摘要:
A semiconductor memory device and a method for manufacturing the same, capable of increasing the effective cell capacitor area by virtue of steps each defined between a semiconductor substrate surface and each field oxide film formed over the semiconductor substrate. Over the semiconductor substrate, a thin film MOSFET is formed, which includes a charge storage electrode and an active region both connected with a charge storage electrode of each memory cell through a charge storage contact hole. With this structure, a second effective capacitor area is obtained, thereby enabling the capacitance to increase. Also, the semiconductor substrate is connected with a substrate of the thin film MOSFET by a substrate contact hole. Accordingly, it is possible to control the electrical characteristic of the thin film MOSFET. In spite of a decrease in cell area, a higher charge storage capacity can be also obtained.

A method and apparatus for implanting dopant material into a substrate of semiconductive material in a preselected pattern without utilizing a mask comprises the use of a source template which is formed of the desired dopant material in the configuration of the pattern to be implanted. Ions of the dopant material are sputtered from the template by bombardment with an ionized gas, and these dopant ions are then filtered from unwanted ion species and accelerated into the substrate while remaining in the original template pattern.

摘要:
An ESD protection device is formed in an integrated circuit by an N-channel grounded-gate transistor. This protection device has a polysilicon gate, just as other P- and N-channel transistors in the integrated circuit device, but the siliciding of the protection device is controlled so that adverse effects of ESD events are minimized. There are no silicide areas created on top of the polysilicon gate of the protection device, nor on the source/drain regions near the gate and self-aligned with the gate, as there is for other transistors made by the CMOS process. The siliciding of the protection transistor near the gate is prevented by using a deposited oxide layer as a mask, and this oxide layer is also used to create sidewall spacers for the transistor gates. The sidewall spacers are used in creating self-aligned silicided areas over the source/drain regions, self-aligned with the gates, for all P- and N-channel transistors except the protection transistors. A standard process for making CMOS integrated circuits having self-aligned silicided source/drain areas may be used, with the addition of only one non-critical masking step to block the siliciding of protection transistors.
