摘要： An ensemble of test structures comprising arrays of polysilicon plate MOS capacitors for the measurement of electrical quality of the MOSFET gate insulation is described. The test structures also measure plasma damage to these gate insulators incurred during metal etching and plasma ashing of photoresist. The structures are formed, either on test wafers or in designated areas of wafers containing integrated circuit chips. One of the test structures is designed primarily to minimize plasma damage so that oxide quality, and defect densities may be measured unhampered by interface traps created by plasma exposure. Other structures provide different antenna-to-oxide area ratios, useful for assessing plasma induced oxide damage and breakdown. The current-voltage characteristics of the MOS capacitors are measured by probing the structures on the wafer, thereby providing timely process monitoring capability.

摘要： A single-chip common-drain JFET device comprises a Drain, two gates and two source arranged such that two common-drain JFETs are formed therewith. Due to the two JFETs merged within a single chip, no wire bonding connection is needed therebetween, thereby without parasitic inductance and resistance caused by bonding wire, and therefore improving the performance and reducing the package cost. The single-chip common-drain JFET device may be applied in buck converter, boost converter, inverting converter, switch, and two-step DC-to-DC converter to improve their performance and efficiency. Alternative single-chip common-drain JFET devices are also provided for current sense or proportional current generation.

摘要： In a LED driver using a depletion mode transistor to serve as a current source, the depletion mode transistor is self-biased for providing a driving current to drive at least one LED, thereby requesting no additional control circuit to control the depletion mode transistor. The driving current is independent on the supply voltage coupled to the at least one LED, thereby requesting no additional voltage regulator, reducing the circuit size, and lowering the cost.
