HIGH PERFORMANCE ANALOG FOUNDRY BIPOLAR WPY PROCESS SUMMARY WPY is a 1.0 micron versatile low capacitance linear bipolar process providing excellent functionality at low cost. Features such as high value poly resistors, nitride capacitors, Schottky and Zener diodes and two-layer metal (including thick Metal2) allow low current circuits to be built with high packing densities. npn Cross-Section Emitter Base Collector Table 1: NPN Parameters (0.6 x 4.0 µm emitter) Parameter Condition Value Units fT Vce=2 V 4.0 GHz HFE Ic=10 µA Vce=2 V VAF 85 120 V 34 V BVCBO Ic=10 µA BVCEO Ic=10 µA 24 V CJE Vbe=0 10 fF CJC Vbc=0 8 fF CJS Vcs=0 97 fF L OC OS L OC OS IS IS DC E pitaxy (n-) Table 2: Lateral PNP Parameters BP BP BN S u b s tra te (p -) Parameter Condition Value Units fT Vce=2 V 20 MHz HFE Ic=10 µA Vce=2 V Vsub=-2 V 55 VAF Minimum geometry npn fT curve 5 .0 50 V BVCEO Ic=1 µA 23 V CJS Vcs=0 3 fF 4 .0 3 .0 Vc e = 2 V fT (G H z ) 2 .0 1 .0 0 .0 1 .E - 0 6 1 .E - 0 5 1 .E -0 4 1 .E -0 3 1 .E - 0 2 IC ( A ) Features High-speed NPN transistors Lateral PNP transistors BVCEO 24 V typical (20 V min) 0.9 fF/sq µm Nitride capacitor 3 resistors including HV polysilicon resistor Schottky Diodes 0.5 V Vf Zener Diodes 5.3 V BVz ESD Protection Kit High packing density Very low leakage currents Applications Linear applications DC-DC converters Switching regulators Power management Table 3: Resistor Values Type Value Units Polysilicon 3.2 ± 0.5 kΩ Base 550 ± 50 Ω PR 67.5 ± 7.5 Ω Table 4: Key Design Rules Feature Min µm Spacing Emitter 1.0 x 2.5 or 1.5 x 1.5 Poly (EP) resistor width 1.5 2.0 Base and PR resistor width 3.0 1.5 Contact 1.0 x 2.5 or 1.5 x 1.5 1.4 1st layer metal 2.0 2.0 2nd layer metal 4.0 3.0 Information relating to products and services furnished herein by Zarlink Semiconductor Inc. or its subsidiaries is believed to be reliable.
