Available in PDF, EPUB and Kindle. Book excerpt: A low-temperature process for forming ohmic contacts to moderately doped GaAs has been optimized using a PdGe metallization scheme. Minimum specific contact resistivity of 1.5 x 10−6 -cm2 has been obtained with a low anneal temperature of 250 C. Results for optimizing both time and temperature are reported and compared to GeAu n-GaAs contacts. Material compositions was analyzed by x-ray photoelectron spectroscopy and circuit metal interconnect contact resisitivity to the low-temperature processed PdGe contacts is reported. For the lowest temperature anneals considered, excess Ge on the ohmic contact layer is suspected of degrading interconnect metal contacts, while higher temperature anneals permitted interconnect metal formation with negligible contact resistivity. Atomic force microscopy measurements showed that the PdGe surface morphology is much more uniform than standard GeAu contacts.

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: This dissertation is focused on the development of Ohmic and Schottky contacts to both nand p-type Gallium Nitride for use in microelectronic and optical devices. The goal is to develop low resistance contacts with greater thermal budgets and superior thermal aging characteristics to those commonly in use today as well as to understand the mechanisms by which these contacts may fail. In addition, p-type Ohmic contacts have been used to fabricate light emitting diodes (LEDs) which display far superior aging properties than those made with conventional Ni/Au contacts. Ohmic contacts to p-GaN were fabricated using a variety of refractory materials. The materials examined were of three basic types: boride, nitride, and the refractory metal Ir. The boride family includes W2B, W2B5, CrB2, ZrB2, and TiB2. The nitrides examined were TaN, TiN, and ZrN. Contacts based on these materials were fabricated using either a GaN//Ni/Au/X/Ti/Au, GaN//X/Ti/Au, or GaN//Ni/X/Au scheme, where X is the refractory material. Contact resistances as low as ~1 x 10-4 ohm/cm2 were consistently achieved after annealing at temperatures from 500-1000°C for 60 s in N2 using these materials for p-GaN with a carrier concentration of ~1 x 1017 cm-3.

This book was released on 2018-08-16 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gold based alloys, commonly used as ohmic contacts for solar cells, are known to react readily with GaAs. It is shown that the contact interaction with the underlying GaAs can continue even at room temperature upon aging, altering both the electrical characteristics of the contacts and the nearby pn junction. Au-Ge-Ni as-deposited (no heat treatment) contacts made to thin emitter (0.15 micrometer) GaAs diodes have shown severe shunting of the pn junction upon aging for several months at room temperature. The heat-treated contacts, despite showing degradation in contact resistance did not affect the underlying pn junction. Au-Zn-Au contacts to p-GaAs emitter (0.2 micrometer) diodes, however, showed slight improvement in contact resistance upon 200 C isothermal annealing for several months, without degrading the pn junction. The effect of aging on electrical characteristics of the as-deposited and heat-treated contacts and the nearby pn junction, as well as on the surface morphology of the contacts are presented.
