The present invention provides a metal stack structure that stabilizes the flatband voltage and threshold voltages of material stacks that include a Si-containing conductor and a Hf-based dielectric. This present invention stabilizes the flatband voltages and the threshold voltages by introducing a rare earth metal-containing layer into the material stack that introduces, via electronegativity differences, a shift in the threshold voltage to the desired voltage. Specifically, the present invention provides a metal stack comprising:a hafnium-based dielectric; a rare earth metal-containing layer located atop of, or within, said hafnium-based dielectric; an electrically conductive capping layer located above said hafnium-based dielectric; and a Si-containing conductor.

A fixing structure for a circuit board includes at least one board mounting hole in the circuit board, the board mounting hole having a guide hole and an insertion hole, and at least one board mounting member inserted through the board mounting hole, the board mounting member having a main body, a cover, and an insertion portion therebetween, wherein the insertion portion has a cross-sectional area smaller than either of the main body or the cover and is capable of fitting in the insertion hole of the board mounting hole.

An optical detection device for detecting an intensity of a light beam in a detection window and for detecting data transmitted by the light beam includes a first detection diode and an array of at least two second detection diodes in a detection window. In addition, provision is made for a first readout circuit connectable to the first detection diode, for reading out the first detection diode at a first readout speed to detect the data, and for a second readout circuit connectable to the second detection diodes, for reading out the second detection diodes at a second readout speed smaller than the first readout speed, so as to detect the intensity of the light beam. A fundamental consideration underlying the present invention is that although the provision of additional detection diodes in the detection window initially is associated with additional expense and a reduction of the surface area of the detection window which may effectively be utilized for data detection, these disadvantages are outweighed however, by the fact that this array of additional detection diodes in the detection window enables more effective and / or less expensive control of the alignment of the light beam transmitting the data with the detection window.
