The present invention consists of an implantable device with at least one package that houses electronics that sends and receives data or signals, and optionally power, from an external system through at least one coil attached to the at least one package and processes the data, including recordings of neural activity, and delivers electrical pulses to neural tissue through at least one array of multiple electrodes that is/are attached to the at least one package. The invention, or components thereof, is/are intended to be installed in the head, or on or in the cranium or on the dura, or on or in the brain. Variations of the embodiments depend on the physical locations of the coil(s), package(s) and array(s) with respect to the head, cranium, dura, and brain. Novel features of the present invention include the small size of the implantable package which houses the controller, the high number of electrodes that are provided for stimulation and/or sensing and stimulation, and the methods for manufacturing such a device. These features have unique applications in neural stimulation to treat or prevent disorders or disease.

The present invention consists of an implantable device with at least one package that houses electronics that sends and receives data or signals, and optionally power, from an external system through at least one coil attached to the at least one package and processes the data, including recordings of neural activity, and delivers electrical pulses to neural tissue through at least one array of multiple electrodes that is/are attached to the at least one package. The device is adapted to electrocorticographic (ECoG) and local field potential (LFP) signals. The output signals provide control for a motor prosthesis and the inputs signals provide sensory feedback for the motor prosthesis. The invention, or components thereof, is/are intended to be installed in the head, or on or in the cranium or on the dura, or on or in the brain.

The invention is directed to firm bonding between semiconductor dies etc bonded to a lead frame and wire-bonding portions of the lead frame by ultrasonic Al wire bonding, and the prevention of shortcircuit between the semiconductor dies etc due to a remaining portion of the outer frame of the lead frame after the outer frame is cut. By extending the wire-bonding portion etc on the lead frame in a wire-bonding direction and connecting the wire-bonding portion etc to the outer frame of the lead frame through a connection lead etc, the ultrasonic vibration force in the ultrasonic Al wire bonding is prevented from dispersing and the Al wire and the wire-bonding portion etc are firmly bonded. The outer frame is cut after a resin sealing process is completed. Even when a portion of the outer frame remains on the side surface of the resin package, connection between the connection lead etc and other hanging lead etc are prevented by providing a notch etc in the outer frame between the connection lead etc and the hanging lead etc.
