Found another typo on the MOSFET page of the Semiconductor book here:

The insulated-gate field-effect transistor (IGFET), also known as the metal oxide field effect transistor (MOSFET), is a derivative of the field effect transistor (FET). Today, most transistors are of the MOSFET type as components of digital integrated circuits. Though discrete BJT's are more numerous than discrete MOSFET's. The MOSFET transistor count within an integrated circuit may approach hundreds of a million.
The red text should read "may approach hundreds of millions." The adjective/numerical value hundreds is plural, and not exact, so the rest should be plural as well.

Also found one on the Superconducting devices page here in the fourth paragraph on the page:

The quantum mechanical nature of the cooper pair only allows it to exchange discrete amounts of energy, not continuously variable amounts. An absolute minimum quantum of energy is acceptable to the cooper pair. If the vibrational energy of the crystal lattice is less, (due to the low temperature), the cooper pair cannot accept it, cannot be scattered by the lattice. Thus, under the critical temperature, the cooper pairs flow unimpeded through the lattice.
The sentence in red should read:
"If the vibrational energy of the crystal lattice is less, (due to the low temperature), the cooper pair cannot accept it, and it cannot be scattered by the lattice."

One more found on the same page as my last post:

Josephson junctions: Brian Josephson won a Nobel prize for his 1962 prediction of the Josepheson junction. A Josephson junction is a pair of superconductors bridged by a thin insulator, as in Figure below (a), through which electrons can tunnel. The first Josephson junctions were lead superconductors bridged by an insulator. These days a tri-layer of aluminum and niobium is preferred. Electrons can tunnel through the insulator even with zero voltage applied across the superconductors.
Should be the "Josephson Junction," not the "Josepheson Junction."
