Publication number: 20260153559Abstract: A tester apparatus is described of the kind having contact with terminals on a wafer for purposes of testing the wafer. A dielectric gas is used to reduce arcing between the contact. A stationary structure and a portable structure have complimentary gas interfaces that engage when the portable structure engages with the stationary structure. A gas box has a channeling block connected to a dielectric gas pressure regulator and a nitrogen gas pressure regulator and connected to a gas supply passage to selectably provide nitrogen or dielectric gas to the gas supply passage. A tray has a portion that is electrically conductive to make contact with a rear wafer terminal, vacuum passages, and each vacuum passage has an enlarged section to reduce.Type: ApplicationFiled: January 27, 2026Publication date: June 4, 2026Applicant: AEHR TEST SYSTEMSInventors: Donald P. Richmond, II, Jovan Jovanovic, Scott E. Lindsey

Publication number: 20250224423Abstract: A method of testing an integrated circuit of a device is described. Air is allowed through a fluid line to modify size of a volume defined between the first and second components of an actuator to move a contactor support structure relative to the apparatus and urge terminals on the contactor support structure against contacts on the device. Air is automatically released from the fluid line through a pressure relief valve when pressure of the air in the fluid line reaches a predetermined value. The holder is moved relative to the apparatus frame to disengage the terminals from the contacts while maintaining the first and second components of the actuator in a substantially stationary relationship with one another. A connecting arrangement is provided including first and second connecting pieces with complementary interengaging formations that restricts movement of the contactor substrate relative to the distribution board substrate in a tangential direction.Type: ApplicationFiled: March 26, 2025Publication date: July 10, 2025Applicant: AEHR TEST SYSTEMSInventors: Scott E. Lindsey, Junjye Yeh, Jovan Jovanovic, Seang P. Malathong

Patent number: 12163999Abstract: An apparatus is described for burn-in and/or functional testing of microelectronic circuits of unsingulated wafers. A large number of power, ground, and signal connections can be made to a large number of contacts on a wafer. The apparatus has a cartridge that allows for fanning-in of electric paths. A distribution board has a plurality of interfaces that are strategically positioned to provide a dense configuration. The interfaces are connected through flexible attachments to an array of first connector modules. Each one of the first connector modules can be independently connected to a respective one of a plurality of second connector modules, thereby reducing stresses on a frame of the apparatus. Further features include for example a piston that allows for tight control of forces exerted by terminals onto contacts of a wafer.Type: GrantFiled: November 29, 2023Date of Patent: December 10, 2024Assignee: AEHR TEST SYSTEMSInventors: Donald P.
