    摘要: Methods of conducting wafer level burn-in (WLBI) of semiconductor devices are presented wherein systems are provided having at least two electrodes (210, 215). Electrical bias (920) and/or thermal power (925) is applied on each side of a wafer (100) having back and front electrical contacts for semiconductor devices borne by the wafer. A pliable conductive layer (910) is described for supplying pins on the device side of a wafer with electrical contact and/or also for providing protection to the wafer from mechanical pressure being applied to its surfaces. Use of a cooling system (950) is also described for enabling the application of a uniform temperature to a wafer undergoing burn-in. Wafer level burn-in is performed by applying electrical and physical contact (915) using an upper contact plate to individual contacts for the semiconductor devices; applying electrical and physical contact using a lower contact plate (910) to a substrate surface of said semiconductor wafer; providing electrical power (920) to said semiconductor devices through said upper and lower second contact plates from a power source coupled to said upper and lower contacts plates; monitoring and controlling electrical power (935) to said semiconductor devices for a period in accordance with a specified burn-in criteria; removing electrical power at completion of said period (955); and removing electrical and physical contact to said semiconductor wafer (965).

    摘要: Systems for wafer level burn-in (WLBI) of semiconductor devices (210, 215) are presented. Systems having at least two electrodes for the application of electrical bias and/or thermal power on each side of a wafer (100) having back (105) and front (110) electrical contacts for semiconductor devices borne by the wafer (100) is described. Methods of wafer level burnin using the system are also described. Furthermore, a pliable conductive layer (220) is described for supplying pins or contacts (110) on device side of a wafer with electrical contact. The pliable conductive layer (220) can allow for an effective series R in each of the devices borne by the wafer (100), thus helping keep voltage bias level consistent. The pliable conductive layer can also prevent damage to a wafer when pressure is applied to it by chamber contacts (210, 215) and pressure onto surfaces of the wafer (100) during burn-in operations. A cooling system (660) is also described for enabling the application of a uniform temperature to the wafer (100) undergoing burn-in.
