Title: Optimization of time on CF{sub 4}/O{sub 2} etchant for inductive couple plasma reactive ion etching of TiO{sub 2} thin film

Abstract

In this work, we investigate the optimum etching of titanium dioxide (TiO{sub 2}) using inductive couple plasma reactive ion etching (ICP-RIE) on our fabricated devices. By using a combination of CF{sub 4}/O{sub 2} gases as plasma etchant with ratio of 3:1, three samples of TiO{sub 2} thin film were etched with different time duration of 10 s, 15 s and 20 s. The ion bombardment of CF{sub 4} gases with plasma enhancement by O{sub 2} gas able to break the oxide bond of TiO{sub 2} and allow anisotropic etch profile with maximum etch rate of 18.6 nm/s. The sample was characterized by using optical profilometer to determine the depth of etched area and scanning electron microscopy (SEM) for etch profile characterization.

  • Solar selective surface photothermal absorbers consisting of thin-film Si with a submicron surface texture have been produced by reactive ion etching an evaporated Si film on a Mo layer. Such surfaces formed on 316 stainless steel and other substrates have solar absorptivities of 0.9 and calculated thermal emissivities of approx.0.2 at 200 /sup 0/C. These selective surfaces are stable in air to 500 /sup 0/C.
  • One of the key processing concerns in the integration of PbZr[sub x]Ti[sub 1[minus]x]O[sub 3](PZT) thin film capacitors into the existing VLSI for ferroelectric or dynamic random access memory applications is the patterning of these films and the electrodes. In this work, the authors have identified a suitable etch gas (CCl[sub 2]F[sub 2]) for dry etching of PZT thin films on RuO[sub 2] electrodes. The etch rate and anisotropy have been studied as a function of etching conditions. The trends in the effect on the etch rate of the gas pressure, RF power and O[sub 2] additions to the etch gasmore » have been determined and an etching mechanism has been proposed. It was found that ion bombardment effects are primarily responsible for the etching of both PZT and RuO[sub 2] thin films. Etch rates of the order of 20--30 nm/min were obtained for PZT thin films under low gas pressure and high RF power conditions. The etch residues and the relative etch rates of the components of the PZT solid solution were determined using XPS. The results show that the etching of PbO is the limiting factor in the etch process.« less
  • The authors are developing a tool for semiconductor thin film growth based on the plasma immersion ion implantation technique. This compact, inexpensive, high throughput implanter will allow separate control of dose rate, ion energy and substrate temperature while mitigating charging effects. The present system employs a cylindrical inductive plasma source (35 cm diameter, 400 kHz, 500 W) which has been characterized using Langmuir and magnetic probes. Radial and axial profiles of plasma density and electron temperature along with measurements of induced plasma current will be presented for a range of neutral pressure and rf power. Comparisons will be made tomore » a model of inductive source operation. Initial results of oxide growth on silicon and III-V materials will be presented.« less
  • Very thin silicon dioxide (<100 A) has been widely used as a tunnel barrier for floating gate electrically erasable read only memory (EEPROM) devices. Small tunneling areas are required in the new EEPROM cell generations and the use of reactive ion etching (RIE) plasma is mandatory in order to define windows with a diameter <1.2 ..mu..m. The tunnel oxide has to be grown in these windows opened in the thicker (150--300 A) gate oxide. The surface damage induced by plasma RIE requires postetch treatments. In this paper, we deal with the effects induced on the oxide characteristics by different postetchmore » treatments. The analysis has been focused on both the recovery of the surface damage and the electrical characteristics of a 95-A-thick tunnel oxide grown after different postetch processes. The oxide degradation under current stress has been evaluated using metal--oxide--semiconductor capacitors. The best preoxidation treatment that we found among our experiments has also been tested on an EEPROM cell. The tunnel oxide degradation, i.e., the cell threshold voltage shift, was found to be very negligible after 10/sup 5/ write--erase cycles.« less
  • Reactive and anisotropic etching of magnetic tunnel junction (MTJ) stacked films has been achieved using pulse-time-modulated (TM) plasma. While corrosion and delamination of MTJs are observed in continuous wave discharge plasma, a chlorine pulse-time-modulated plasma achieved a high MTJ etching rate without corrosion or delamination. The authors think that the negative ions enhance the chemical reactions on the surface of magnetic films. The magnetic characteristics are also significantly improved by using TM plasma because of reduced residues and improved tapered profiles. Accordingly, TM plasma etching is a promising candidate for high-rate and damage-free MTJ etching for magnetoresistive random access memorymore » devices.« less
