چکیده

This work describes the improved uniformity of short gate length (sub100nm) T-gate lithography observed for InP HEMT devices through the development of a nonannealed ohmic contact process. The incorporation of such a process allows the reversal of ohmic and gate levels as part of a standard device process flow. This eliminates fluctuations in the gate geometry that result from the spinning of gate resists across a non-planar surface i.e. between the source and drain contacts.

0.15μm In0.4GaAs/In0.4AlAs Metamorphic HEMT’s (M-HEMT’s) Using A Novel Triple Shaped Gate Structure Assisted By PMGI Resist

In this paper, a novel gate technology with triple shaped gate structure has proposed and developed in order to suppress unwanted gate fringing capacitance. Because high gate stem height was difficult to fabricate by means of conventional direct electron beam (E-Beam) lithography method, additional PMGI sacrificial layer was utilized in this new scheme. Increasing gate stem height as an amount ...

112-GHz, 157-GHz, and 180-GHz InP HEMT Traveling-Wave Amplifiers - Microwave Theory and Techniques, IEEE Transactions on

We report traveling-wave amplifiers having 1–112 GHz bandwidth with 7 dB gain, and 1–157 GHz bandwidth with 5 dB gain. A third amplifier exhibited 5 dB gain and a 180GHz high-frequency cutoff. The amplifiers were fabricated in a 0.1m gate length InGaAs/InAlAs HEMT MIMIC technology. The use of gate-line capacitive-division, cascode gain cells and low-loss elevated coplanar waveguide lines have y...

Continued research into the development of III–V high-electron mobility transistors (HEMTs), specifically the minimization of the device gate length, has yielded the fastest performance reported for any three terminal devices to date. In addition, more recent research has begun to focus on reducing the parasitic device elements such as access resistance and gate fringing capacitance, which beco...

0.1 μm InP HEMT MMIC Fabrication on 100 mm Wafers for Low Cost, High Performance Millimeter-Wave Applications

Northrop Grumman Space Technology (NGST) has recently initiated process development for fabricating 0.1 μm InGaAs/InAlAs/InP High Electron Mobility Transistor (HEMT) MMICs on 100 mm InP substrates. Successful development of this process will further reduce costs for InP HEMT MMICs and rival those of GaAs-based HEMT MMICs, including GaAs-based metamorphic HEMT technology, with superior performan...

A Comparative Study of As, Sb and P-based Metamorphic HEMT

Metamorphic HEMT (MHEMT) structures on As, Sb, and P-based buffers with different grading profiles were grown by molecular beam epitaxy. Structural, electrical, and optical characterization were used to correlate buffer layer design and growth parameters with channel carrier mobility, surface morphology, and photoluminescence efficiency. All MHEMTs studied in this work exhibited excellent trans...
