Abstract:
Techniques are disclosed for forming a transistor with one or more additional gate spacers. The additional spacers may be formed between the gate and original gate spacers to reduce the parasitic coupling between the gate and the source/drain, for example. In some cases, the additional spacers may include air gaps and/or dielectric material (e.g., low-k dielectric material). In some cases, the gate may include a lower portion and an upper portion. In some such cases, the lower portion of the gate may be narrower in width between the original gate spacers than the upper portion of the gate, which may be as a result of the additional spacers being located between the lower portion of the gate and the original gate spacers. In some such cases, the gate may approximate a “T” shape or various derivatives of that shape such as  -shape or  -shape, for example.

Claim (Index 1):
An integrated circuit including at least one transistor, the integrated circuit comprising:\n a body including semiconductor material; a source region and a drain region, the body between the source and drain regions, the source and drain regions including semiconductor material and dopant; a gate structure at least above the body, the gate structure including one or more metals, the gate structure having a lower portion and an upper portion, the lower portion closer to the body than the upper portion; a gate dielectric between the body and the gate structure; a first spacer and a second spacer, the first and second spacers including one or more dielectrics, the gate structure between the first and second spacers, the gate dielectric between the first and second spacers; and a third spacer between the first spacer and the lower portion of the gate structure, the third spacer also between the first spacer and the gate dielectric, the third spacer including compositionally different material from the first spacer.
