专利汇可以提供Schottky barrier diodes as impedance elements专利检索,专利查询,专利分析的服务。并且The reverse characteristic of Schottky barrier diodes provides easily fabricated, small area, high impedance elements for micropower circuits. Advantageously, the diodes are fabricated within semiconductive integrated circuit arrays by forming rhodium silicide on relatively high resistivity P-type silicon. Such diodes are particularly useful in the loads of flip-flops used as cells of a semiconductor memory.,下面是Schottky barrier diodes as impedance elements专利的具体信息内容。

  • 2. Apparatus as recited in claim 1 wherein the reverse impedance of the P-type Schottky barrier diode at 1 volt reverse-bias is about 20,000 ohms.
  • 3. Apparatus as recited in claim 1 wherein the reverse leakage current of the P-type Schottky barrier diode at a reverse voltage less than about 10 volts is between one ampere/cm.2 and 1,000 amperes/cm2.
  • 4. Apparatus as recited in claim 1 wherein the reverse leakage current of the P-type Schottky barrier diode at 1 volt reverse-bias is within an order of magnitude of 100 amperes/cm2.
  • 5. Apparatus as recited in claim 1 wherein the P-type silicon portion of the P-type Schottky barrier diode is doped to a surface concentration of less than about 5 X 1017/cm3.
  • 6. Apparatus as recited in claim 1 wherein the metal silicide portion of the P-type Schottky barrier diode is selected from the group consisting of rhodium silicide, platinum silicide, palladium silicide, and zirconium silicide.
