced into a base region of a semiconductor substrate. An insulating layer is deposited and then patterned to expose a portion of the base region at an emitter window. A polysilicon layer is deposited on the insulating layer and into the emitter window. The polysilicon layer is patterned to provide the desired configuration at the emitter window, whereafter the remaining polysilicon acts as a mask for etching of the insulating layer. Thus, etching of the insulating layer is performed in a self-aligning manner. Self-alignment is also utilized in providing a base-link region and in providing a silicide layer.

Abstract: A method of plasma etching tungsten containing films such as is found in semiconductor interconnects. The etch method is conducted under reactive ion etch conditions in a plasma etch reactor using a gas mixture of CF.sub.4 and O.sub.2. The O.sub.2 preferably makes up 20% to 60% of the gas mixture by volume. The etch method is highly selective to titanium disilicide, titanium nitride and silicon dioxide.
