Metal Etchant Compositions and Methods of Fabricating a Semiconductor Device:

One of Christopher Kemper Ober's recent patents focuses on metal etchant compositions and the methods employed to fabricate semiconductor devices. The composition itself comprises an organic peroxide (ranging from 0.1 wt % to 20 wt %), an organic acid (ranging from 0.1 wt % to 70 wt %), and an alcohol-based solvent (ranging from 10 wt % to 99.8 wt %). Uniquely, this metal etchant composition can be used in an anhydrous system, presenting notable advantages in semiconductor manufacturing processes.

Radiation-Sensitive Composition and Pattern-Forming Method:

In another significant patent, Ober introduces a radiation-sensitive composition that includes particles comprising a metal oxide as the principal component, accompanied by an organic solvent. The composition incorporates first metal atoms, such as zinc, boron, aluminum, gallium, thallium, germanium, antimony, bismuth, tellurium, or a combination thereof. Of particular importance is the fact that the first metal atom content constitutes no less than 50 atomic % of the total metal atoms in the radiation-sensitive composition. This patent also encompasses a pattern-forming method that involves applying the radiation-sensitive composition to form a film, exposing the film, and developing the exposed film.
