  • Key storage device and key generation method
    Patent number: 11961567
    Abstract: A key storage device comprising a first key unit and a second key unit is disclosed. The first key unit is configured to output a first logic value through, comprising: a first setting circuit configured to output a first setting voltage; and a first inverter comprising a first output transistor having a first threshold voltage, configured to receive the first setting voltage and generate the first logic value. The second key unit is configured to output a second logic value through a second node, comprising: a second setting circuit configured to output a second setting voltage; and a second inverter comprising a second output transistor having a second threshold voltage, configured to receive the second setting voltage and generate the second logic value. The absolute value of first threshold voltage is lower than which of the second threshold voltage. The first setting voltage is higher than the second setting voltage.

  • Method for making a light emitting diode by electroless plating
    Patent number: 8039279
    Abstract: One embodiment of the invention relates to a method of manufacturing a light emitting diode. The method includes forming an insulating layer on an area, not covered by a seed layer, of at least one of a p-type semiconductor layer and an n-type semiconductor layer, wherein the impurity concentration varies on the surface of the area; and immersing at least part of the seed layer into an electrolyte having metal ions which tend to reduce and deposit on the seed layer under no bias voltage.
